Series 1448

Vinester

Generic Type

Novolac Vinyl Ester

Common Usage

A high-build, vinyl ester lining with corrosion resistant graphite fillers. Use where silica free coatings perform best, such as high alkali environments, spent bleach solutions and hydrofluoric and fluosilicic acids, in elevated temperature conditions for both dry, fume and wet services. The graphite also provides good electrical conductivity and is a high wear finish.
