Specifications of one-component polyurethane sealant: Density per box: . tons Shelf life: months
Overview Editor This sealant is a solvent-free one-component room temperature curing sealant. The sealant is in the form of a paste and can be applied by extrusion or smearing. It is anti-sag, and the vertical seams and top seams are filled without bleeding. The cured glue layer is rubbery and elastic. It has adhesion to metal, rubber, wood, cement components, ceramics, glass, etc. Sealant is a material used to fill gaps (holes, joints, seams, etc.) and has both bonding and sealing functions. Application Industry Editor Polyurethane sealants are widely used in civil construction, transportation and other industries: .Applications in construction&&Filling and sealing of doors, windows, glass, etc. Applications in civil engineering&&Caulking sealing of highways, bridges, runways, etc. .Applications in automobiles&&Assembly and sealing of car windows (mainly windshields). Sealant is a material used to fill gaps (holes, joints, seams, etc.) and has both bonding and sealing functions. Polyurethane sealant, silicone sealant, and polysulfide sealant constitute the three major varieties of high-end sealants at present. Features editor. Wide adjustable performance range, strong adaptability. Good wear resistance. High mechanical strength. Good bonding performance. Good elasticity, excellent recovery, can be used for dynamic joints. Good low-temperature flexibility. Good weather resistance. The service life is up to ~ years. It has good oil resistance. It is resistant to biological aging. The price is moderate. Advantages: "Single-component" is mainly compared to "two-component". There is a two-component polyurethane glue. When using it, you need to mix component B and B evenly in proportion to achieve bonding and sealing. The effect is that the single component can be used directly, which is convenient, simple and easy to construct. "Moisture curing" means that one-component polyurethane glue is cured by reacting with trace amounts of water vapor in the air, and reacts with active groups on the surface of the substrate to bond. Compared with traditional silicone glue, polyurethane glue has more than twice the high elongation and more than times the bonding strength. One-component polyurethane glue is non-toxic after complete curing and can be used in drinking water projects. It has been authoritatively tested. The water-swellable water-stop sealant provided by our company is a single-component, moisture-cured, solvent-free, water-swellable polyurethane waterproof sealant. It has the elastic water-stop of rubber and double waterproofing of its own volume expansion after swelling with water. Mechanism, good construction operability and base surface adhesion, it is an upgraded product of traditional waterstop strips and a leading solution for waterproofing of building joints
