BYK® -354

Technical Datasheet | Supplied by Byk (Altana Group)
BYK® -354 by Byk (Altana Group) is a solution of a polyether-modified polydimethylsiloxane. Acts as anti-cratering and levelling surface agent. Exhibits thermal stability and helps in reducing surface tension slightly. It increases gloss and also has a de-aerating effect as a result of its high molecular weight & non-polar structure. It is completely miscible in water and incompatible with strong oxidizing agents. This product 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® -354 ranges from 0.1-1.5% (as supplied) based on the total formulation. Recommended for all ambient curing resin systems such as unsaturated polyester resins and epoxy resins. It is listed in TSCA, EINECS, DSL, ENCS, IECSC, AICS, NZIoC, ECSI and PICCS. Complies with REACH (1907/2006), RoHS (2002/95/EC), WEEE (2002/96/EC), CONEG and RoHS 2 (2011/65/EC).
