Water based varnish, as an environmentally friendly surface decoration material widely used in the modern printing industry, not only endows printed materials with bright luster and weather resistance, but also significantly reduces the emission of VOCs (volatile organic compounds). However, in the production and application process of water-based varnish, the foam problem often puzzles producers and processors. Therefore, water-based light oil defoamers have emerged as a key additive to solve this problem.

Water based varnish defoamer is a chemical additive specially used to eliminate or inhibit foam in water based varnish system. It can destroy the foam structure in a very short time, making the liquid return to a calm state, thus ensuring the normal processing and application effect of water-based varnish.

In printing, coating and other processes, the foam in water-based varnish will not only affect the appearance quality of products, such as fish eye, pinhole and other defects, but also reduce production efficiency, increase energy consumption and cost. Therefore, the use of efficient and environmentally friendly water-based light oil defoamers is of great significance for improving product quality, saving resources, and protecting the environment.
