Premium wax/asphaltic based, corrosion preventive underbody coating
Tectyl 121-LV is a filled, solvent cutback wax/asphaltic base, thixotropic, corrosion preventive compound.
Tectyl 121-LV is suitable for the complete undercoating of undersides of autos, trucks, buses, truck trailers, camp trailers, heavy construction equipment and cargo containers.
Tectyl 121-LV is very suitable as a coating in industrial constructions of ovens and chimneys, where high temperatures and in between periods under the dew point can occur.
Tectyl 121-LV dries to a firm, black, resilient, tough and abrasion resistant film.
