What is the difference between water based adhesive and Oily coating adhesive film?


Water-based coating glue is made by emulsifying acrylic or polyurethane resin through special emulsifying equipment with water as solvent.

The advantages of water glue are: many varieties, environmental protection, and affordable. At present, many coatings use water-soluble glue, such as: general water-soluble PA, water-soluble PU and film glue, oily wax, scratch Functional pastes such as color pastes. Because of its functionality and environmental protection, water-soluble glue does not require a solvent recovery device. In developing countries, water-soluble glue is often used for production. It is currently more commonly used in the coating industry.

The adhesive surface of the water-soluble adhesive-coated PE protective film should be avoided as much as possible, or reduce contact with water vapor, ultraviolet rays, and corrosive environments to avoid adhesive residue.

Water-based pressure-sensitive adhesives have suitable initial adhesion, peeling force, and holding power, and are suitable for the protection of various products. The protective film of water-soluble adhesives has good practical value. With fast drying speed and easy coating, it can meet the production requirements of various protective film manufacturers.

Oily coating adhesive is mainly a liquid made by copolymerizing acrylic monomers and imported auxiliary materials.

Oil-based pressure-sensitive adhesives also have good initial adhesion, peeling and holding power, transparency, and relatively stable adhesive properties.

The oil-based coating adhesive is made by dissolving acrylic acid or polyurethane with an oil-based solvent (toluene, DMF, methyl ethyl ketone, etc.) as a solvent. Its advantages are good film formation, fastness and high transparency. The disadvantage is that it uses an oily solvent, so it is lacking in environmental protection.

At present, HNHN have used water-based glue to produce protective films. Because it is more environmentally friendly. Our technology is very mature and can be used for most materials, such as relatively difficult-to-stick carpets, and stainless steel with high technical requirements.So we have the absolutely advantage in adhesive level.
