Crosslinking agent for epoxy coatings industry
From the traditional view, the upper and lower end of the industrial chain associated with epoxy resin is a master slave relationship, with the upper end fixed and the lower end based on the application of the upper end product. But from the view of the modern development view, the upper end is also in constant innovation. The basis of innovation is the downstream application market demand. The coating industry is the most important application area in terms of epoxy resin crosslinking agent.
Development of coatings: 1. Low-carbon green products; 2. Functional products; 3. Special products.
Therefore, the development of epoxy resin crosslinking agent should also be towards low-carbon environmental protection materials; Functional materials development.
The development of coating industry has become the weathervane of epoxy resin and crosslinking agent industry. Because epoxy coatings excellent adhesion, resistance to chemical corrosion, thermal stability and colour retention, and many other features, is widely used in automobile, Bridges, ships, especially in steel structure, reinforced concrete shear larger dynamic load or coating.
Epoxy resin itself is not cross-linked at room temperature, so it has no practical value. However, epoxy resin containing active epoxy group in the molecular structure (CH - CH2 -), people take advantage of these active group, with different crosslinking agent of crosslinking reaction, then makes an epoxy resin into insoluble, not fuse with three dimensional network structure of all kinds of high polymer performance characteristics.
In this way, the application of epoxy resin suddenly open space, it is because of its excellent adhesion and sealing ability of corrosive medium, for half a century, are widely used in the corrosion resistance of paint coating of industrial products.
The epoxy resin needs to be formulated with any type of crosslinking agent, and it should be selected according to the performance requirements of the coating design, with the addition of the facial filler and various auxiliaries to obtain the coating for the application. Therefore, the development direction of epoxy resin, crosslinking agent industry, more attention should be paid to the development of coatings industry trends, epoxy crosslinking agent formula for research and development, should be to paint the demand of the market as a guide for design ideas.
The development trend of coating industry. The development and application of green coatings and functional coatings is one of the biggest topics in the industry.

In the industry, the public opinion about green paint has been "deeply popular", as the upper end chain of coating raw materials, should also cooperate with the paint industry to look at the green indicators, the characteristic products tilt.
Paint industry has/is qualitative change of the structure of products, powder coating, solvent-free coatings, water-based coatings, light crosslinking coatings, etc., it is these changes will promote epoxy resin, crosslinking agent and related the innovative development of the pigments, fillers, additives and new function.
Decorate in commonly used paint
1. Clear oil: mainly used for primer before painting.
2. Original paint: also known as lead oil, it is a mixture of pigment and dry oil, which is used to adjust putty.
3. Mixed paint: also known as mixed paint, grease paint and natural resin paint.
4. Varnish: also known as fan water, oil - based varnish and resin varnish. The varieties have ester gum varnish, phenolic varnish, alkyd varnish, nitro - clear
5. Lacquer and shellac varnish, etc. Good gloss, quick film, wide use.
6. Enamel: made of varnish and paint, commonly used in two types of phenolic enamel and alkyd enamel.
7. Anti-rust paint: oily anti-rust paint and resin anti-rust paint.
8. Latex paint: lacquer film has certain air permeability and alkali resistance. After drying, the paint film is not blistered, discolored, non-sticky and used for interior wall finishing. It is non - toxic to human body and pollution-free.
