1. The water-based coating adhesive is made by emulsification of acrylic or polyurethane resin through special emulsification equipment with water as a solvent. Its biggest advantages are: variety, environmental protection, low price, many coatings now use water-soluble glue, such as: general water-soluble PA, water-soluble PU and film glue, oily wax feeling, color scraping paste and other functional pastes. Water-solubility, with its functionality, environmental protection, and low price, will be the direction of future coatings. The disadvantages are poor film-forming properties, poor washing fastness, and PU cannot be pasted with hot air glue.

     Oil-based coating adhesive is made by dissolving acrylic or polyurethane with oil-based solvent (toluene, DMF, butanone, etc.) as a solvent. Its advantages are good film formation, good fastness, and PU can be pasted with hot air glue, which is currently a commonly used coating glue. The disadvantage is that due to the use of oil-based solvents, there is a lack of environmental protection. Especially now that the price of oil has risen, the price of oil-based solvents has risen all the way. Most of the coating adhesives use relatively poor oil-based solvents due to the high cost, resulting in Environmental protection is not up to standard, and with the further improvement of environmental protection standards in various countries, the environmental protection requirements for coating adhesives are getting higher and higher.

     Hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, which is mainly made by mixing synthetic rubber, resin and rubber oil into a melted state and then coating it on a substrate such as tissue paper, cloth or plastic film. The new type of adhesive tape, low cost is its biggest advantage, the defect is that the viscosity is obviously affected by temperature. Mainly used for all kinds of box sealing, box sealing, paper packaging, beverage bottle labels, sealing aluminum foil, flexible packaging and other packaging; environmentally friendly paper pallets, etc., suitable for various materials. Carton sealing glue is used for bonding various varnishing, polishing, calendering, PP compounding and other PET, PP transparent boxes, films and non-woven products, cosmetic box packaging, food box packaging, cigarette box packaging, Tetra Pak packaging, etc. , assembling furniture edge sealing, electronic industry, automotive interior sealing, vehicle lamp manufacturing, windshield assembly, etc.), non-woven sanitary napkins, diapers, diapers, insoles, disposable daily necessities, coated composite trademark paper, labels Double-sided tape, sticky mouse board, sticky fly paper, wooden floor, carpet glued, Band-Aid, medical breathable tape, color box packaging, carton packaging glue, adhesive tape and other difficult-to-stick materials have strong adhesion ; Good thermal stability, no impurities, good operability; excellent weather resistance; aluminum foil sealing hot melt adhesive has unique water resistance and waterproof characteristics. Hot-melt pressure-sensitive adhesive is a kind of plastic adhesive. Its physical state changes with the change of temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.
