Water-based adhesive to non-toxic, non pollution favored, but the downside is slow drying, poor water resistance, frost is bad. Solid part should be increased to speed up the drying rate, using cross-linking method, increasing the drying speed and water resistance to extend its application.
Solvent-based adhesives without solvents means, because no solvent evaporation into the atmosphere, will not cause pollution and harm.
Most epoxy, anaerobic adhesive, a cyanoacrylate adhesive, aerobic modified acrylic adhesives, solvent free polyurethane adhesive, light curing adhesives are considered solvent-free varieties.
Solid-based adhesive is to use solid form, such as hot melt adhesive, hot melt pressure sensitive adhesive, water soluble powder glue, glue stick reactive, solid adhesive rod such office, in the coating and bonding process are non-volatile release, no environmental pollution.
Use of powdered rubber respected abroad, with stable performance, and no environment pollution. U.S. CP adhesive produced a urea formaldehyde resin powder, itself contains a curing agent and filler, odorless, no pollution, no poison, used as an excellent general-purpose wood adhesive. China has been the emergence of a new type of high-strength high-quality powder adhesive - strong state house powder (4), mixed with water into polymer dispersions, has outstanding adhesion, water resistance and resistance to aging. U.S. production - the kind of widely used epoxy glue gun, in the emergency repair, plugging very convenient.
Fast-drying solvent-based adhesives, water resistance is good, although a greater pollution and toxicity, but still can not completely replace the water-based adhesives, can use low toxic or nontoxic solvent such as cyclohexane, ethyl acetate, butanone, 1,1 a dichloroethane, dimethyl carbonate, etc., made of non-toxic or low toxic solvent-based adhesives, the domestic market, there have been no shoes, "toluene" polyurethane adhesives, shoe-free "BTX" then branch neoprene adhesive, no "toluene" SBS adhesive-type effects. It is worth mentioning dimethyl carbonate (DMC) is a new low-toxicity solvents fine. Japan has been prepared with the DMC solvent-based adhesives as the main solvent, has formed the scale of domestic production.
Clean production of new technology to achieve economic and environmental efficiency, the production environment-friendly adhesive.
Renounce the use of flavors of methyl methacrylate, use of high boiling point of monomer. Production of fast curing modified acrylate adhesive structure.
In the adhesive formulation and production process does not use toxic materials, such as formaldehyde, chlorinated solvents, aromatic solvents, fillers and other toxic heavy metals.
