Feature

High mechanical properties. Epoxy resin has strong cohesion and dense molecular structure, so its mechanical properties are superior to general thermosetting resins such as phenolic resin and unsaturated polyester

The coating of plastic-coated fire pipes is made of epoxy resin, which has strong adhesion. The epoxy resin curing system contains extremely active epoxy groups, hydroxyl groups, and polar groups such as ether bonds, amine bonds, and ester bonds, which provide the epoxy cured product with polarity properties such as metal, ceramics, glass, concrete, and wood. group. Material with excellent adhesion

Curing shrinkage is small. Generally it is 1%~2%. It is one of the varieties with the lowest curing shrinkage among thermosetting resins (phenolic resin is 8% to 10%; unsaturated polyester resin is 4% to 6%; silicone resin is 4% to 8%). The linear expansion coefficient is also very small, generally 6×10-5/℃. Therefore, the volume does not change much after curing
