LD 331
LD 331 is a two-component polyurethane polymer used for waterproof and rock reinforcement. Its high performance of adhesive force and good mechanical and physical properties ensure that it has strong bonding with rock mass. The reaction will expand when it meets water, quickly and effectively to prevent water ingress. Its flexibility can bear the ground movement; Moreover, it has strong anti-permeability, anti-wear, anti-impact and anti-aging properties, so as to achieve the purpose of long-term stable formation, sealing water cracks and channels.
