Applications:

It is one of the best solidifier or curing agent for epoxy resins, It is a new material for electronic and mechanical products. It is widely used in casting, sealing and covering of electronic devices, such as output transformer, capacitor and inter sensor.

Features:
1. High purity and light luster: Can be used to prepare colorful epoxy resin solidifier.
2. Low viscosity: It is easy to be casted and sealed, while casting, plenty of fillers are acceptable, thus can improve the quality of finished product.
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 is just 2.5% of amine solidifier in toxicity. Low loss on drying.

Storage: Store in cool, dry and ventilated place, keep away from direct sunlight.
Packing: 220kg iron drum, 17.6mts per 20ft container
