Usage:

1. Can be used for polyester, epoxy resin, but the effect is not as good as tetrabromophenic anhydride. Tetrachlorophenic anhydride is also an intermediate in organic synthesis of pesticides (phthalein), dyes, drugs, plasticizers, fireproof paints, etc. It is used as a phthalocyanine green pigment and dye intermediate, and is also the raw material of alkyd resin. This product is used as flame retardant epoxy resin reactive accelerant and curing agent. This product is also the intermediate of organic synthesis of pesticides, dyes, drugs, plasticizers, fireproof paint and so on.

2. Tetrachlorophenic anhydride is widely used in flame retardants, pesticides, pigments, coatings and other industries, especially as a reactive flame retardant or flame retardant curing agent of unsaturated polyester and epoxy resin, which not only makes the resin have good flame retardancy and mechanical properties, but also has good high temperature resistance and light radiation stability. A series of inflammable plasticizers with excellent comprehensive properties can also be prepared.
