Material Notes:
Chemglaze® M331 is a two package, ASTM D-16 Type IV elastomeric polyurethane coating. Cured films produced from this coating are tough, flexible, and resistant to erosion, abrasion, and impact. These films provide excellent tensile and elongation properties, and prevent corrosion of metal substrates in aggressive environments.Basic UsesChemglaze elastomeric polyurethane coatings function especially well in abrasive environments. With their inherent flexibility, corrosion resistance and energy absorptive properties, these coatings are used in the railroad and mining industries to protect metallic substrates. Chemglaze elastomeric coatings accommodate thermal expansion and contraction as well as structural motion. These elastic properties make them useful in protecting spray applied polyurethane foam insulation on storage tanks and reactor vessel walls.These coating qualify under military rain erosion coating specification MIL-C-85322.All information provided by Lord.
