It has high acid and alkali resistance, low water absorption, not easy to oxidize at normal temperature, and is not easily contaminated by medium. Besides hydrofluoric acid and hot phosphoric acid, it has excellent anti-corrosion effect on the acid of warm chlorine, hydrochloric acid, sulfuric acid, nitric acid and any concentration at normal temperature. The adhesive strength of the mixture is high and the heat resistance is good. Strong resistance to permeability, resistance to corrosion of organic solvents, acid and alkali resistant ideal binder, can be used in some occasions such as epoxy, phenolic and unsaturated polyester resins. It consists of two components, liquid and powder. When used, mix the two components in a certain proportion and use them.
