Coatings Industry
Special Features and Benefi ts
The additive provides a slight reduction of the surface tension of coating systems and is a leveling additive with defoaming properties, particularly for non-polar to medium polar systems. Its defoaming effect intensifi es with increasing polarity. BYK-320 prevents problems with ghosting and telegraphing. To prevent these defects, the additive must be used in the coating layer that is to be recoated.
Recommended Use
The additive is particularly recommended for solvent-borne coatings; however, it can also be used in aqueous systems.
Recommended Levels
0.05-0.6 % 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 incorporated during any stage of the production process, including post-addition.
Special Note
Unlike so-called silicone oils, this additive is very user friendly. Nevertheless, before use it should be determined in a series of tests whether foam is stabilized in certain systems. Similarly, the recoatability and cratering should be checked.
Ambient-curing Plastic Systems
Special Features and Benefi ts
The additive provides a slight reduction of the surface tension and is a leveling additive with defoaming properties, particularly for non-polar to medium-polar systems. Its defoaming effect intensifi es with increasing polarity.
Recommended Use
The additive is recommended for all ambient curing resin systems such as unsaturated polyester resins and epoxy resins.
Recommended Levels
0.05-0.6 % 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 incorporated during any stage of the production process, including post-addition.
