BYK 1797 Defoamer

BYK-1797 is a wetting and dispersing agent designed for solvent-based systems and pigment concentrates. It functions by deflocculating pigments through steric hindrance, thereby enhancing key properties such as gloss, color strength, and flowability. This makes it a valuable additive for optimizing pigment-based formulations across various applications.

Features Of BYK 1797 Defoamer

  1. Formulated for Specific Systems: Tailored to perform effectively in solvent-based systems and pigment concentrates, ensuring strong compatibility with these formulations.

  2. Steric Hindrance Mechanism: Utilizes steric hindrance to break down pigment flocculates, preventing agglomeration and promoting uniform dispersion of pigments.

  3. Enhances Critical Properties: Improves gloss for a more polished finish, boosts color strength for vibrant and consistent hues, and enhances flowability for smoother processing and application.

Typical Applications Of BYK 1797 Defoamer

  1. Industrial Coatings: Enhances pigment dispersion in industrial coatings, improving gloss and color consistency for durable, high-quality finishes.

  2. Automotive Refinishes & OEM Automotive Coatings: Optimizes pigment performance in automotive coatings, ensuring high gloss, uniform color strength, and smooth application.

  3. Coil Coatings: Improves flowability and pigment dispersion in coil coatings, contributing to even, flawless finishes on metal coils.
