Classification by use
1. Sealing adhesive

Mainly used for the connection of doors, windows and prefabricated houses. The high-end sealing adhesives are silicone and polyurethane adhesives, and the mid-range ones are neoprene adhesives, polyacrylic acid, etc.

2. Adhesives for building structures

Mainly used for the connection between structural units. Such as external repair of reinforced concrete structures, metal reinforcement and fixation, and construction on site, epoxy resin series adhesives are generally considered.

3. Adhesives for automobiles

It is divided into 4 types, namely, adhesives for car body, interior decoration, windshield and car body chassis.

4. Adhesives for packaging

It is mainly used to make pressure-sensitive tapes and pressure-sensitive labels, and to bond the surface of packaging materials such as paper, plastic, and metal. The adhesive for paper packaging materials is polyvinyl acetate emulsion. Adhesives for plastic and metal packaging materials are polyacrylic emulsions, VAE emulsions, polyurethane adhesives and cyanoacrylate adhesives.

5. Electronic adhesives

The consumption is relatively small, currently less than 10,000 tons per year, most of which are used in integrated circuits and electronic products, and now mainly use epoxy resin, unsaturated polyester resin, and silicone adhesive.

By Ingredient
There are many types of adhesives, the more common ones are: urea-formaldehyde resin adhesives, polyvinyl acetate adhesives, polyacrylic resin adhesives, polyacrylic resins, polyurethane adhesives, hot melt adhesives, epoxy resin adhesives, synthetic adhesives and so on.

1. Silicone adhesive

It is a kind of sealing adhesive, which has the characteristics of cold resistance, heat resistance, aging resistance, water resistance, moisture resistance, high expansion and contraction fatigue strength, small permanent deformation and non-toxicity.

2. Polyurethane adhesive

A variety of materials can be bonded, and the physical and chemical properties of the material can be maintained at low or ultra-low temperature after bonding. It is mainly used in shoemaking, packaging, automobiles, magnetic recording materials and other fields.

3. Polyacrylic resin

Mainly used in the production of pressure-sensitive adhesives, but also in the textile and construction fields. Construction adhesives: mainly used for construction decoration, sealing or bonding between structures.

4. Hot melt adhesive

According to different raw materials, it can be divided into EVA hot melt adhesive, polyamide hot melt adhesive, polyester hot melt adhesive, polyolefin hot melt adhesive, etc.

5, epoxy resin adhesive

It can bond between metals and most non-metallic materials, and is widely used in construction, automobiles, electronics, electrical appliances and daily household items

6. Urea-formaldehyde resin, phenolic, melamine-formaldehyde adhesive

Adhesives for wood processing: for medium density fiberboard, gypsum board, plywood and particleboard, etc.

7. Synthetic adhesive

Mainly used in wood processing, construction, decoration, automobile, shoemaking, packaging, textile, electronics, printing and binding and other fields.
