3M™ Scotch-Weld™ Super Fast Instant Adhesive SF100 is a low viscosity, very fast curing instant adhesive. Our super fast instant adhesives rely less on surface moisture for cure speed than standard cyanoacrylates.
We designed this instant adhesive to join together difficult-to-bond plastics and rubbers, acidic and/or contaminated surfaces such as woods, leathers, cardboard, and oily surfaces. Low viscosity helps the adhesive quickly flow and create a thin layer that bonds in just a few seconds.This fast acting cyanoacrylate can be used for a super fast cure in high speed production applications.
What are Instant Adhesives?
Instant adhesives are Cyanoacrylate based formulas that are strong, fast-acting adhesives used in industrial, medical and household applications. In general, they are an acrylic resin that rapidly polymerises in the presence of water (specifically hydroxide ions), forming long, strong chains, joining the bonded surfaces together. Cyanoacrylates are sensitive to moisture. Excess exposure to moisture may reduce its shelf life.
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.
