Application Information

Coatings Industry
Special Features and Benefits

BYK-A 530 is a highly effective defoamer and air release additive for solvent-borne and solvent-free coating systems. It is effective during manufacture and processing and is particularly recommended for epoxy resin systems.

Recommended Levels
0.2-0.8% 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
To achieve optimal defoaming, the defoamer should be added already to the millbase. If incorporating at a later stage, sufficiently high shear forces must be applied to ensure a good distribution and to prevent cratering.

 

Ambient-curing Plastic Systems
Special Features and Benefits

BYK-A 530 is a highly effective air release additive, which reduces the formation of foam during the manufacture and processing of epoxy resin systems to obtain blister-free surfaces.
Recommended Levels
0.5-2% 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
Stir into the resin before adding other components. It is also possible to add the additive to finished systems.

 

Pultrusion of Plastic Systems
Special Features and Benefits

Prevention of air entrapment during manufacture and application (pultrusion). Particularly recommended
for plastic systems which are based on epoxy resins.
Recommended Levels
0.5-2% additive (as supplied) based upon the resin and curing agent.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
Stir into the resin before adding other components.

 

Adhesives & Sealants
Special Features and Benefits

BYK-A 530 is a highly effective air release additive, which reduces the formation of foam during the manufacture and processing of adhesives and sealants. Particularly recommended for epoxy resin-based systems.
Recommended Levels
0.5-2% 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
Stir into the resin before adding other components.
