TM Scotch-Weld Instant Adhesives Technical Data May 2019 Product Description 3M Scotch-Weld Instant Adhesives are single component, high strength cyanoacrylate adhesives. Features One component, high strength adhesives that cure at room temperature. Products provide varying cure times, bond strengths, and viscosities. Can be used to bond a variety of substrates including many rubbers, plastics, and metals. Economical to use as it requires only drops of adhesive to provide strong bonds to many metals, plastics, and rubbers. Description 3M Scotch-Weld Instant Adhesive CA4 is a high-strength, very fast setting, multi-purpose cyanoacrylate adhesive that cures at room temperature with very low bonding pressures. It has particularly good adhesion to most cured rubbers. 3M Scotch-Weld Instant Adhesive CA5 is a high-strength, slow setting cyanoacrylate adhesive that cures at room temperature. Its relatively high viscosity is especially useful where some gap filling is desired for bonding rough or uneven surfaces. The longer set rate allows more time for proper alignment of parts to be bonded. Meets CID A-A- 3097, Type II, Class 3. 3M Scotch-Weld Instant Adhesive CA7 is a high-strength, extremely fast setting cyanoacrylate adhesive that cures quickly at room temperature. It has excellent adhesion to many metals, plastics and rubbers, and produces bonds with more shock and impact resistance than many typical cyanoacrylate adhesives. 3M Scotch-Weld Instant Adhesive CA8 is a high-strength, rapid- setting cyanoacrylate adhesive that cures at room temperature. It has excellent adhesion to many metals, plastics and rubbers, and produces bonds with more shock resistance than many typical cyanoacrylate adhesives. Meets CID A-A-3097, Type II, Class 2. 3M Scotch-Weld Instant Adhesives Description (continued) 3M Scotch-Weld Instant Adhesive CA9 is a high-strength cyanoacrylate adhesive that cures slower than many cyanoacrylates at room temperature. The longer set rate allows more time for proper alignment of parts before bonding takes place. It has excellent adhesion to many metals, plastics and rubbers, and produces bonds with more shock and impact resistance than many typical cyanoacrylate adhesives. Meets CID A-A-3097, Type II, Class 3. 3M Scotch-Weld Instant Adhesive CA40 is a high-strength, very fast- setting cyanoacrylate adhesive that cures at room temperature with very low bonding pressures. It has particularly good adhesion to many difficult to bond substrates such as EPDM rubber, aluminum and flexible vinyl. 3M Scotch-Weld Instant Adhesive CA40H is a high-strength cyanoacrylate adhesive. It is a higher viscosity, slightly slower setting version of Scotch-Weld CA40. It has particularly good adhesion to many difficult to bond substrates, such as aluminum, EPDM rubber, and flexible vinyl. Scotch-Weld CA40H exhibits good resistance to soap solutions and isopropyl alcohol. Its high viscosity helps prevent run off during application, and its slower set time allows additional time for proper alignment of parts. 3M Scotch-Weld Instant Adhesive Gel CA50 is a high-strength, surface insensitive, gel cyanoacrylate adhesive. Its gel consistency allows it to be used in many non-sag vertical applications, and to fill gaps up to .020 inches. The very slow cure rate allows plenty of time to reposition parts. Meets CID A-A-3097, Type II, Class 5. 3M Scotch-Weld Instant Adhesive CA100 is a high-strength cyanoacrylate adhesive. Its relatively high viscosity (approximately 3000 cps) allows gap-filling capability up to .020 inches. It has high T-Peel strength, thermal shock resistance, impact resistance, and excellent metal bonding capabilities. Meets CID A-A-3097, Type II, Class 3. - 2 -
