Manufacturers offer acid resistant concrete concrete manufacturer plain clay

With an acidic resin, a carboxyl group, the epoxy ring opening, and then with a polyurethane adhesive in the isocyanate-reactive. You can also epoxy resin dissolved in ethyl acetate, phosphoric acid heated reaction, the adduct added to the polyurethane adhesive; the beginning of sticky glue; thermal and hydrolytic stability, etc. can also be used to improve the 0 r reaction of an alcohol amine or amine polyol, the presence of tertiary nitrogen atoms in the adduct, may accelerate the NCO reaction. Epoxy resin excellent mechanical and electrical insulation properties, and adhesive properties of various materials, as well as its flexibility in the use of technology in other thermosetting plastics do not have. So it made coatings, composites, casting materials, adhesives, molding materials and injection molding material, it is widely used in various fields of national economy. Epoxy resins in coatings applications account for a large proportion, it can be made with different features, use different varieties. In common: 1. Excellent chemical resistance, particularly alkali resistance. 2. Paint adhesion, particularly for metals. 3. It has good heat resistance and electrical insulation. 4. Paint color retention is good. But bisphenol A type epoxy poor weather, easy to powder paint outdoors due to loss of light and plump, not suitable for outdoor paints and decorative coatings of high use. Therefore mainly used for anti-corrosion epoxy paint, metallic paint, insulating paint, but paint heterocyclic and alicyclic epoxy resin can be used outdoors.
