Product Description

Product Description

Product descriptions         ,

When the vehicles got collision in the driving process, the vehicle body can easily get damaged and bring risks to the people inside the car. Therefore, it is important to choose a explosion protection material to protect the vehicles. STWD Urethane Co., USA developed explosion protection high strength coating, which has excellent performance of being tough, abrasion resistance and impact resistance. It has been widely used on American armored vehicles,  special industry escort vehicles and sport utility vehicles

Characteristics             
The product has high reactivity, fast cure, can be sprayed forming on any bent, slope and vertical surfaces without sagging. Surface granulation, nice and feel comfortable. The coating film is dense, seamless, bond well with substrate that greatly increase the adhesive strength. It has excellent explosion protection, impact resistance and anti-collision, to protect the car body and decrease the damage of external force. Spray along with STWD polyaspartic anti-aging topcoat to protect the car body from color-changing, good decoration and safe.
