Polyaspartic polyurea waterproof coatings are high-performance materials characterized as two-component, slow-curing, and high solid content. These polyurea materials are convenient and efficient to apply, offering advantages such as high weatherability, tensile strength, elongation, abrasion resistance, low water absorption, and strong substrate adhesion.

This hand-applied transparent waterproof material is not harmful to the body. This two-component, weather-resistant material is a type of polyaspartic ester polyurea coating. Its film does not discolor under UV light or form chromogenic groups, avoiding the yellowing and UV instability of aromatic isocyanate polymers. This aliphatic decorative material cures slowly and performs exceptionally.

Polyaspartic Polyurea Waterproof Coatings are suitable for long-term submerged environments and can be used for waterproofing applications in swimming pools, landscape pools, firefighting pools, and other areas expected to be immersed in water for extended periods. They are also appropriate for indoor waterproofing solutions in bathrooms, kitchens, balconies, as well as in other waterproof environments such as sauna shower rooms and SPAs. This product addresses the significant decline in performance of conventional water-based waterproof products on the market after prolonged water exposure. At the same time, it avoids the drawbacks of using polyurethane oil-based waterproof coatings in firefighting pools, drinking water pools, etc. Polyaspartic polyurea has now become a mainstream waterproof material worldwide.

Polyaspartic polyurea outperforms traditional waterproofing materials. It has excellent physical and chemical properties, including high tensile and impact strength, flexibility, wear resistance, anti-slip properties, aging and corrosion resistance. Polyaspartic polyurea coating adheres fully to the substrate, creating a seamless surface with superior integrity to prevent leaks.

Spray-applied polyurea is an elastomeric substance formed by the reaction of an isocyanate component (known as Component A) with an amine compound (Component R). The chemical reaction between these two components is extremely rapid, gelling in 5 seconds and achieving walk-on strength within a minute. If applied manually, the material would finish reacting before application is complete. Therefore, it requires professional equipment and must be applied under high-temperature and high-pressure conditions.

Polyurea waterproofing technology integrates advanced materials, facilities, and processes. It represents a significant advancement over traditional construction techniques and is currently one of the most advanced waterproofing technologies worldwide.
