Methyltetrahydrophthalic Anhydride( MTHPA )
CAS No.11070-44-3 HS Code: 29172090 UN No.: N/ A EC NO: 247-830-1
Molecular Structure:

Molecular Formula: C9H10O3
Molecular Weight: 116.17
MSDS: Available on request
FP: 140
Property:
Clear yellow liquid, no impurity.Soluble in benzene, acetone, etc. Sensative in moisture.
1.High purity and light luster: Can be used to prepare colorful epoxy resin solidifier;
2.Low viscosity: It’ s easy to be casted and sealed, while casting, plenty of fillers are acceptable, thus can improve the quality of the finished products.
3.Good stability: The duration is longer and the freezing point is much lower.It can be stored at room temperature for long time.
4.Low volatility: Low toxic. It’ s just 2.5% of amine solidifier in toxicity.Low loss on drying.
