Guangdong one-component polyurethane sealant company

Guangdong One-component Polyurethane Sealant Company
Single-component polyurethane sealant is a one-component water-swelling and moisture-curing elastic sealant independently developed by our company. It is based on polyurethane prepolymer and contains urethane paste with special grafting technology. After curing and forming, it has a dual sealing and water-stopping mechanism of volume expansion when exposed to water and elastic sealing and water-stopping. This product is mainly suitable for the waterproofing of construction joints including deformation joints of post-cast belts and embedded components in industrial and civil construction underground engineering, municipal tunnel protection projects, mountain and underwater tunnels, underground railway sewage treatment tanks and other projects, as well as the water leakage control of existing projects. .
Product Features
Good water-stopping effect. It has the dual water-stopping mechanism of elastic water-stopping of rubber and self-volume expansion sealing when exposed to water. Maximum water pressure resistance
Strong durability and low mass change rate. The water-swellable sealant contains urethane linking chains with special grafting technology, which will not cause loss of expansion elements during long-term use. At ℃ temperature, the theoretical life is years
