How to distinguish oil glue water glue hot melt glue
Double-sided adhesive tape is a film-based tape with adhesive on both sides. Common substrates are PI film, PET film, PE foam, etc. Common adhesives are silicone, acrylic, rubber, etc.
Double-sided adhesive tapes can be divided into oil, water, and hot-melt pressure-sensitive adhesives, depending on the adhesive system.

Water Glue

Water-based adhesives are produced by emulsifying acrylic or polyurethane resins with water as a solvent, using special emulsification equipment.
Its biggest advantages are variety, environmental protection, and low price, now there are many coatings are used water-soluble adhesive, for example, general water-soluble PA, water-soluble PU and leather film adhesive, oil sense wax sense, scratch color paste, and other functional pastes.
Water soluble is the future direction of coating with its functionality, environmental friendliness, and low price.
The disadvantages are poor film-forming, poor washing fastness, PU can not be attached to the hot air glue, and not being suitable for laminating sponge, foam, and other foam products.
 

Oil Glue

Double-sided adhesive oil glue is an oily solvent (toluene, DMF, butanone, etc.) as a solvent, the acrylic or polyurethane is dissolved and made.
Its advantages are good film formation, and good fastness, PU can stick to hot air glue, which is the current common use of coating glue.
The disadvantage is that due to the use of oil-based solvents, so the lack of environmental protection, especially now the price of oil, resulting in the price of oil-based solvents all the way up, most of the coating adhesive due to the high cost, so the use of poor oil-based solvents, resulting in environmental protection is not up to standard, addition, with the further improvement of national environmental standards, so the environmental requirements of the coating adhesive are increasingly high.
 

Hot-melt pressure-sensitive glue

Hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, mainly made of synthetic rubber and resin and rubber oil mixed into a melting state and then coated on cotton paper, cloth or plastic film, and other substrates and made of a new type of adhesive tape, low cost is its biggest advantage, the defect is that the adhesion is affected by the temperature is more obvious.
It is mainly used for sealing boxes, boxes, paper packaging, beverage bottle labels, sealing aluminum foil, flexible packaging, and other packaging; environmental protection paper pallet, etc. It is suitable for all kinds of materials.
Box sealing adhesive for all kinds of varnishing, polishing, calendering, PP composite, etc. PET, PP transparent boxes, film, non-woven products bonding, cosmetic box packaging, food box packaging, cigarette box packaging, Tetra Pak beverage packaging, etc., assembly furniture sealing, electronics industry, automotive interior sealing, lamp manufacturing, windscreen assembly, etc.), diapers, diapers, shoe inserts, disposable household goods, coated composite trademark paper, labels Double-sided adhesive tape, sticky mouse board, sticky fly paper, wooden flooring, carpet over glue, band-aids, medical breathable tape, color box packaging, carton packaging adhesive, backing adhesive tape and other difficult to stick materials are a strong adhesive force; good thermal stability, no impurities, good operability; excellent weather resistance; aluminum foil sealing hot melt adhesive unique water resistance, waterproof characteristics.
