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 / ãŽ, 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.
