How to discern the quality of varnish

Source:   Release time:2019-05-14   Click on the quantity:179

At the time of the printer, the varnish was determined after the printing pattern was completed. The quality of varnish determines whether the pattern can be brighter and brighter. Therefore, how do we determine the quality of varnish when we purchase varnish? After summarizing the data, we have obtained the following judgment methods.

1, smell the smell. The taste of a good varnish is very small, and its varnish oil content is about 95% or more. This varnish has a low volatility and the odor after curing is also very small.

2, the skin irritation. Take a small amount of varnish and place it on the back of the hand. Observe for 15 minutes or so. If the skin turns red or blisters, the quality of the varnish will not work. Can not be purchased for use.

3, leveling. We sprayed varnish on the finished prints. Observe whether there are ripples, ripples indicate poor leveling. We need to solve this problem by reducing the viscosity and extending the coating and curing time.

4, measured solvent content. Place the Varnish in a graduated vessel and place it for 10 h. Observe the scale to see how much is evaporated. Good varnish generally does not see a drop in surface position. If there is a drop in position, there is more solvent in the varnish, which is a product that the original varnish has been added with thinner.

It is recommended that when buying varnish, try to buy quality and high quality varnish. The use of quality and high quality varnish can make the printed product better, and it is best to use the varnish sold by the manufacturer. This is the most suitable varnish after many tests by the manufacturer.
