The epoxy resin coating is used as a latent crosslinking agent.Ambush crosslinking agent is mixed with epoxy resin, relative long-term stability at room temperature (epoxy resin general requirements in more than 3 months, just have large practical value, the ideal insist on half a year or more than one year), and only when it is exposed to heat, light, moisture and other conditions, the crosslinking reaction.
This kind of crosslinking agent is basically the physical and chemical method of sealing the crosslinking agent active.Therefore, in some books, these species are also classified as latent crosslinking agents, which may actually be called functional latent crosslinking agents.Because the latent type cross-linking agent can be mixed with epoxy resin made from a type liquid complexes, simplify the procedures of the application of epoxy resin with, its application range from single to coating packaging adhesives, impregnating varnish, potting compound, powder coating, etc.
Latent type of crosslinking agent is becoming more and more attention in abroad, can be said to be the focus of the research and development, all kinds of crosslinking agent modified varieties and cooperate with the new technology emerge in endlessly, very active.
Is commonly used in corrosion protection engineering of epoxy resin in addition to the used alone, also can and unsaturated polyester resin, vinyl ester resin, phenolic resin and furan resin and other resin composite use, form a composite structure to give full play to their strengths, reduce cost, improve product quality and convenient construction.
It can also be modified with other resin to form modified resin, which has physical and chemical methods.Epoxy coal tar is a typical physical modification of epoxy resin, which is between epoxy and coal tar.Secondary resins in physical modified resin generally account for 30-50% of the total.After the chemical modification of resin, the properties of the products have already changed, and vinyl ester resin is the most typical epoxy resin.Sometimes with good comprehensive performance of two or more than two kinds of resin material, according to their respective characteristics in the different parts of the project unified different tectonic locations of construction can generate a single material is difficult to achieve significant results.
Experts from epoxy resin application field, points out the development direction of crosslinking agent, crosslinking agent can adapt to the special environment Such as in a damp, underwater, outdoor and other harsh environments to keep good performance stability of crosslinking agent.Electrical performance, mechanical properties and excellent mechanical properties will be greatly developed.Electron beam and light crosslinked products are becoming more and more important.

The epoxy coating is developed in the direction of crosslinking agent
The user made higher and newer requirements for crosslinking, such as:
Use absolute safety and reliability to adapt to global trends in environmental protection, health and safety;
The effect of the application is significantly enhanced and the quality outstanding;
Convenience of use and storage;
The price, the quality ratio is appropriate, the cost - the efficiency balance, is desirable to buy and use;
High purity and transparency.
The development of the series, specialization, rationalization and elaboration.
In compliance with environmental regulations and meet the needs of users, it is a long-term task for the manufacturer to reduce costs and achieve higher profits.
