Methyltetrahydrophthalic Anhydride

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.
