Polymer Nation U-20 Pigmented WB Urethane Acrylic Hybrid
Product Overview
U-20 is a breakthrough technology combining urethane and acrylic characteristics to create a unique, zero-VOC water-based topcoat. By combining our hybrid urethane/acrylic resin with our proprietary aliphatic hardener blend we are able to create a high-solids, pigmented finish that will not yellow, maintains its existing sheen and passes 2500 MEK double rubs! It is manufactured in a gloss but the sheen can be reduced using an alternate hardener specially designed to produce a satin finish.
Uses and Benefit
U-20 is primarily used as a pigmented topcoat due to its unsurpassed UV, mar and abrasion resistance. It can be applied to floors and walls and adheres well to many substrates including concrete, gypsum, cement board, metals, vinyl, PVC and fiberglass. It can also be applied direct to concrete as a primer and topcoat.
