Product Overview
Sprayed polyurea elastomer is a solvent-free, two-component, mechanically sprayed polyurea elastomer material. The material is cured on site by semi-prepolymers, end amino polyethers, delayed diamine chain extenders and other raw materials. Its ratio of component A to component B is 1:1, with component A at 220 kg per barrel and component B at 220 kg per barrel.
Application scenarios
Sprayed polyurea elastomer coatings are widely used in chemical corrosion protection, pipeline corrosion protection, waterproofing engineering, mine wear resistance, protective lining, sports engineering, industrial floors and buoyant materials. In high-end manufacturing fields such as aerospace and automobile manufacturing, it is also used for its lightweight, high-strength, sound insulation and noise reduction. In the future, we will pay more attention to environmental protection performance and develop coating materials with special functions.
