Product Overview
Handmade polyurea elastomer is a solvent-free, two-component, hand-brushed polyurea elastomer material. The material is cured on site from semi-prepolymers, end amino polyethers, delayed diamine chain extenders and other raw materials to form elastic polyurea floor materials. The ratio of component A to component B is 1:1, where component A weighs 18kg and component B weighs 18kg.
Application scenarios
Widely used in industry, commerce, public facilities, sports venues and other fields. Its characteristics include wear resistance, pressure resistance, impact resistance, and chemical corrosion resistance, and is suitable for production environments, commercial places, parking lots, airports, stations, sports venues, etc. Polyurea flooring is also used for waterproof and wear-resistant projects on roofs, bridge decks, platforms, platforms, parking garages, as well as waterproof and wear-resistant projects on balcony surfaces.
