Cyclic siloxanes in silicone-based surface additives
Purified alternatives to additives with a higher cyclic siloxanes content
BYK silicone additives with a cyclic siloxanes content
of 0.1 % or higher and their low cyclic alternatives:

What does “purified” mean?

As of June 2018, silicone-based products containing 0.1 %or more D4, D5, or D6 cyclic siloxanes must be labeled as
SVHC (Substance of Very High Concern) on the EU Safety
Data Sheet.

By adding an additional production step after manufacturing,the D4, D5, and D6 cyclic siloxanes content is reduced toless than 0.1 % each.

BYK offers purified alternatives with a residual D4, D5, andD6 content of less than 0.1 % each to ensure safe use inany formulation.
