Application Information

Coatings Industry

Special Features and Benefits

BYK-1724 is recommended for defoaming aqueous coatings based on pure acrylate, acrylate/polyurethane and polyurethane in the pigment volume concentration range (PVC) 0-25. The additive is effective when used in all standard application methods such as rolling, painting, spraying, and pouring.

Recommended Levels

0.1-0.5% additive (as supplied) based on the total formulation – in exceptional cases up to 1%.

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 generally be added at any time during production. The defoamer should preferably be added to the let-down or be post-added.

 

Printing Inks and Overprint Varnishes

Special Features and Benefits

BYK-1724 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 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 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-1724 is recommended for defoaming aqueous dispersion adhesives.

Recommended Levels

0.05-1% 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 can be added at any time during production.

 

Household, Industrial, and Commercial Cleaning Agents

Special Features and Benefits

BYK-1724 is an Ecolabel-compliant silicone-containing defoamer for aqueous care products and cleaning agents, which can demonstrate its considerable defoaming effect already during production. This effect is maintained after the application.

Recommended Levels

0.1-0.5% 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 is preferably added at the start of formulation, however it is possible to use it at any stage of manufacture.
