One-component polyurethane sealant

One-component polyurethane sealant Product description: PU Building Sealant is a novel moisture curable one-component sealant construction sealant that in addition to having a polyurethane sealant excellent properties, but also by the introduction of a silane coupling agent improved bond strength to various substrates, resistance to heat aging resistance and storage stability. It represents the current era building sealant world advanced level. Product Features of concrete, masonry, metal products, plastic products have good adhesion. Does not contain toluene and volatile solvents, non-toxic, are green products. High flexibility, high tensile strength, cyclic deformation can be adapted to larger structures waterproof seal. At room temperature table dry fast, four hours is dry, help shorten the construction period. Scope settlement joint, expansion joints, construction joints, between reservoirs, swimming pools, balconies, door frames, bathroom, wall pipes, gas pipes and water pipes and other parts of the seal. Airport runways, underground parking, playgrounds, sidewalks, bridges, squares, tunnels, highways and other joints sealed. Construction Guide with a wire brush, gray knife to slit trench debris and floating ash clean up. Deeper joints should be filled PE foam for the backing material can also be used to make other plastic or wood backing, in order to reduce waste sealant. Dispensing of a thickness of 1.5 times the width of the slit, for example, when the slit width 2cm thickness of the sealant injection 3cm. Dispensing with special glue gun, glue gun nozzle when injection should be evenly slow-moving, ensure seams filled with infill to prevent air bubbles space left. Notice shall rain construction, construction of surface shall have clear water. Within 48 hours after application to seal the seams are not allowed displacement. Construction should avoid too dry place, away from sources of ignition. Packaging and storage Packaging: factory packaging 0.5kg / support. 20 / box Storage: The product is non-flammable materials, transportation and storage process to prevent sunlight, try low temperature storage, anti-rain, anti-extrusion collision. The product under normal storage conditions shelf life of nine months.
