Tetrachlorophthalic anhydride C8CL4O3

1. Can be used for polyester, epoxy resin, but the effect is not as good as tetrabromophthalic anhydride. Tetrachlorophenic anhydride is also an intermediate in organic synthesis of pesticides (phthalide), dyes, drugs, plasticizers, fireproof paint and so on. Used as phthalocyanine green pigment and dye intermediate, 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 pesticides, dyes, drugs, plasticizers, fireproof paint and other organic synthesis intermediates.

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