2. Application
721 curing agents can be used in low or zero VOC formulations. It can be used for a long time, dry quickly, and maintain good emulsion stability even when the solid content is low. After curing, the coating has high gloss, good performance of hardness and flexibility, and excellent adhesion to the concrete surface.
3. Storage and packaging
Stored in a cool and dry place with ventilation and can be sealed for 12 months.
Package:200kg/ iron drum.
