how to use
- How to use
- 1. Mix evenly after adding the substances according to the designated mixing ratio.
2. Preheat the substrate at 80 - 120 ℃ for 10 - 30 minutes to eliminate cutting oil and debris from the substrate.
3. Maintain the surface temperature of the substrate at 40 - 50 ℃.
4. Impregnate it in well-mixed varnish for 2 - 5 minutes. (Impregnation in the vacuumed state can increase the penetrance.)
5. Leave until the varnish does not fall off from the substrate (10 - 30 minutes at room temperature).
6. Dry according to the designated curing conditions. - Remarks
- 1. When the varnish temperature is high, there is a risk of varnish turning into gel. So maintain the varnish temperature inside the tank at below 30 ℃.
2. Instructions above may vary depending on the type of substrate and the painting line conditions.
