Polymer Nation L-21 Novolac Epoxy
Polymer Nation 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 standard Bisphenol A epoxies.
Uses and Benefits
Polymer Nation 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.
