The Difference Between Water Glue And Oil Glue
- Nov 16, 2018 -

The two most commonly used glues in the production of protective film can be divided into water-based glue and oil-based glue. The performance and price of the two glues are different. We have a detailed understanding of the following:

1. Waterborne coating adhesive is prepared by emulsifying acrylic acid or polyurethane resin with water as solvent through special emulsifying equipment. Its greatest advantage is: variety, environmental protection, low price, now many coatings are water-soluble sol, such as: general water-soluble PA, water-soluble PU and film adhesive, wax-sensitive oil, scratch size and other functional slurries. Water solubility will be the direction of coating in the future due to its functionality, environmental protection and low price. The disadvantage is poor film forming, poor washing fastness, and PU can not stick hot air glue.

2. oil coated adhesive:

Oily coating adhesive is made by dissolving acrylic acid or polyurethane in oily solvents (toluene, DMF, butanone, etc.). Its advantages are good film forming, good fastness, PU can stick hot air glue, is currently widely used coating glue. The disadvantage is due to the use of oily solvent, so a lack of environmental protection, especially now that oil prices lead to oily solvent prices sharply, most of the coating because the cost is too high, so the relatively poor oil solvent, leading to environmental standards, with the addition of further improve the environmental protection standards of all countries in the world Therefore, the environmental protection requirements for protective film coating adhesive are getting higher and higher.

3. another glue is also used more frequently: hot melt pressure sensitive adhesive.

Hot melt pressure sensitive adhesive is a kind of pressure sensitive adhesive. It is a new type of adhesive tape which is mainly made of synthetic rubber, resin and rubber oil mixed and heated to melt state and then coated on cotton paper, cloth or plastic film. Its greatest advantage is its low cost. The defect is that the viscosity is obviously affected by temperature. Mainly used for sealing boxes, sealing boxes, paper packaging, beverage bottle labels, sealing aluminum foil, flexible packaging and other packaging; environmental friendly paper stack board, etc., to adapt to all kinds of materials.

Sealing glue for all kinds of polishing, polishing, calendering, PP composite PET, PP transparent box, film, non-woven products, cosmetics box packaging, food box packaging, cigarette box packaging, Lile beverage packaging, assembly furniture edge sealing, electronic industry, automotive interior sealing, lamp manufacturing, windshield assembly, etc.), non-woven fabric health. Towels, diapers, diapers, insoles, disposable household goods, coated composite trademark paper, double-sided label tapes, sticky rat boards, fly paper, wood flooring, carpet glue, bandage, medical breathable tape, color box packaging, carton packaging glue, back adhesive buckle and other refractory materials have strong adhesion; thermal stability is good, No. Impurities, good operability, excellent weather resistance, aluminum foil sealing hot melt adhesive unique water and waterproof characteristics. Hot melt pressure sensitive adhesive is a kind of plastic adhesive. Its physical state changes with temperature in a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and it is an environmental friendly chemical product.
