1. Application fields of vinyl resin
By industry, the global vinyl resin market is largely classified into three categories: composites, paints, coatings, and others. Vinyl resin matrix composites are widely used in pipelines, storage tanks, construction, transportation and other industries.
Vinyl resin’s excellent corrosion resistance and excellent physical and chemical properties make it the material of choice for a large number of chemical anti-corrosion FRP projects. Such as glass fiber reinforced plastic tanks, pipes, towers and corrosion-resistant grilles, etc.; anti-corrosion projects, such as high corrosion-resistant floors, high-strength FRP products; heavy-duty anti-corrosion glass flake coatings, flake cement; power plant desulfurization and anti-corrosion, high temperature resistance, strong acid resistance Strong alkali; chemical workshop workbench acid and alkali resistance, high temperature corrosion resistance, etc.
In recent years, with the innovation and development of the special functionalization of vinyl ester resin, it has obtained some new applications in many downstream fields:
1) Vinyl ester resin glass flake cement has been well promoted and applied in the field of flue gas desulfurization in non-thermal power plants, especially in the field of pool tank lining in the chemical industry.
2) High-build vinyl ester resin coatings, including flake coatings and non-flake coatings, have been widely promoted and applied; 300μm film thickness vinyl ester resin coatings have begun to market and show a rapid growth trend;
3) Vinyl ester resin with high oxygen index and low smoke density has been popularized and applied in the field of FRP with both corrosion resistance and flame retardant;

4) Vinyl ester resin with zero shrinkage and high toughness has been widely promoted and applied in FRP helmets, fishing rods and other fields;
5) Vinyl ester resin with high strength and high elongation has been widely promoted and applied in the field of FRP structural parts with special requirements;
6) Special functionalized vinyl ester resin with ultra-high temperature resistance (above 200℃ in gas phase) and ultra-low temperature resistance (-40℃) has been popularized and applied;
7) Vinyl ester resin has been popularized and applied in the field of special electrical materials (such as insulating FRP for locomotives, semiconductor carbon rods, etc.);

2. Application field of epoxy resin
The excellent physical, mechanical and electrical insulation properties of epoxy resin, its bonding properties with various materials, and the flexibility of its use process are not found in other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and is widely used in various fields of the national economy.

①Paint
The application of epoxy resin in coatings accounts for a large proportion, and it can be made into varieties with different characteristics and uses. Its common features: 1) Excellent chemical resistance, especially alkali resistance; 2) Strong adhesion of paint film, especially to metals; 3) Good heat resistance and electrical insulation; 4) Paint film color retention Sex is better.
Epoxy resin coatings are mainly used as anticorrosion paints, metal primers, and insulating paints, but coatings made of heterocyclic and alicyclic epoxy resins can be used outdoors.
②Adhesive
Epoxy adhesives are an important variety of structural adhesives. In addition to poor adhesion to non-polar plastics such as polyolefins, epoxy resin is also suitable for various metal materials such as aluminum, steel, iron, copper; non-metallic materials such as glass, wood, concrete, etc.; and thermosetting plastics such as phenolic , amino, unsaturated polyester, etc. have excellent adhesion properties, so it is called the universal glue.
③ Electronic and electrical materials
Due to its high insulation performance, high structural strength and good sealing performance and many other unique advantages, epoxy resin has been widely used in the insulation and packaging of high and low voltage electrical appliances, motors and electronic components, and has developed rapidly.
Mainly used for: 1) pouring of electrical and motor insulation packages; 2) potting insulation of devices with electronic components and circuits. 3) Electronic grade epoxy molding compound is used for plastic sealing of semiconductor components; 4) In addition, epoxy laminated plastics, epoxy insulating coatings, insulating adhesives, and electrical adhesives are also widely used.
④Engineering plastics and composite materials
Epoxy engineering plastics mainly include epoxy molding compounds and epoxy laminates for high pressure molding, as well as epoxy foams. Epoxy engineering plastics can also be regarded as a generalized epoxy composite material. Epoxy composite material is an important structural material and functional material in chemical industry, aviation, aerospace, military and other high-tech fields.
⑤Civil construction materials
In the field of construction, epoxy resin is mainly used as anti-corrosion floor, epoxy mortar and concrete products, advanced road surface and airport runway, quick repair material, grouting material for strengthening foundation foundation, construction adhesive and coating, etc.
