1.Description

PS600H is a material characterized by its high crosslinking density and moderate elasticity, along with exceptional wear resistance. During vehicle collisions, the body is susceptible to damage, which can pose serious risks to occupants. Therefore, selecting a reliable explosion-resistant material for vehicle protection is crucial. To address this need, we have developed a high-strength, explosion-protective coating that offers outstanding toughness, abrasion resistance, and impact resistance. This coating has been widely applied in armored vehicles, police cars, special-purpose escort vehicles, and sports utility vehicles.

2. Characteristics

PS600H offers high reactivity and fast curing properties. It can be sprayed onto curved, sloped, or vertical surfaces without sagging.The resulting surface exhibits a granular texture that is visually appealing and pleasant to the touch. The coating forms a dense, seamless film with strong adhesion to the substrate, significantly enhancing bond strength. It provides excellent explosion protection, impact resistance, and collision resistance, helping to safeguard the vehicle body and reduce damage from external forces. When sprayed in combination with a polyaspartic anti-aging topcoat, it effectively prevents color fading, ensures an attractive appearance, and enhances overall safety.
