Polymer Nation SP-71 Medium Speed >96% Solids Polyaspartic
Product Overview
Polymer Nation SP-71 is a medium-speed, clear, high-build polyaspartic formulated from proprietary aspartic esters and an ISO blend. Its ultra-high-solids formulation (>96%) and low viscosity provide medium working time with fast dry time; the coating resists yellowing and chalking.
Uses and Benefits
SP-71 is used primarily as a clear topcoat for UV and abrasion resistance. It can be applied to floors and walls and adheres to concrete, gypsum, cement board, metals, and fiberglass.
