Silicone Defoamer ZG-6800

Defoamer ZG-6800: Technical Overview

Equivalent product：Elementis defom 6800

1. Application Fields

• Epoxy floor coatings: Ideal for industrial floors, garages, and commercial spaces to eliminate bubbles that cause pinholes or uneven surfaces.

• Screen printing inks: Effective in ink formulations for textile printing, packaging, and graphic arts, preventing foam during mixing and application.

• UV-curable inks: Suited for digital printing, label production, and decorative coatings, resisting foam during UV curing processes.

• Unsaturated polyester resins: Used in fiberglass composites (boats, automotive parts), artificial stone, and casting applications to prevent air entrapment.

• Other applications: Coatings for concrete, wood finishes, and high-viscosity adhesive systems.

Revised Application Scenarios (Common Expressions)

2. Usage Guidelines (Key Updates)

• For UV-curable inks: Ensure compatibility with photoinitiators; test curing speed and film hardness post-addition.

• In composite resins: Add during resin mixing phase to prevent bubbles in molded parts (e.g., fiberglass panels).

3. Key Operation Checklist (Application-Focused)

Application Type	Dosage Recommendation	Special Notes
Epoxy floor coatings	0.1–0.5%	Add before pigment dispersion for best results.
UV-curable screen inks	0.05–0.3%	Avoid overmixing to prevent air re-entrainment.
Unsaturated polyester resins	0.2–0.8%	Compatible with methyl ethyl ketone peroxide (MEKP) curing systems.

4. Industry Compliance Tips

• For printing inks: Confirm compliance with food packaging regulations (e.g., FDA 21 CFR 175.300) if used in contact applications.

• In composite manufacturing: Meets typical ASTM standards for resin defoaming agents (e.g., ASTM D2364 for viscosity control).
