The term "CA" is short for cyanoacrylate, a one-part instant cure adhesive. A chemical synthesis process produces CA by
changing acetate to acrylate. This process is the first step in making CAs. Stick Fast™ CA is then further
distilled until this crude acrylate becomes a CA monomer that is at least 99.5% pure. This high level of
purity gives Stick Fast™ superior cure strength, reduces cure times, and helps increase stability and shelf
Stick Fast™ cyanoacrylates are MADE IN THE USA, providing you with the freshest materials available and
are produced at the highest industrial quality standards.
A high pH level initiates the curing mechanism of CA. In most cases, the moisture found on any surface combined with
the elements of the surface creates an adequate curing environment. Organic acids are used as stabilizers in
the manufacturing of CAs, which is why the higher the acid level is on the bonding surface the slower the cure.
These acidic stabilizers are a major facilitator in keeping the CA in its liquid form. Stick Fast™ CAs are
ethyl based, surface-insensitive formulated for bonding a wide range of similar and dissimilar materials.
Stick Fast™ ACTIVATOR will accelerate the cure faster than moisture alone and may be the only way to
create a cure on some highly acidic surfaces. Using too much ACTIVATOR will create an exothermic
reaction that causes foaming, reducing bonding strength. Using AEROSOL ACTIVATOR allows for a
lighter, more even application that minimizes this foaming tendency.
MSDS forms are available for the CA Adhesives:
Accelerator Aerosols | Accelerator Pumps | Epoxy | Glues
The MSDS forms are PDF files and require either Adobe Reader, a third party software, or a browser plug-in.
Store unopened bottles in a dry area away from direct sunlight, ideally at less than 50°F. Unopened bottles
of CA may be stored in a refrigerator but freezing is not recommended. If stored in a refrigerator, bring up
to room temperature before using.
DO NOT refill bottles. Refilling will shorten the shelf life of the added CA and may create contamination.
Store opened bottles in a cool, dry area away from direct sunlight.
Do not store opened bottles in a refrigerator or freezer; atmospheric moisture in the bottle will condense, causing
premature curing and reducing shelf life. The cold temperatures will also affect viscosity.
When storing CA for an extended time, place opened bottle in a moisture tight jar (plastic or glass) with
TMI's DRY PAK. DRY PAK's color changes from blue to pink indicating that the desiccant is no longer
absorbing moisture. To reuse the DRY PAK when this happens, place the PAK into a microwave oven for
about two to three minutes to dry out the desiccant. The Pak will again turn blue. Use caution, the DRY
PAK can get very hot in the microwave oven.
DO NOT STORE CA NEXT TO PUMP SPRAY ACTIVATORS
The ACTIVATOR'S fumes escaping through the pump sprayer can initiate curing within the CA bottle.
ALWAYS USE EYE PROTECTION KEEP AWAY FROM CHILDREN.
All STICK FAST™ CA adhesives are non-toxic. However, CAs are an irritant and we recommend you insure proper ventilation. For those that are highly sensitive, a respirator may be necessary.
If CA comes in contact with eyes SEE A PHYSICIAN. Flush eye with water, and do not force the bonded area apart. DO NOT USE DE-BONDER. When corneal surface and eyelid are bonded together, treat with a suitable anti-irritant ointment and allow eye to remain closed. Bond separation will occur naturally.
If accidental skin bonding occurs use DE-BONDER, or use warm, soapy water to separate skin. Gradually work the skin free. Do not use excessive force to pull the bonded area apart.
STICK FAST™ ACTIVATOR and DE-BONDER contain solvents that are extremely flammable. Do not puncture or incinerate aerosol containers. Do not use near source of ignition or spark. Do not store above 120°F. Use with adequate ventilation and avoid inhalation of vapors. Incase of skin or eye contact, flush with water. If ingested or eye contact occurs see a physician.
Use a minimum amount of CA - MORE IS NOT BETTER. Testing applications on scrap materials is recommended.
Before bonding, be sure surfaces are clean, especially hard surfaces such as metal, plastics, and glass. To clean surfaces use acetone or alcohol.
Before bonding or crack-filling wood that will be stained or clear finished, we suggest a quick spray of
lacquer to the area. This seals the surface and helps prevent the CA from being absorbed into surrounding
areas. After CA application, the area can be sanded or turned; leaving a surface that can be polished and finished but not stained.
