BYK-1165 Defoamer

BYK-1165 is a specialized additive that functions as both a dispersing agent and a viscosity depressant, designed specifically for highly filled PVC plastisols. It significantly improves the wetting of pigments and fillers in PVC plastisol systems. By reducing the attractive forces between particles, it effectively prevents agglomeration, ensuring a more uniform distribution of solids. This leads to enhanced color development and more stable viscosity during storage. It is widely applied in various PVC-based products, contributing to better processing efficiency and improved product quality.

Features Of BYK-1165 Defoamer

  1. Viscosity Reduction for PVC Systems: Specifically designed to reduce viscosity in PVC formulations, facilitating easier processing, mixing, and application.

  2. Outstanding Wetting Properties: Ensures effective wetting of pigments, fillers, or substrates, promoting uniform dispersion and adhesion.

  3. Excellent Flow and Leveling: Enhances the flow and leveling characteristics of formulations, resulting in smooth, even surfaces with minimal defects.

Typical Applications Of BYK-1165 Defoamer

  1. Baking Paints: Used in baking paint applications to eliminate boiling defects and control foam, ensuring a high-quality, smooth finish after curing.

  2. Industrial Coatings: Ideal for a range of industrial coatings, enhancing their surface integrity, performance, and aesthetic appeal for consistent, reliable results across diverse applications.
