Description
Tectyl 127CG Gray is a solvent-based, gelled calcium sulfonate compound manufactured by Daubert Chemical Company. This specialized corrosion preventive coating is formulated with mineral spirits to provide excellent weathering and corrosion protection, abrasion resistance, and sound dampening for industrial applications. When applied, Tectyl 127CG Gray forms a firm, non-tacky, wax-like protective film with a distinctive gray/aluminum color, making it suitable for manufacturers and industries that prefer this alternative to traditional black undercoatings. The product is specifically recommended for use in the transportation industry as an undercoating and sound deadener, while also possessing dielectric properties that prevent galvanic corrosion between dissimilar metals.
