&Name: One-component polyurethane sealant One-component polyurethane sealant product is a one-component fast-curing polyurethane sealant/adhesive with long-lasting elasticity.
Storage period: Polyurethane sealant is stored in a ventilated and dry warehouse below ℃ for no less than 1 month. Storage and transportation: Packaging: / branch, branch / box; Toxicity: non-toxic Transportation: no hazard Product features: Same as all Good bonding with cement base materials, bricks, glazed tiles, metal wood and other building materials; Cured at room temperature, neutral, non-toxic, non-polluting, non-corrosive; Mildew resistant; Strong durability; Good wear resistance, tear resistance Crack and puncture resistance; Good weather resistance and waterproof performance; No bleeding, no sagging, can fill large gaps; Ready to use on site, no need to stir; Good compatibility with paints and coatings, excellent surface paintability; Rapid curing . Construction method Base surface treatment: Keep the surface clean and free of oil, dust, open water and loose particles. Paint, scum and other poorly adhered particles must be removed and the joints can be cleaned with compressed air. To add padding material to the joints, soft, round or flat polyethylene material should be used. Gluing: & Use protective tape on both sides of the seam & Embed filler material & Use polyurethane sealant with a manual or pneumatic gun to avoid introducing air, horizontal sealing can be done concavely with a spatula & If necessary, use clean water with a few drops of synthetic cleaning Smooth with the agent & remove the protective tape before the polyurethane sealant cures & clean tools immediately after application. Cured material can only be removed mechanically. Material usage: The following joint design rules are recommended: & Below the joint width, the width-to-depth ratio is: & Above the joint width, the width-to-depth ratio is: To ensure the correct width-to-depth ratio and provide a solid backing for the sealant At the same time, to prevent the seal from sticking to the bottom of the joint, closed-cell polyethylene backing strips should be used. Do not use oil or tar impregnated backing materials. &/The construction lengths of the polyurethane sealant in the package for joint sealing of different widths are as follows: about meters, about meters, about meters, about meters. Technical parameters: (Comply with C/Standard) Application scope Polyurethane sealant is mainly used in: waterproof sealed roofs of sanitary facilities, waterproof sealed windows and doors of underground engineering waterproof membranes, various curtain wall joints, dados, and walls other than glass curtain walls. / Caulking of floor joints, shutters, residential bridges, tunnels, culverts, water conservancy projects, etc. Construction expansion joints/moving joints Seam sealing of roofs and gutters Seam sealing of tap water pipelines Waterproofing of reservoirs, water tanks and shafts Sealing the joints of concrete buildings, sealing the joints of cement concrete roads, bridges, and airport runways. & & If you are doing a waterproofing project, you must be eager to find a suitable product.
