1. One component polyurethane sealant is a solvent-free one component room temperature curing sealant. The sealant is in paste form and can be extruded or applied for construction. It has sag resistance, and the embedded vertical joints and top joints do not flow. The cured rubber layer is rubber like and elastic. Adhesion to metal, rubber, wood, cement components, ceramics, glass, etc. Sealant is a material used to fill gaps (holes, joints, seams, etc.), which has two major functions: bonding and sealing.
2. One component polyurethane sealant application industry
Widely used in civil construction, transportation and other industries:
Application in architecture - filling and sealing of doors, windows, glass, etc;
Application in civil engineering - caulking and sealing of highways, bridges, tunnels, aircraft runways, etc;
Application in automobile - assembly and sealing of windows (mainly windshield).
Sealant is a material used to fill gaps (holes, joints, seams, etc.), which has two major functions: bonding and sealing. Polyurethane sealant, silicone sealant and polysulfide sealant constitute the three major varieties of advanced sealant at present.
3. Characteristics of single component polyurethane sealant: wide performance adjustable range and strong adaptability; Good wear resistance; High mechanical strength; Good adhesion; Good elasticity, excellent resilience, and can be used for dynamic joints; Good low-temperature flexibility; Good weather resistance, service life up to 15-20 years; Good oil resistance; Biological aging resistance; The price is moderate.
4. Advantages of single component polyurethane sealant: "single component" is mainly relative to "two-component". There is a two-component polyurethane adhesive. When using, components A and B need to be mixed evenly in proportion to achieve bonding and sealing effect; The single component is directly used, convenient, simple and easy to construct. "Wet curing" means that the one component polyurethane adhesive is cured by using the micro amount of water vapor in the air to react with the active groups on the surface of the substrate to play a bonding role. Compared with traditional silicone adhesive, polyurethane adhesive has more than 3 times of high elongation and more than 2 times of bonding strength. One component polyurethane adhesive is harmless after complete curing, and can be used in drinking water engineering. It has been tested.
One component polyurethane sealant is made by introducing new technology from abroad and using imported polyurethane and other raw materials. This product has the characteristics that it can absorb moisture from the air after coating and solidify into a film, thus overcoming the defect that two-component polyurethane waterproof coating needs to be mixed on site before use. This product is easy to construct, does not contain coal tar pitch, and is harmless and tasteless. It is widely used in waterproof engineering and is an ideal environment-friendly waterproof material. Since the viscosity of the prepolymer is moderate, it does not need to be diluted with the solvent of the agricultural production system. It can be applied at 90% of the relative temperature. The development of one component moisture curing polyurethane waterproof coating is convenient in construction, pollution-free, environmentally friendly and reasonable in price, which is the development direction of polyurethane waterproof coating.
Product characteristics
1. There is no coal tar, no flammable and explosive substances, no need to provide special security measures for the storage, transportation and construction site of the coating, and it is an environmental protection product to reduce pollution due to the small reactive odor.
2. Single component construction, convenient operation and safe construction can overcome the shortcomings of uneven mixing of two-component materials and affecting product quality.
3. It can be constructed on a wet base surface, and has good acid resistance, alkali resistance, heat resistance, cold resistance (- 30 ℃~90 ℃), and aging resistance.
4. It has good integrity and forms a tough elastic sealing layer after film forming. The common base surface can meet the required waterproof requirements in one construction, and can be added with pigment to make a colorful coating with decorative effect.
5. It has strong bonding force and can bond with different materials such as concrete, masonry, wood, glass, metal, rubber, etc.
6. In the process of production and construction, there is little odor and environmental pollution on the site. The coating can be applied directly at room temperature when necessary
The surface of waterproof treated base course does not need to go through the process of measurement, matching and mixing, and the operation process is very simple.
7. The waterproof film formed after curing has high tensile stress, high breaking elongation, good elasticity, stable performance and excellent durability
8. Liquid construction, room temperature curing, short solidification period, strong adhesion, high waterproof and impermeability.
9. High elongation, cold and heat resistance, corrosion resistance and aging resistance.
Scope of application
1. Waterproof works for various flat and inclined roofs, color steel roofs, gutters, canopies, etc. of buildings and irregular roofs.
2. Waterproof works of underground buildings, such as basement concrete floor, internal and external walls, retaining walls, tunnels, pits.
3. Waterproof works of various buildings, such as toilets, kitchens, swimming pools, flower beds, sluice floors, construction joints, expansion joints, through walls
Pipe, sinkhole, court, runway, etc.
4. Bonding anti-corrosion: it can be used as external anti-corrosion, anti-corrosion floor and anti-corrosion tank of pipeline.
