Product Description
UVG-250 uv roller varnish is suitable for the whole-sheet roll coating of paper (applicable substrate: copper paper and white card paper, etc.). With good adhesion, flexibility, wear resistance and other characteristics, to provide good luster, wear resistance and other properties. This product is a base-free light oil, which can simplify the process and save the production cost.

Recommended Instructions of UV Roller varnish:
1. Stir or shake well before use to prevent stratification of light oil during placement.
2. The viscosity of UVG-250 uv roller varnish has been adjusted to the use viscosity. Generally, special diluent is not required.
3. When used, the coating thickness is recommended to be 10~12um, and the coating amount of 10g / ㎡ UV photofixation energy is set to 50~80mj / cm2The transfer speed is set to about 40M / min to ensure sufficient curing, otherwise the surface return adhesion and paint loss during the placement process will occur.
4. It is recommended to choose more than 2 medium and high pump lamps, line power 100W / ㎝, single lamp power 5k w / branch, lamp pipe is 12~15 ㎝ away from the substrate, lamp service life of 800 hours, replaced in time after aging, to ensure full curing.
