1、 Diverse forms.
A variety of resins, curing agents, modifiers system can adapt to almost all kinds of applications on the requirements of the form, epdm seal strip can range from very low viscosity to high melting point solids.
2, curing convenience.
Selection of a variety of different curing agents, epoxy resin system can be cured almost in the temperature range of 0 ~ 180 ℃.
3、 Strong adhesion.
The existence of polar hydroxyl groups and ether bonds inherent in the epoxy resin molecular chain makes it have high adhesion to various substances. Epoxy resin curing shrinkage is low, resulting in low internal stress, which also helps to improve the adhesion strength.
4、 Low shrinkage.
Epoxy resin and the reaction of the curing agent used is carried out by direct addition reaction or ring-opening polymerization of the epoxy group in the resin molecule, there is no water or other volatile by-products released. They and unsaturated polyester resin, phenolic resin, compared to the curing process shows a very low shrinkage (less than 2%).
5、 Mechanical properties.
The cured epoxy resin system has excellent mechanical properties.
6、 Electrical properties.
The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance.
7、 Chemical stability.
Usually, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy system, chemical stability also depends on the resin and curing agent selected. Appropriate choice of epoxy resin and curing agent can make it have special chemical stability performance.
8、 Dimensional stability.
The above-mentioned many properties of the synthesis, so that the epoxy resin system has outstanding dimensional stability and durability.
9、 Resistant to mold and mildew.
The cured epoxy resin system is resistant to most molds and can be used under harsh tropical conditions.
