Coatings Industry
Special Features and Benefits
SilibaseDF-3524 is particularly suitable for pigmented high gloss emulsion systems based on styrene acrylate, acrylate or acrylate/polyurethane with a pigment volume concentration of 18-25. The additive defoams
particularly high-gloss and satin-gloss systems, even in airless application.
Recommended Levels
0.1-0.8% 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.
Adhesives
Special Features and Benefits
SilibaseDF-3524 is recommended for defoaming aqueous acrylate-based adhesives.
Recommended Levels
0.05-0.5% 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.
