The blending ratio of UV varnish usually includes multiple components, and the specific ratio varies according to different needs and formulas.
For example, a common UV light oil formula includes the following ingredients and their proportions:
WUV 50: TMPTA 30: 4-chlorobenzophenone (BP) 2: RUNTECURE? 1056 1: Isopropanol 12: Water 5 1
In addition, there is a formula for waterproof mist UV varnish, with a volume ratio of UV varnish to matte oil between 12:1 and 50:1, and a more preferred ratio of 20:1 to 40:123.
The method of increasing brightness can be achieved by adding fluorescent whitening agent A-1. The specific operation is to add 0.02% fluorescent whitening agent during the production process, and 200 grams can be added to one ton of UV varnish. Another method of brightening is to add liquid brightener in a ratio of 1000:1 to the stirring tool, and stir thoroughly until transparent.
