The difference between the epoxy resin plate panels and eco

Epoxy resin is an organic macromolecule compound refers to molecules containing two or more than two epoxy groups, in addition to individual, their relative molecular mass is not high. The molecular structure of epoxy resin is the molecular chain containing epoxy groups and lively as its characteristic, the epoxy groups can be located at molecular chain end, intermediate or ring like structure. Because the molecular structure of epoxy containing active, so that they can be solidified with a variety of types of agent for crosslinking reaction and the formation of insoluble, infusible has three direction mesh structure of polymers.

Application characteristics

1, various forms of. A variety of resin, curing agent, modifying agent system can be adapted to almost all kinds of application form of the request, which can range from extremely low viscosity to high melting solid.

2, curing convenient. Choose a variety of different curing agent, epoxy resin system almost can be cured at 0 to 180 DEG C temperature range.

3, strong adhesion. The polar hydroxyl and ether bonds inherent epoxy resin molecular chain in existence, which has high adhesion to various substances. Shrinkage of cured epoxy resin is low, internal stress generated by small, it also helps to improve the adhesion strength.

4, low shrinkage. Epoxy resin and the curing agent for the reaction is by direct addition reaction or resin molecular central oxygen radical ring opening polymerization to, no water or other volatile by-products released. They and phenolic resin, unsaturated polyester resin, compared to a very low shrinkage sex shows during the curing process (less than 2%).

5, mechanical properties. Epoxy resin system cured with excellent mechanical properties.

6, electrical properties. Epoxy resin system cured is an excellent insulating material having a high dielectric property and high surface leakage resistance, arc.

7, chemical stability. Usually, the epoxy resin system cured with excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy system, chemical stability also depends on the selection of resin and curing agent. Proper selection of epoxy resin and curing agent, can make it has stable chemical properties of special.

8, dimensional stability. Integrated many properties mentioned above, the epoxy resin system with dimensional stability and durability outstanding.

9, mold resistance. Epoxy resin systems were resistant to most fungi, can be used in harsh tropical conditions.
