About the product
Product Overview
U-91 Combines our robust, proprietary polyol resin blend with our flexible aliphatic hardener to create a felxible, urethane with unique performance characteristics. U-91 is a 100% solids, low odor, low viscosity urethane that provides amazing flexibility, toughness, and UV resistance.
Uses and Benefits
U-91 is primarily used as a clear grout coat over EPDM filled systems, due to its unsurpassed UV stability, flexibility and abrasion resistance. It can also be used as a component in flexible wall systems and padding. It adheres well to many substrates including concrete, gypsum, cement board, metals and fiberglass. Suitable topcoats for U-91 are as follows: F-series polyaspartics, U-51 MCU, U-21 2K WB urethane, or SP-series polyaspartics.
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
