Tech Marketing’s Stick Fast™ Cyanoacrylate Adhesives are made in the USA 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. Application: 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. For detailed and diverse applications, see User Guidelines. Typical Properties of Uncured Materials: Chemical Type: Ethyl Cyanoacrylate Appearance Clear Liquid Flash Point: >176oF (80oC) Vapor Pressure <1 mbar Viscosities CA-Thin 5 CPS @ 25oC CA-Medium 500 CPS @ 25oC CA-Thick 2000 CPS @ 25oC CA-Gel Paste Cure Speed vs. Activator
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. Values are without the use of Activator

Higher the viscosity of cyanoacrylates results in longer cure times. The table below shows the fixture time on different substrates at 22oC and 50% relative humidity using CA-THIN.

Also, it is not recommended as a sealant for chlorine or other strong oxidizing materials. Surface Preparation 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. 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 Stick Fast™ 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. Storage Unopened container: Cyanoacrylates are ideally stored in a cold, dry environment in unopened containers. Optimal storage temperature is between 33oF and 50oF. 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 Stick Fast™ DRY PAK. Do not put cyanoacrylate in refrigerator or 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. |
