3M™ Scotch-Weld™ Instant Adhesive CA50 Gel 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 inch. The very slow cure rate allows plenty of time to reposition parts.
One component, high strength adhesives that cure at room temperature
Slower cure speed than traditional instant adhesives
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
Very High Viscosity, Surface Insensitive Instant Adhesive
Our 3M™ Scotch-Weld™ Instant Adhesive CA50 Gel cures even on acidic surfaces (such as wood, paper, leather, and ceramic) and has a slower cure speed than traditional instant adhesives. These grade of adhesives combine high performance, excellent adhesion and temperature resistance with instant adhesive speed providing you with differentiated capabilities for your most difficult thin bond line applications. 3M™ Scotch-Weld™ Instant Adhesives provide you with differentiated capabilities for your most difficult thin bond line applications.
Used on many non-sag vertical applications
What are Instant Adhesives?
Instant adhesives are cyanoacrylate based formulas that are strong, fast-acting adhesives used in industrial and household applications. In general, they are an acrylic resin that rapidly polymerizes in the presence of water (specifically hydroxide ions), forming long, strong chains, joining the bonded surfaces together. Cyanoacrylates typically have a short shelf life. As a liquid, cyanoacrylate consists of monomers of cyanoacrylate molecules. Depending on the intended application or to facilitate easy handling, a cyanoacrylate adhesive may be formulated with an ingredient such as fumed silica to make it more viscous or gel-like.
Because the presence of moisture causes the glue to set, exposure to normal levels of humidity in the air causes a thin skin to form within seconds, which greatly slows the reactive curing process. Because of this cyanoacrylate should be applied thinly, to ensure that the reaction proceeds rapidly and a strong bond is formed within a reasonable time. Instant adhesives from 3M apply right from the container and rapidly reach handling strength at room temperature. A single drop per square inch can bond many plastics, rubber, metal and more with tensile strength up to 5,000 psi.
