Mercury 803 2K Poly Putty (Premium Grade), dense and very viscous composition that is used to level unevenness in the substrates. Chemically resistant to most chemicals, its physical properties are excellent and there is no softening phenomenon under moderate heat. It can be coated both thin and thick, depending on the user's requirements. Compared with the Standard Grade, Mercury 803 offers better adhesion, greater flexibility, better standability, faster curing time, and higher impact resistance. Cured film of Poly Putty is very strong and does not delaminate from its substrate even when bent at 90 deg. angle.
