L-21 Novolac Epoxy Liner
About the product
Product Overview
L-21 is a high viscosity, nonylphenol-free, Novolac resin (not a Bis F masquerading as a Novolac). It has been designed as a chemical resistant liner for higher levels of protection than our standard Bisphenol A epoxies.
Uses
L-21 is most often used as a high-build finish coat in areas that require high heat and/or a high degree of protection from chemical attack. It provides protection from acids, caustics and solvents. For specific chemical resistance information contact Lab@polymerNation.com
Preparation
The coating installer should fully read and understand ICRI310.2R-2013 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer. If unsure as to the level of preparation needed contact Polymer Nation at techservice@polymernation.com
