3. Application:
- To be used together with liquid epoxy resin, suitable for epoxy embedding material, casting material, coating material, floor material, and adhesive. Textile treating agent, silk shrinkproof and resistance agent, Perchloride and PVC heat - stabilization agent.
- Dosage: In general, 669 should be 10-30% of Epoxy Resin in weight. 669 contains epoxy group which can neutralize curing agent, so it is necessary to add the quantity of curing agent in course of using.
4. Packing
- Packed in 20 kg/barrel or 200 kg/barrel, or 1000kgs/IBC container
