The difference among water-based, oil-based and hot melt pressure sensitive adhesive

Water-based pressure sensitive adhesive：

Water-based pressure sensitive adhesive is made by emulsifying acrylic or polyurethane resin with water as solvent through special emulsifying equipment. Its biggest advantage is variety, environmental protection, and low price, now there are a lot of coatings are water-soluble glue, such as general water-soluble PA, water-soluble PU and skin film glue, oil wax sense, scraping paste, and other functional paste.

Water solubility will be the direction of coating in the future because of its function, environmental protection, and low price. Disadvantages are poor film-forming, poor washing fastness, and PU can not stick to hot air glue.

Oil-based pressure sensitive adhesive：

Oil-based pressure sensitive adhesive is based on an oil-based solvent (toluene, DMF, butyl ketone, etc.) as a solvent, the acrylic or polyurethane dissolved. Its advantages are good film-forming, good fastness, PU can stick to hot air glue, and is currently widely used coating glue. The disadvantage is due to the use of oily solvents, so the environmental protection is a little short.

Hot melt pressure sensitive adhesive:

Hot melt pressure sensitive adhesive is a kind of pressure sensitive adhesive, which is mainly made of synthetic rubber, resin, and rubber oil mixed into a melting state and then coated on cotton paper, cloth or plastic film, and other substrates. Low cost is its biggest advantage, the defect is that the viscosity is affected by temperature is obvious.

Mainly used for sealing boxes, sealing boxes, paper packaging, beverage bottle labels, sealing aluminum foil, flexible packaging, and another packaging; Environmental protection paper pallet, suitable for all kinds of materials.

Sealing adhesive for all kinds of glazing, polishing, pressing, PP composite PET, PP transparent box, film, non-woven products bonding, cosmetic box packaging, food box packaging, cigarette box packaging, Tetra Pak beverage packaging, assembly furniture edge sealing, electronics industry, automotive interior seal, car light manufacturing, windshield assembly, etc.), non-woven sanitary napkins, diapers, diapers, in footings, Disposable daily necessities, coated composite trademark paper, double-sided label tape, sticky rat board, sticky fly paper, wood floor, carpet adhesive, Band-Aids, medical breathable tape, color box packaging, carton packaging adhesive, back adhesive buckles, and other difficult materials have strong adhesive force; Good thermal stability, no impurities, good operation; Excellent weather resistance; Aluminum foil sealing hot melt adhesive unique water resistance, waterproof characteristics.

Hot melt pressure sensitive adhesive is a kind of plastic adhesive, in a certain temperature range, its physical state changes with the temperature, and the chemical characteristics remain unchanged, its non-toxic and tasteless, and belongs to environmental protection chemical products.
