MOR-FREE™ L75-164

A 100% solids, solvent-free, two component polyurethane adhesive system with a viscosity of 2,500-3,500 cPs.




Product Overview

Mor-Free™ L 75-164 is a two-component polyurethane adhesive system that is solvent-free and 100% solids, that can be applied at room temperature. As the reactivity of Mor-Free L 75-164 is high, the laminates can generally be further processed in as little as six hours. The chemical curing is generally completed within 3 days using C-411 co-reactant or 5 days using C-132-2 at room temperature (72 °F).
