Application of water-based varnish defoamer

in furniture manufacturing industry

Industry application: In the furniture manufacturing industry, water-based varnish is widely used due to its environmental friendliness, non toxicity, and easy drying characteristics. However, the water-based varnish is prone to produce foam during the coating process, resulting in uneven surface of the coating and affecting the beauty and quality. At this point, water-based varnish defoamers become particularly important. By adding an appropriate amount of defoamer to the water-based varnish, the production of foam can be significantly reduced, the smooth and uniform coating of the furniture surface can be ensured, and the overall quality of the furniture can be improved.

Features: The defoamer for water-based varnish is generally transparent lotion or semi transparent liquid, with good dispersibility and water soluble characteristics. Its pH value is usually between 6.5 and 7.8, which does not affect the basic properties of water-based varnish. At the same time, defoamer also has the advantages of low dosage, fast defoaming and long foam suppression time, which can quickly destroy the stability of foam and make foam burst quickly.

Advantages:

1. Improve the construction efficiency: the defoamer of water-based varnish can make the coating process more smooth and improve the construction efficiency by reducing foam interference.
2. Improve the coating effect: avoid coating defects caused by foam, such as bubbles, depressions, etc., and improve the flatness and aesthetics of the coating.
3. Environmental safety: Defoamers themselves are non-toxic and harmless, and will not cause harm to the environment and human health.
