Overview
Built for the booth.
U.S. Chemical and Plastics 10 universal urethane clear coat offers excellent performance and appearance at an economical price. 10 universal clear coat flows out to a smooth, durable finish with excellent gloss. USC® 10 Clear is ideal for spot, panel, multi-panel and overall refinishing.
USC® 10‑1 10™ Universal High‑Build Urethane Clear Coat is a single‑component, high‑performance clear coat formulated for automotive refinishing. It is designed for use on e‑coat and plastic substrates, providing a durable, high‑gloss finish that meets the demands of collision repair and custom paint work.
Mixed at a 4:1 volume ratio, the clear coat offers a pot life of 2–4 hours at 72 °F (22 °C) and a flash time of 8–10 minutes between coats, allowing ample working time while maintaining rapid build‑up. Coverage is rated at 480 sq ft per gallon at a 1.0 mil film thickness, delivering efficient material usage and consistent thickness across large panels.
Handling requires standard PPE: eye protection, chemical‑resistant gloves, protective clothing, and a respirator. Use in a well‑ventilated area and observe the “Warning” signal word due to acute toxicity, flammability, and other listed hazards.
