U-51 Clear Aliphatic Moisture Cure
About the product
Product Overview
U-51 is a non-yellowing, single component, aliphatic moisture cure urethane coating with excellent wear, stain resistance and adhesion properties. When used as a topcoat over conventional coatings, U-51 provides UV-light protection and dramatically improved abrasion resistance.
Uses
U-51 is primarily used as a clear topcoat due to its unsurpassed UV, stain, 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 sealer and topcoat.
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
