Overview
Built for the booth.
A cost-effective solution to the European topcoat. A medium solids European clearcoat that doesn't skimp on performance and delivers on dry times to turn jobs around fast.
USC® 7415-25 Medium Activator is a 2.5 L liquid hardener formulated for use with US Chemical's 7400™ Euro Value Clearcoat (4.4 VOC). It provides the necessary activation chemistry to achieve optimal cross-linking in clearcoat applications, delivering consistent finish quality on e-coat and plastic substrates.
Key performance data include a pot life of 2 hours at 72 °F (22 °C), allowing ample working time for large panels. The activator delivers coverage of approximately 600 sq ft per mil of clearcoat, supporting efficient material usage. Its compatibility with e-coat and plastic substrates ensures reliable adhesion and durability across common automotive body shop repairs.
Safety handling requires standard PPE: eye protection, chemical-resistant gloves, protective clothing, and a respirator in adequately ventilated areas. The product carries a "Warning" signal word and is classified for acute toxicity, aspiration hazard, carcinogenicity, and other health risks; follow all SDS recommendations for first aid and exposure control.
