The solvent of water-based varnish is mainly water, which has almost zero volatility and very good leveling properties. However, water as a water-based varnishing solvent also has shortcomings, such as slow drying speed, easy to cause process failures such as unstable product size, easy to cause foaming problems, reduce quality and shorten the service life of products.
To do this, we can choose to include the appropriate amountWater-based varnish defoamerto dynamically eliminate floating or suspended foam and avoid the accumulation of large amounts of foam. So, what are the overall advantages and development trends of water-based varnish defoamers?Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
First, the overall advantages of water-based varnish defoamer
1.Rapid defoaming:Water-based varnish defoamer has strong defoaming performance and long-lasting foam inhibition performance, which can quickly and well eliminate foam in water-based varnish and control the generation of foam throughout the production process.
2.Improves radiance:Water-based varnish defoamer can not only eliminate foam, but also improve the gloss of the coating film, make the printed matter more beautiful, enhance the adhesion of the coating film, and improve the quality and durability of the printed matter.
Second, the development trend of water-based varnish defoamer
1.High performance:In order to meet the needs of printed matter, water-based varnish defoamers will continue to develop in the direction of high performance, improve defoaming efficiency and foam inhibition performance, while maintaining good leveling and gloss.
2.Environmental protection:The environmental protection requirements will be more stringent, and the water-based varnish defoamer will pay more attention to environmental performance, using environmentally friendly raw materials and formulas to reduce the impact on the environment.
3.Specialization:According to the needs of different prints and production processes, water-based varnish defoamers will develop in the direction of specialization to provide customized solutions for different fields.
4.Diversity:In order to meet the needs of different customers, water-based varnish defoamers will develop in a diversified direction, including products with different models and different properties to meet the individual needs of different customers.
