The difference between protective film adhesive coating, water glue, oil glue and pressure sensitive adhesive:
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-soluble, with its functionality, environmental protection, and low price, will be the direction of future coatings. The disadvantages are poor film formation, poor washing fastness, and PU cannot be pasted with hot air glue.
2. Oil-based coating adhesive: Oil-based coating adhesive is made by dissolving acrylic or polyurethane with oily 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 a commonly used coating glue at present. 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 Wholesale Window Glass Laminated Film 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, Kai Film Technology has higher and higher environmental protection requirements for coating adhesives.
3. Hot-melt pressure-sensitive adhesive Hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, which is mainly composed of synthetic rubber, resin and rubber oil, etc.
A new type of adhesive tape coated on tissue paper, cloth or plastic film and other substrates. 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 Wholesale Self adhesive Wall Paper 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.
