GP LB-7575 is an etherified bisphenol-A resin with free formaldehyde and free bisphenol-A contents of less than 0.1%. It is a low-color, heat-reactive phenolic resin solution in n-butanol used as a crosslinker for hydroxyl-containing polymers such as epoxies, polyesters, vinyls and acrylics. It can be emulsified into water-based epoxy resins and is designed to maximize chemical resistance.
