Overview
Built for the job.
1K HS clear is a high solids clearcoat, perfect for refinishing small accessories, door jambs, underhoods, inner panels and new part cut ins.
SEM® 40913 1K HS Clear is a high-solids (12.8% solids) semi-gloss aerosol clearcoat designed for rapid topcoat applications in automotive refinishing. It provides a durable, high-shine finish on e-coat, OEM primers and compatible plastics, making it suitable for final coating of body panels, trim pieces and aftermarket components.
Each 20 oz can delivers approximately 23.4 sq ft at a film thickness of 1 mil, ensuring efficient coverage with minimal overspray. The formulation offers a fast flash time due to its low flash point of -42 °C, allowing quick handling and reduced cycle times in high-throughput shop environments. Compatibility with e-coat, OEM primers and selected plastics provides flexibility across multiple substrate types.
Use in a well-ventilated area and observe standard PPE: eye protection, chemical-resistant gloves, protective clothing and an appropriate respirator. The product is classified under several GHS hazards (acute toxicity, flammable gas, skin corrosion, etc.) and carries H-statements H222, H280, H315, H317, H319, H335, H336. Follow first-aid procedures as outlined in the SDS for inhalation, skin or eye exposure.
