PPG Industries’ industrial coatings business has published an informational guide about ENVIRON MCL coatings, an environmentally-friendly, water-based coating for application on metallic coating lines over GALVALUME coated sheet steel and hot-dipped galvanized metal.
Environ MCL products provide a permanent coating that is superior to temporary anti-fingerprint coatings available on the market and extends the life of buildings by offering lasting aesthetics with enhanced solar reflectance (SR), ultraviolet (UV) protection and corrosion resistance. Available as a clearcoat or in a selection of colors, Environ MCL coatings have a minimum SR capability of 70, which enables them to reduce energy costs and improve comfort in metal building structures.
The guide includes performance specifications with data for dry film thickness, post-cure pencil hardness, solar reflectance, salt-spray and humidity resistance, accelerated weathering, and outdoor exposure.
As a water-based product with low VOC (volatile organic compound) content, Environ MCL coatings protect the environment by encapsulating zinc from the metal substrate to eliminate toxic runoff into the water supply. The coatings also can be applied on mill coatings lines, which can reduce costs by eliminating the need to send metal to a coil coater for processing.
Typical exterior applications for Environ MCL coatings include metal roofing, agricultural buildings and shade and shelter structures. The coatings are also suitable for interior uses such as ceiling grids, structural steel, linear panels and roof decking.
