In coating production, defoamers are essential additives to eliminate foam. However, incorrect usage may lead to adverse effects, compromising coating performance. Chemi Tech summarizes common issues and solutions below.
Excessive or unevenly dispersed defoamer can cause craters or fish eyes on the coating surface, affecting aesthetics and protection. Conduct trials to determine optimal dosage and ensure thorough mixing.
Poor compatibility between defoamer and the system may result in orange peel or haze. Chemi Tech's defoamers are designed to minimize such issues, but users should adjust dosage based on formulations.
Some defoamers may reduce coating gloss, causing dullness or unevenness. Selecting low-impact defoamer models and strict process control can mitigate this problem.
Overuse of defoamers may destabilize the coating system, leading to separation or sedimentation. Chemi Tech recommends lab tests to optimize formulations for synergy with other additives.
Chemi Tech offers high-performance defoamers for diverse coating systems. Precise dosage and proper dispersion can minimize side effects. For technical support, contact Chemi Tech for tailored solutions.
