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

Mixing & Installation
Combine all of part A and B into a single container, large enough to accept the entire kit. Mix at 350 RPM for 2-3 minutes using an appropriate mixing blade and making sure not to introduce excessive air into the solution. Pour the entire content from the container onto the floor and follow normal squeegee and back roll techniques. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone.
