BYK® -333

Technical Datasheet | Supplied by BYK
BYK® -333 by BYK is polyether-modified polydimethylsiloxane. Acts as a silicone based surfactant and a wetting agent.
  • It is recommended for solvent-borne, solvent-free and aqueous systems.
  • Its separation or turbidity may occur at temperatures below 5°C.
  • Through a series of tests, however, it should be ascertained as to whether foam is being stabilized by this additive before large-scale application starts. The adhesion and cratering should also be evaluated.
  • BYK® -333 has excellent compatibility. It strongly reduces the surface tension of adhesive systems and increases surface slip.
  • It also increases anti-blocking properties and considerably improves substrate wetting.
  • It can be used universally in all systems and well suited for adhesives in comparison to silicone oils.
  • Its recommended level based upon total formulation is 0.05 - 0.3% in aqueous and UV systems up to 1.
