Application Information

Printing Inks and Overprint Varnishes
Special Features and Benefits

BYK-024 is recommended for defoaming aqueous printing inks and overprint varnishes based on acrylate/polyurethane and polyurethane. Also for aqueous 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
The additive can be added at any time during production. The amount of defoamer used is often divided (by adding 2/3 into the millbase and 1/3 into the let-down or finished product).

 

Coatings Industry
Special Features and Benefits

BYK-024 is recommended for defoaming high gloss emulsion systems based on acrylate/polyurethane and polyurethane in the pigment volume concentration range 0-25. The additive is effective when used in all standard application methods such as rolling, brushing, spraying and pouring.

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
The additive can be added at any time during production. The amount of defoamer used is often divided (by adding 2/3 into the millbase and 1/3 into the let-down or finished product).

 

Adhesives
Special Features and Benefits

BYK-024 is recommended for defoaming aqueous emulsion adhesives.
Recommended Levels
0.05-1% 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
The additive can be added at any time during production.

 

Glass fiber sizings
Special Features and Benefits

BYK-024 is recommended for defoaming when applying aqueous glass fiber sizings.
Recommended Levels
0.1-0.3% additive (as supplied) based on the 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
The additive may be added at any time during production while stirring.
