One component polyurethane sealant

Product Description   The sealant is a solvent-free single-component room-temperature curing sealant. The sealant is in the form of paste and can be extruded or smeared. It has anti-sag property, and the vertical seam and top seam are not filled. The cured adhesive layer is rubber-like and flexible. Adhesion to metal, rubber, wood, cement components, ceramics, glass, etc. Sealant is a material used to fill gaps (holes, joints, joints, etc.), and has both the functions of bonding and sealing.

Application  Polyurethane sealant is widely used in civil construction, transportation and OTHER industries:
1. Application in construction-filling and sealing of doors, windows, glass, etc .;
2. Application in civil engineering-caulking sealing of highways, bridges, airstrips, etc .;
3. Application in automobiles-assembly and sealing of windows (mainly windshield glass).
Sealant is a material used to fill gaps (holes, joints, joints, etc.), and has both the functions of bonding and sealing. Polyurethane sealant, silicone sealant and polysulfide sealant constitute the three major varieties of sealant. Feature  1. Wide range of adjustable performance and strong adaptability;
2. Good wear resistance;
3. High mechanical strength;
4. Good bonding performance;
5. Good elasticity and excellent recovery, can be used for dynamic seams;
6. Good flexibility at low temperature;
7. Good weather resistance, service life up to 15 ~ 20 years;
8. Good oil resistance;
9. Resistant to biological aging;
10. The price is moderate.   Advantages   "One-component" is mainly relative to "two-component". There is a two-component polyurethane adhesive. When using it, it is necessary to mix and seal the A and B components uniformly in proportion; It is used directly, which is convenient, concise and easy to construct. "Moisture curing" means that the one-component polyurethane glue is cured by the reaction of water vapor in the air, and reacts with the active groups on the surface of the substrate to play a bonding role. One-component polyurethane glue can be used in drinking water projects, and has passed the authoritative test. Packaging & Shipping   Company Information   Contact Information
