BYK 346

BYK 346 is a silicone surfactant for aqueous coatings, printing inks and overprint varnishes with strong reduction in surface tension resulting in significantly improved substrate wetting. It is a solution of BYK 345. The additive provides a large decrease in surface tension in aqueous systems and therefore improves substrate wetting and levelling in particular. Foam stabilisation does not occur - or only very minimally - and recoatability is not affected. The additive does not increase surface slip. If higher surface slip is desired, we recommend combining it with a polysiloxane such as BYK 333.
