May cause allergic skin reactions, such as contact with skin, rinse with warm water, such as eye contact, it certainly is stored at 10 ~ 25 ℃ dry and cool environment, avoiding direct glare, prohibiting contact with warm air and alcohol solvent. PUR hot melt adhesive should be flushed with water, or go to the hospital for treatment. PUR hot melt adhesive after opening into use within three minutes. Wear protective gloves when operating and protective glasses, avoid inhalation of vapors and mists. If not specify the intended use is prohibited into the environment, in accordance with local and national regulations for disposal of the goods or containers. PUR Hot Melt fire fighting methods: ordinary suitable extinguishing agent. Please ask for PUR hot melt adhesive Safety Data Sheets to manufacturers or vendors. The above is a brief introduction PUR hot melt adhesives, need detailed information, please go gold Shengwei Guan network download. The following is the PUR hot melt adhesive informal information purposes only. PUR hot melt adhesive is heated to a certain temperature after having melting characteristics. Colloid after melting has good fluidity and adhesiveness, moisture curing after cooling the glue into a translucent gel, both adhesive property and toughness, and good electrical insulation and moisture resistance. After curing PUR hot melt adhesive while also softened by heating the repair again, so there is a reversible performance. Products are usually provided in the form of plastic bottles, plastic bottle through the dispenser and heated to the melting of PUR hot melt adhesives. Then glue on the material. Dispenser mainly by triaxial structure, the heating system, temperature, gas control and other components. Wherein the heating chamber by the PTC heating elements for PUR hot melt adhesive is heated, temperature control, the colloidal gel into a liquid flowing from the needle. JSW dispenser AC 220V power supply, make bonding method is very simple, continuous sizing its operation after power-heated, melted plastic bottles after PUR hot melt adhesive in the heating chamber, the needle is applied to the bonding site moisture cured bonding colloid formation. PUR hot melt adhesive products introduced in the early stages, if the product is an alternative to traditional products, it will be faced with a higher initial cost of the problems, such as new energy PUR hot melt adhesives to replace the traditional. Currently, the new energy products, the cost is higher, the performance is not as conventional PUR hot melt adhesive, so we are faced with a difficult problem of market entry. Finally, there is the whole consumer environment relatively large obstacles. Such as new energy PUR hot melt adhesive dispensing facilities inadequate, will restrict new energy PUR hot melt adhesive applied on a large scale. This is a feature of the market. Ali adhesive products survey found that many manufacturers do not know how to react to choose to meet the new standard adhesive products, I do not know how to determine whether the product is within the range of PUR hot melt adhesive in the bonding of the standards required. In this regard, the Ministry of Industry PUR hot melt adhesive standards compliance testing center recently conducted an industry energy efficiency level detection, Jinsheng Wei submission two PUR hot melt adhesive, the results show the effect of censorship in the bonding level above all, to environmental protection, bonding a standard accounted for 99.8%.
