Polyurethane Combined Polyether for Spray Foam

Overview

This combined polyether is a fully formulated polyol component for rigid polyurethane foam applied by spraying for on-site insulation. It reacts quickly, bonds well to most substrates and forms a seamless insulating layer. It contains polyether polyols together with catalysts, foam stabilizers and blowing agents, and is foamed by mixing with polymeric MDI at the ratio given in the technical data sheet.

Also known as

Combined polyether; Polyol premix (polyol side of a two-component rigid foam system)
