1 results about "Epoxy putty" patented technology

Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application. They are stored until use as two components of clay-like consistency. Kneading the two components into each other creates an exothermic chemical reaction that activates the substance for use by catalyzing an epoxide polymerisation reaction. Unlike many other types of glues, an epoxy adhesive can fill gaps and even be molded into a structural part. Some makers claim in advertising that one can drill and tap their cured products, and that they quickly cure "hard as steel" (as measured by Shore rating), though they are much weaker than steel in tensile strength and shear strength.
