BYK® -320

Technical Datasheet | Supplied by Byk (Altana Group)
BYK® -320 by Byk (Altana Group) is a solution of a polyether-modified polydimethylsiloxane. Acts as silicone-containing surface and defoaming agent. Exhibits high temperature stability and levelling properties. Possesses defoaming properties that intensifies with increasing polarity. Provides strong reduction of surface tension. It thereby improves the wetting of critical substrates. Suitable for non-polar to medium-polar systems. Recommended for all ambient curing resin systems such as unsaturated polyester resins and epoxy resins. IT conforms to the compositional requirements of the German BfR-Recommendation XIV ‘Plastic Dispersions’ and XXXVI ‘Paper and board in contact with food’ (due to cross reference). Typical level of BYK® -320 ranges from 0.05-0.6% (as supplied) based on the total formulation. It is listed in TSCA, EINECS, DSL, ENCS, IECSC, AICS, NZIoC and PICCS. Complies with REACH (1907/2006), RoHS (2002/95/EC), WEEE (2002/96/EC), CONEG and RoHS 2 (2011/65/EC).
