how to use
- How to use
- 1. Mix evenly after adding the substances according to the designated mixing ratio.
2. Defoam with vacuum to eliminate air pockets.
3. Inject well-mixed epoxy to the substrate.
4. Dry according to the designated curing conditions. - Remarks
- 1. Instructions above may vary depending on the type of substrate and the painting line conditions.
2. Liquid B is weak against moisture, so use the product quickly after opening it.
3. If the humidity is high, there is a possibility of exterior defect due to foaming during the curing.
So use the product in an indoor space where humidity can be controlled.
4. Please refer to the MSDS when handling the product.
