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.
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