Use a CA viscosity that will not be absorbed completely into the surface to be bonded. Apply CA to one
surface only. For an instant bond, spray Stick Fast™ ACTIVATOR on other surface. Press parts together.
What it bonds - TECH DATA:
Stick Fast cyanoacrylates are formulated as a surface-insensitive instant adhesive. It is used for applications that require exceptionally fast cure speeds on difficult to bond
surfaces, acidic surfaces, wood, PVC, substrates that contain plasticizers, certain types of EPDM, etc. Stick Fast cyanoacrylates are excellent for almost all other basic materials.
All of our CAs can be used for gap filling. Use CA-MEDIUM or CA-THICK for most applications, adding fine sawdust after applying the CA to blend in
the fill. For a fast cure, wait 5 to 8 seconds, and then lightly spray with ACTIVATOR. For large cracks, dents, or holes, fill void level with a mixture of 1 part baking
soda – 10 parts fine sawdust then carefully apply CA-THIN. The soda will accelerate the cure deep in the
crack or gap. USE CAUTION: WAIT before lathe turning, the top layer will cure first. The material deep
in the crack will remain liquid for a longer period of time even when using an activator to accelerate the
cure. Sanding shortly after applying the CA will help blend in the fill. To reduce or eliminate absorption
marking in the surrounding wood, lightly spray area with a lacquer sealer prior to filling.
Finishing with CA:
Use CA-THIN, CA-MEDIUM, orCA-THICK as a protective finish. Apply a small amount of CA-MEDIUM or CA-THICK (approximately the size of a quarter) to four layers of blue shop type paper towel or sturdy cloth. Quickly apply in a circular motion to surface, reapplying CA to keep paper towel wet but not soak through all layers. Polyester pillow filler wrapped and taped around a stick to act as a swab may also be used to create a smooth finish application. Continuously apply liberal amounts of CA-THIN to surface as the swab smoothes the CA. Insure CA is cured before lathe turning to prevent uncured material from spraying. CA may be reapplied, sanded, polished, or lacquered after cured. For a high gloss finish, over coat with a spray on lacquer and buff. A cured CA surface is non-stainable. Use a light spray of AEROSOL ACTIVATOR to accelerate the cure; pump bottle Activator has a tendency to cause foaming and marking. Note: CA will heat up as it cures especially in large volume.
Sealing with CA:
CA-THIN or CA-MEDIUM will penetrate into wood to strengthen, seal and bond delicate, spalted or punky areas. Sealed wood can be turned, sanded, or finished. Insure CA is cured before lathe turning
to prevent uncured material from spraying. Use CA-THIN to seal, bond, and preserve natural edge bark.
Accelerating CA cure time:
Stick Fast™ ACTIVATOR creates a cure in 2 to 3 seconds. Wait 5 to 8 seconds after CA application before spraying directly on the CA. To accelerate bonding applications, typically apply CA to one surface and ACTIVATOR to the other, then press together. Spray on ACTIVATOR very lightly; too much will cause foaming and will weaken the bond. AEROSOL ACTIVATOR will minimize or eliminate foaming when spraying directly on CA and is ideal when CA is used for finishing or sealing. When large amounts of CA are used, especially when filling with CA, the activator will start the cure process on the top creating a skin where the material under the skin may be still liquid. WAIT additional time and exercise caution before lathe turning under these conditions.
Precision application of CA:
Our unique CHANGE-A-TIP system with various tips allows a precise, controlled application. The quick change feature allows easy change of different tip sizes and replacement of clogged tips. For micro applications of CA-THIN a FLEX TIP is also available to slip fit over the standard bottle spout. Our protected pin TIP-OPENER accessory provides a higher precision opening than cutting the standard bottle spout tip.
Reduce Clogged Tips
One of the most irritating parts of using CA's is the clogging of the bottle tip after a few uses. The normal remedy to this problem is to scrape the cured plug off, push the plug out, or to cut the tip back. If scraped with a fingernail, uncured CA may cause fingers to stick together. Cutting the tip back makes a larger opening, which creates less control of application. To reduce clogging after dispensing hold the bottle upright and lightly tap the bottom on a hard surface. Any remaining CA should drain back from the tip. You can also squeeze the bottle slightly, causing a burping action, forcing the remaining CA out. In both cases, use caution where you are aiming the tip. Another method is to use our CHANGE-A-TIP precision dispensing accessory, a low cost and quick way to solve this problem. The adapter cap provides a quickchange of a clogged tip, just 1/4 turn of the tip, pull, discard, and replace or soak in acetone to dissolve the cured CA. If cleaning with a solvent, insure tip is completely dry before reusing to prevent contamination.
