One-component polyurethane sealant is a solvent-free one-component that can solidify under indoor temperature. The sealant is creamy and can be extruded or applied. There is resistance to sagging, embedding vertical joints.
One-component polyurethane sealant is a solvent-free one-component that can solidify under indoor temperature. The sealant is creamy and can be extruded or applied. There is resistance to sagging, embedding vertical joints.
The solidified layer is rubbery and elastic. It can be adhesive to metal, rubber, wood, cement components, ceramics, glass,etc. With functions of bonding and sealing ,sealant is widely used to fill the gaps like holes and joints, etc.
(1)good bonding with with all the cement substrate, brick, glazed tiles, metal wood and other building materials;
(2) solidify at room temperature with good specifications like neutral, non-toxic, non-polluting, non-corrosive;
(3) anti-mildew;
(4) strong durability;
(5) good wear resistance, tear resistance, anti-puncture;
(6) good weather resistance and waterproof performance;
(7) with no flow, no sagging, it can fill a larger gap;
(8)It can be used on-site without mixing;
(9)It has a good compatibility with paint and it can be well painted on the surface;
One-component polyurethane sealant is widely applied to:
(1) construction - doors and windows and glass,etc ;
(2) civil engineering- highway, bridges, and airstrip,etc;
(3)car - the windows (mainly windshield) .
