Methyl Tetrahydrophthalic Anhydride MTHPA CAS 19438-64-3

Methyl Tetrahydrophthalic Anhydride (MTHPA) is a widely used anhydride curing agent for epoxy resins. With excellent thermal stability, electrical insulation, and mechanical properties, it is ideal for producing high-performance thermosetting materials. MTHPA is employed in electronics, coatings, adhesives, and composite materials.

– Colorless to slight yellow liquid

– It has high purity and light color and luster. It can be directly adjusted into all kinds of colorful epoxy resin products.
– It has low viscosity. It has the characteristics like: good casting, embedment and impregnation technology. It can improve the performance of curing material and the affinity of lamination and basic material.
– It has the characteristics like: stable performance, low freezing point and long using life. It can be stored for a long time at room temperature and easy for pipeline transportation. It is suitable for production automation and severe cold region.
– It has small volatility and low toxicity, only 1/20 – 1/40 toxicity of the amine curing agent. Its irritation to human eyes and skin is small.
-It has good dissolubility. This product can dissoluble with all epoxy resins. The mixing viscosity is low, meanwhile, has low pyrogenic effect and shrinkage during the heated curing process.
