Jiangsu industry PUR glue direct selling industry in jiangsu PUR adhesive direct toxic. Oily coating adhesive is oily solvent ( Toluene, DMF, butanone, etc. ) As a solvent, dissolve or polyurethane acrylate. Its advantage is good film forming, good color fastness, PU can stick hot glue, is the current commonly used coating glue. Defect is due to the use of the oily solvent, so environmental protection lacking a bit, especially now that oil prices, oil solvent prices soaring all the way, most of the coating glue due to the cost is too high, so use more bad of the oily solvent, leading to environmental protection is not up to standard, in addition with the national environmental standards to further improve, so for environmental requirements of the coating adhesive is higher and higher. Flammable, encounter high fever, has caused the burning flame, strong oxidizer. It on the glass, aluminum alloy, galvanized steel, stainless steel and other materials have good adhesive properties. Hot melt adhesive is a kind of plastic adhesives, to a certain temperature range with the temperature change and change its physical state, and chemical properties unchanged, its non-toxic tasteless, environmentally friendly chemical products. Is the use of hot melt glue by heating the hot melt adhesive, hot melt adhesive machine melt glue after become a kind of liquid, by hot melt adhesive machine hot melt rubber hose and hot melt glue gun, to be adhesive surfaces, hot melt adhesive cooling after completed the glue. Allowable concentration of 100 PPM in the air. Can use a variety of hot melt adhesive lining cloth processing, almost all types of hot melt adhesive can be used, with much is ethylene - Vinyl acetate ( EVA) Hot melt adhesive, polyamide hot melt adhesive and high-pressure polyethylene ( HDPE) Hot melt glue powder, and different USES of hot melt adhesive and processing methods are also different. Water-based glue process characteristics (1) using water-based glue, in line with the shoe industry, a long-term trend in brands actively, water-based adhesive has been widely used all kinds of shoe factory, water-based glue quality gradually progress and stability; Jiangsu industry PUR glue selling in light, heat, ionizing radiation and easy polymerization in the presence of catalyst. The use of hot melt adhesive technical indicators are as follows: appearance: white is slightly yellow granular or stick. (2) use water-based glue will lead to environmental protection, health, save energy, save cost of equipment and manpower, fire safety, etc; Search the public number: WPU - 88 China adhesive platform 8 (3) cost: water-based glue consumption is 1/3 of solvent-based glue, if the water 3 times of unit price shall not exceed the solvent adhesive, replace solvent-based adhesive with water-based glue will not increase costs, as oil prices rise, the cost of the solvent adhesive is bigger than water-based glue rise, in the long run, water-based glue process cost lower than that of solvent adhesive process. Jiangsu industry PUR glue selling such as water soluble or decentralized hot melt adhesive, hot melt sealant, hot melt pressure sensitive adhesive and so on. 2. Water-based glue is introduced acrylate pressure-sensitive adhesive is acrylate, acrylic acid and other functional monomer, by way of solution polymerization or emulsion polymerization, free radical polymerization have been the result. Due to its extremely low water vapor transmittance, it can form a with elastic sealant excellent resistance to moisture system. Jiangsu industry PUR glue selling water-based polyurethane with water as solvent, no pollution, safe and reliable, excellent mechanical properties, good compatibility, easy modification.
