Wood Coating Foaming Issues? Chemi Tech's Defoamer Has the Answer

Bubble formation in wood coating applications often frustrates finishing technicians. Whether spraying or brushing, surface bubbles not only affect appearance but may also compromise protective properties and shorten the wood product's lifespan.

A furniture manufacturer producing high-end solid wood pieces encountered persistent micro-bubbles in their coating film, especially during humid seasons. After adjusting spray parameters, changing thinners, and even modifying drying processes with limited success, they found the solution in Chemi Tech's KM-220 defoamer series.

Chemi Tech engineers identified that the coating formula tended to generate microfoam in humid conditions, where conventional defoamers failed to maintain long-term effectiveness. The KM-220 series stands out by:

Within two weeks of use, the manufacturer achieved a 35% reduction in coating defects. "Now we can confidently accept premium orders," commented their production manager.
