WACKER® SG 3381
WACKER® SG 3381 is a polyalkylene oxide-modified polydimethylsiloxane having organo-funtional groups in the α,ω-position. This results in a functionality of 2 per modified polydimethylsiloxanes. The functional groups are bonded to the polydimethylsiloxane by chemically inert alkylene spacer groups, which are stable to hydrolysis.
WACKER® SG 3381 is particularly suitable in numerous applications, including: coating to improve coefficient or friction and leveling properties. Due to WACKER® SG 3381 low surface tension it can yield high wetting, while also enhancing lubricity, sheen, gloss, anti-caking, static suppressing, antifoaming and moderate profoaming. It also demonstrates surfactancy properties that are of benefit in multiple other end applications. It is 100% concentrated, economical, and has low toxicity.
WACKER® SG 3381 has a shelf life of at least 18 months if stored in originally sealed containers at 25 ºC or 70 ºF. The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
