This sealant is a solvent-free and one-component at room temperature curing product. It is paste, can be squeezed or daubed. It has the characteristic of sag resistance, embedded in vertical seam and seam roof not flowing. After Curing it will be like rubber and to be elastic.

It also can show the good adhesively with metal, rubber, wood, ceramics, glass, cement components etc. Sealant is a materials used to fill the gaps, holes, connectors, joints, etc.) With the two big functions both adhesive and seal.

Applications

Polyurethane sealant is widely used in civil engineering and construction, transportation and other industries:

1.The application in the field of architecture: gap of the doors, windows, and glass to be filled.

2.Applications in the civil engineering: highways, Bridges, airport runway and other sealing caulking;

3.Applications in the automotive, seal need for windows assembly (mainly windshield).

Characteristic

1.Wide range of adjustable performance, strong adaptability;
2.good performance of Wear-resisting;
3.Mechanical strength;
4.good performance of adhesive;
5.Good elasticity, excellent resilience, and used for dynamic joint;
6.good flexility in Low temperature;
7.service lifelong to be of 15 ~ 20 years;
8.good performance of oil resistivity;
