2P-10 is a two-part, 10 second bond adhesive. Just apply the adhesive, spray with activator, and press together for a strong permanent bond. 2P-10 is available in four different viscosities:Jel for vertical surfaces where you want the glue to stay put. Thick for bonding porous surfaces like particleboard. Medium for smooth surfaces and filling cracks. Thin for nonporous surfaces like ceramics. Debonder is used to remove unwanted glue residue. Kit contains 1 oz. each of Jel, Thick and Medium Adhesives for bonding different surfaces, 2 oz. Activator for a fast permanent bond, and 2 oz. Debonder for removing glue residue. All in a plastic storage and travel case.