There are five different CA products available. All of the CAs can be used to bond or seal a wide range of similar or dissimilar materials. The set time varies with the bonding surface, humidity, viscosity, and volume or thickness of each application.
When bonding, choose a viscosity that will not be completely absorbed into the surfaces to be bonded. For uneven bonding surfaces, select a thicker viscosity to fill the gaps. Apply a small amount. More is not better. Stick Fast™ CAs can bond a variety of materials such as wood, metal, glass, rubber, ceramics, and plastics.
TMI Products' Stick Fast™ Cyanoacrylate Adhesives are made in the U.S.A. and is a minimum of 99.5% pure to assure the highest quality. These products are single component, solvent-free systems and are rapid, room temperature cure. Stick Fast™ CA-THIN, CA-MEDIUM, CA-THICK, GA-GEL are surface-insensitive formulated for bonding a wide range of similar and dissimilar materials. CA-FLEXIBLE, a rubberized cyanoacrylate with similar properties, is also available.
Stick Fast Cyanoacrylates should be applied in small amounts to one surface only. The parts should then be joined together under slight pressure. The pressure need only be applied for several seconds. Curing occurs rapidly, allowing for bonded parts to be handled within 4 to 60 seconds for most applications. Full cure is normally within 24 hours.
Applying ACTIVATOR will reduce cure time. However, ACTIVATOR may reduce the overall strength of the bond depending on the amount used. Over use of activator will result in a high exothermic reaction, which creates foaming or bubbling, which further reduces overall strength. Testing, therefore, is recommended to confirm affect. Spraying activator on one surface and applying adhesive on the other, and then pressing the two together normally achieves the best bonding results. Lightly using AEROSOL ACTIVATOR to spray directly on cyanoacrylate normally achieves the best results with reduced or no foaming.
Cure Speed vs. Substrate
Cure speed will be dependent upon the substrate used. Higher the viscosity of cyanoacrylates results in longer cure times. The table below shows the fixture time on different substrates at 22°C and 50% relative humidity using CA-THIN.
Cure Speed vs. Humidity
The following chart shows the tensile strength developed with time at different levels of humidity. The overall rate of cure is dependent upon the percentage of relative humidity.
Cyanoacrylates should not be used in pure oxygen/oxygen rich environments. Also, it is not recommended as a sealant for chlorine or other strong oxidizing materials.
The surface of the substrate must be clean and free of rust inhibitors, grease, oil, mold release agents, and other contaminants in order to ensure a good bond. The overall bond strength on painted parts may be determined by the strength of adherence of the paint to the substrate.
Handling Precautions (see MSDS for more information)
All of the Stick Fast™ Cyanoacrylate adhesives are non-toxic and do not constitute a health hazard. Normal precautions should be observed. Fumes may be an irritant and should be use in areas where there is adequate ventilation. KEEP AWAY FROM CHILDREN
Accidental skin bonding may occur. Use warm, soapy water to separate skin or use TMI's DE-BONDER. Gradually work skin free. Do not use excessive force to pull bonded area apart: this will only result in tearing skin and/or cause irritation that is not necessary.
Should eye contact occur, flush with water and see a physician. Do not use solvents or DE-BONDER or force the bonded area apart. When the corneal surface and eyelid are bonded together treat with a suitable anti-irritant ointment and allow the eye to remain closed. Bond separation will occur naturally with time.
Unopened container: Cyanoacrylates are ideally stored in a cold, dry environment in unopened containers. Optimal storage temperature is between 33°F and 50°F and may be stored in a refrigerator. Do not store in freezer.
Opened container: A dry environment will extend the shelf life. For optimal storage, place cyanoacrylate in a moisture barrier container (PET plastic or glass) with TMI's drying agent, DRY PAK. Do not put cyanoacrylate in freezer because moisture will condense within the bottle and reduce the shelf life. Colder temperatures will also affect viscosities. To prevent contamination of unused product, do not return any material to its original container. Do not store with or next to ACTIVATOR; fumes will migrate to cyanoacrylate bottles and cause premature curing.
