Product Description

Product nameMethyltetrahydrophthalic anhydride (MTHPA)
CAS No.26590-20-5
Chemical Structure 

- 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.

Methyl tetra-Hydro Phthalic Anhydride (MTHPA) was used in the curing agents for epoxy resins, dry-type transformers, high voltage 
switches, mutual inductors, condensers, LED, etc. Relative to the general MTHPA, this specification have the following characteristics:

- Light color when curing ,suitable for white or colorless transparent products;
- Good heat resistance, higher Tg point.
- Faster curing speed , saving the amount of promoter;
- Larger viscosity, moisture absorption higher than the general MTHPA, shall be sealed.
