Principles for selecting defoamers for water-based varnish
Compatibility: Ensure complete compatibility between defoamers and water-based varnish systems, without affecting the storage stability and performance of the coating.
Efficiency: It can quickly and effectively eliminate foam, and has lasting foam suppression ability.
Environmental friendliness: Complies with environmental regulations, is non-toxic and harmless, and does not pollute the environment.
Economy: Choose a cost-effective defoamer while ensuring performance.

Matching method
Laboratory testing: Evaluate the performance of different defoamers in specific water-based varnish systems through small-scale experiments.
Production verification: Conduct trial production on the production line to observe the actual application effect of defoamers, including defoaming speed, defoaming persistence, and their impact on coating performance.
User feedback: Collect and analyze user feedback, continuously optimize the matching scheme of defoamers.
