Phthalic anhydride composition-tetrahydrophthalic anhydride
Tetrahydrophthalic anhydride is a widely used chemical raw material. It is used as a curing agent for epoxy resins, plasticizers for atomic ash resins, adhesives, paints, modifiers for unsaturated polyesters, agents for the fiber industry, and pesticides. Insecticide, humectant, polyester resin, etc. It is an acid anhydride curing agent with a cyclic structure. It has high heat resistance with epoxy resin cured products, good mechanical strength and electrical properties, but it is not prone to intramolecular movement and is brittle curing Agent. Tung oil has the best dryness, and the oil film has strong non-stick, strong adhesion, water resistance, alkali resistance, sunlight resistance and other properties. Methyl tungrate anhydride (MeMA) is an experiment of this kind of flexible anhydride curing agent obtained from tung oil through transesterification reaction and D-A addition reaction.
