                                Hydrogels     Factice    Hot melts

Differences:

Hydrogels is made from water as a solvent to emulsify acrylic or polyurethane resin through specialized emulsifying equipment.Its biggest

advantages are: many varieties, environmental protection, low price, there are now many coatings are water soluble glue, such as:general

water-soluble PA, water-soluble PU and leather film glue, oil sense, shaving slurry and other functional slurry. Water solubility, with its

functionality, environmental protection, and low price, will be the future direction of coating. The disadvantages are poor film-forming, poor

water washing, PU can not be attached to hot air gel.

Factice is oily solvents (toluene, DMF, butyl ketones, etc.) as solvents to dissolve acrylic or polyurethane. Its advantages are goodfilm-forming,

good fastness, PU can paste hot air glue, is the current common use of coating glue. The disadvantage is due to the use of Factice, so the lack

of environmental protection, especially now oil prices, resulting in oil-based solvent prices all the way up, most of the coating glue because the

cost is too high, so the use of relatively poor oil-based solvents, resulting in environmental protection standards, in addition, with the further

improvement of environmental standards in various countries, Therefore, the environmental requirements of coating glue are getting higher and

higher.

Hot-melt pressure-sensitive glue is a kind of pressure-sensitive glue, mainly by synthetic rubber and resin and rubber oil mixed heating into

melting state and then coated on cotton paper, cloth or plastic film and other substrates and made of a new adhesive belt, low cost is its greatest

 advantage, the defect is that the viscosity is affected by temperature more obvious. Mainly used in all kinds of sealing boxes, sealing boxes, paper

 packaging, beverage bottle labels, sealed aluminum foil, flexible packaging and other packaging; Sealing glue for all types of polishing, 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, electronic industry, automotive interior sealing, car lamp manufacturing,

windshield assembly, etc.), non-woven sanitary napkins, diapers, Diapers, insoles, disposable life supplies, coating composite trademark paper,

label double-sided tape, sticky mouse board, sticky fly paper, wood flooring, carpet over glue, creative paste, medical breathable tape, color box

packaging, carton packaging glue, back adhesive adhesive buckle belt and other hard-to-stick materials have strong adhesive force; Aluminum foil

seal hot melt is uniquely water-resistant, waterproof characteristics. Hot-melt pressure-sensitive glue is a plastic adhesive, in a certain temperature

range its physical state changes with temperature, and chemical properties remain unchanged, its non-toxic tasteless, is an environmentally friendly

chemical products.


Identification Methods

The glue used in the glue is dissolved in water, the adhesive is soluble in oil, when distinguishing time can use water to wipe the adhesive surface,

can smoothly wipe off is the glue, the opposite is the oil glue, and hot melt glue is the best distinction, in the case of non-heating, its adhesive

surface is not adhesive hand, only when heated to the specified temperature, only when heated to the specified temperature, only has a stickiness.
