In the formulation of water-based metallic paints, defoamer selection critically impacts coating appearance and application performance. Incompatible defoamers may cause craters, fisheyes, or uneven gloss, potentially compromising corrosion resistance. Chemi Tech, a leader in surface treatment, offers tailored defoaming solutions through advanced technology.
Defoamers work by reducing surface tension to destabilize foam. Metallic paints containing metal flakes and emulsifiers require silicone- or mineral oil-based defoamers with fast bubble-breaking speed and high compatibility.
- Customized Formulations: Designed for aluminum/zinc pigments to prevent substrate reactions.
- Low Foam Stabilization: Unique molecular structure minimizes post-application foam.
- Eco-Compliance: Meets VOC regulations and industrial coating standards.
- Testing Phase: Conduct dynamic stirring tests to evaluate defoaming efficiency.
- Dosage Control: Typical range is 0.1%-0.5%; excess may impair film wetting.
- Process Adaptation: Spray applications need foam-suppressing types, while roller coatings prioritize rapid bubble collapse.
Chemi Tech’s defoamers enhance leveling and metallic effects in water-based paints. For technical details, visit our official website for professional support.
