Product Description
STWD9513 is a 100% solids aromatic spray polyurea elastomer. Due to the frequent traffic of loading and discharge of cargo, the truck container is easily damaged by the heavy impact, collision and wear strength. The normal coatings can decorate the truck bed rather than protect it effectively. The bed liner of a new truck is usually destroyed in less than 1 year after application. Spray polyurethane elastomer innovated a brand new solution for the truck bed liners protection. It has been widely applied in the automotive manufacturing industry in the US with perfect reputation.
Product features and advantages.
