Polyurethane joint sealer / sealant is one component, designed especially for joint sealing and elastic bonding for waterproof work. The one-component polyurethane sealant is a paste room temperature (RT)curing type product. The cured sealant is black and bright after solidification, and has high tensile strength and cohesiveness. It will expand slowly when it encounters water and moisture, and achieve the effect of stopping water leakage. it is anti-inflated, one-component water-swellable, moisture-curing, elastic sealant. It is based on a polyurethane prepolymer and contains a urethane paste with a special grafting technology. After curing, it has a dual sealing and water stopping mechanism that expands in volume when it meets water and seals elastically.

Application Scope

This product is mainly suitable for waterproofing of construction joints (including post-casting belts), deformation joints and embedded components of projects such as underground engineering of industrial and civil buildings, municipal tunnels, protective engineering, mountain and underwater tunnels, underground railways, sewage treatment ponds, and Treatment of leakage in existing projects.

Waterproofing of construction joint, pipeline and concrete iron in wall or cement board, Surrounding the concrete iron or joint and inner joint of cable
