General Description
UVALAM EST-FL40 is a two part 1:1, toughened, medium viscosity, industrial grade epoxy adhesive with a medium working life.
Once mixed, the two component epoxy cures at room temperature to form a flexible, gray bonding line with excellent resistance to shock and impact.
When fully cured, the epoxy is resistant to a wide range of chemicals and solvents, and acts as an excellent electrical insulator.
