Gorilla Glue is an American brand of polyurethane adhesives. Bostik is among the four top adhesives and sealants producers in the world. The strength of epoxy adhesives is degraded at temperatures above . Some "breakable" epoxy adhesives contain suspensions of AP. UV radiation is useful in preparing low-surface-energy polymers for adhesives. No synthetic adhesives or binders used in the manufacturing. It is also used in adhesives and plastics. Polyurethane is the basis for some construction adhesives in a caulking tube format. This system is useful for low viscosity fluids, inks, paints, adhesives, and biological fluids.
