Name: Troy Troysol 307 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Troy Troysol 307 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based industrial formulations, including high-solids and low-VOC systems.
Low addition rate—typically effective at 0.05–0.3% w/w—minimizing formulation impact and cost-in-use.
Thermally stable up to 120°C, supporting use in elevated-temperature processing conditions.
Non-staining and non-silicone-residue-forming in most cured or dried films, ensuring surface integrity.

Typical Applications Of Troy Troysol 307 Defoamer

Architectural and industrial waterborne coatings (e.g., acrylic and PVA emulsion paints).
Adhesives and sealants, particularly latex-based and pressure-sensitive formulations.
Printing inks—including flexographic and gravure inks—for improved runnability and mist control.
Construction chemicals such as cementitious mortars, tile adhesives, and self-leveling underlayments.
Textile auxiliaries, especially in dyeing, printing, and finishing baths where foam interferes with uniform application.
