Chemlok 305-1/310-B Black Epoxy Adhesive
Two-component epoxy adhesive for waterworks assemblies
Chemlok 305-1/310-B Black adhesive is a general purpose, medium viscosity, two-component epoxy adhesive system used for bonding waterworks assemblies. It is NSF approved and environmentally recommended due to its solvent-free, non-flammable, and virtually odorless composition. The adhesive cures at room temperature, achieving handling strength in 8-16 hours and full strength in 24-48 hours. Faster curing times can be achieved with higher temperatures. Once cured, the adhesive can be filed, sanded, machined, and painted.
