Feb 28, 2025
Product Name: Defoamer
Item No.: SilibaseDF-0019
Composition
Solution of a polyether-modified polydimethylsiloxane.
Description
Chinese Factory of Analogue BYK-019 Defoamer with Long-term and shear stability. SilibaseDF-0019 is silicone-containing defoamer for aqueous systems, printing inks, overprint varnishes and dispersion adhesives. Compatible defoamer. Prevents foam during grinding. Long-term and shear stability. Particularly suitable for resin-free grinds (slurries).
Key Features and Benefits
China Analogue BYK-019 Defoamer suitable for defoaming of water-based pigment concentrates.
SilibaseDF-0019 is mainly used in water-based systems, there is a good defoaming and antifoaming effect in production and construction; Good compatibility, small impact on color and gloss, not easy to produce shrinkage holes; This defoamer proves excellent long-term storage stability; It is also suitable for defoaming of water-based pigment concentrates.
Typical Physical Properties:
Appearance: transparent liquid
Active content: approx.100%
Applications
Printing Inks and Overprint Varnishes
Special Features and Benefits
SilibaseDF-0019 is particularly suitable for aqueous overprint varnishes based on acrylate dispersions, polyurethane dispersions and polyurethane/acrylate combinations and for defoaming pigment concentrates. To reduce microfoam, a combination of SilibaseDF-0019 with BYK-019 in a ratio of 3:2 has proven successful in defoaming pigment concentrates.
Recommended Use
The additive is particularly recommended for aqueous systems and UV systems.
Recommended Levels
0.1-1% additive (as supplied) based upon total formulation.
The above recommended levels can be used for orientation. Optimal levels are determined
through a series of laboratory tests.
Incorporation and Processing Instructions
Due to its high incompatibility, the defoamer must be incorporated at high shear forces to ensure a good distribution. Otherwise defects may occur in the system.
