Product Performance Overview
The Tianshi series Polyurea is a third-generation polyurea protective material, made from modified isocyanate prepolymers and polyaspartic acid esters as core raw materials. It reacts rapidly on-site to form a seamless coating. This product features excellent waterproof, moisture-proof, and weather-resistant properties, making it a high-performance polyurea waterproofing system material designed for complex engineering environments. It effectively prevents water vapor penetration, ensuring long-term dryness and stability of building structures.
