Troykyd D235 Defoamer

Troykyd D235 is a high-performance silicone-based defoaming and anti-foaming agent, specifically formulated for water-based coatings, inks, and other aqueous systems. It efficiently eliminates and prevents foam formation, with excellent compatibility across a wide range of formulations—ensuring minimal impact on surface appearance and coating properties.

Features Of Troykyd D235 Defoamer

  1. Effective Foam Control: Rapidly breaks down existing foam and provides long-lasting anti-foaming protection during manufacturing, processing, and application.

  2. Wide Compatibility: Works seamlessly with acrylic, styrene-acrylic, and other waterborne resin systems, making it suitable for diverse industrial applications.

  3. Low Surface Tension: Enhances flow and leveling while preventing defects such as cratering or pinholing.

  4. Thermal Stability: Maintains performance across a broad temperature range, ensuring reliability in high-temperature processes.

  5. Environmental Friendliness: Compliant with regulatory standards for low VOC emissions, aligning with sustainable manufacturing practices.

Typical Applications Of Troykyd D235 Defoamer

  1. Architectural Coatings: Ensures consistent foam control for high-quality, defect-free finishes.

  2. Industrial Paints: Prevents foam-related issues during production and application, maintaining coating integrity.

  3. Printing Inks: Controls foam in aqueous ink systems, improving print quality and process efficiency.

  4. Adhesives: Eliminates foam formation to enhance bonding performance and surface smoothness.
