Chemical Composition

BYK-A 530 Defoaming Polymer and Polysiloxane Solution

BYK-A 5300.81 5.0 >95
Solvent: Hydrocarbon Mixture (Paraffinic, Naphthenic)
The data provided on this datasheet are typical values and not product specifications.
Recommended Usage
% Additive Usage (as supplied) based on total formulation: In exceptional cases up to BYK-A 530  (0.2 - 0.8)

Addition Method and Processing Guidance
For optimal performance, the defoamer should be added to the grinding material before grinding.
If added at a later stage, sufficiently high shear forces must be applied to ensure good dispersion of the defoamer and prevent cratering.
The full effect of the defoamer is achieved 24 hours after incorporation into the system.
