how to use
- How to use
- 1. Mix according to designated mixture ratio and apply evenly.
2. Preheat the basis material at 80 - 120 ℃ for 10 - 30 minutes to eliminate cutting oil and debris.
3. Maintain the surface temperature of the basis material at 40 - 50 ℃.
4. Impregnate in well-mixed varnish for 2 - 5 minutes. (Vacuumed impregnation can increase infiltration rate)
5. Leave until the varnish doesn’t fall of the basis material (10 - 30 minutes at room temperature)
6. Dry according to designated hardening conditions. - Remarks
- 1. Liquid B (Hardener) is sensitive heat so store refrigerated.
2. When the varnish temperature is high, there is risk of varnish turning into gel so please maintain
the varnish temperature inside the tank below 30 ℃.
3. Instructions above may vary depending on type of basis material and line conditions.
