WACKER® SG 3381 is a polyalkylene oxide-modified polydimethylsiloxane that contains organo-functional groups in the α,ω-position. This unique structure gives a functional value of 2 per modified polydimethylsiloxane. The functional groups are chemically bonded to the polydimethylsiloxane through chemically inert alkylene spacer groups, which are highly stable to hydrolysis.

Kemsurf CA-EH is a calcium salt of a biodegradable dodecylbenzene sulphonic acid. The base acid for Kemsurf CA-EH is manufactured by SO3 sulphonation to produce a product of good color and low inorganic content. Kemsurf CA-EH is a hydrophobic anionic surfactant and functions as an emulsifier for oils and aromatic solvents in the formulation of degreasers. It finds many applications, however, as an emulsifier for pesticide and herbicide systems, especially where spray application is involved. Kemsurf CA-EH may also be used in the emulsification of waxes and hydrocarbon solvents. This product has good compatibility with other anionics and nonionic surfactants and maintains good stability, detergency, foaming power and soil suspension in alkaline, mild acid, low electrolyte and hard or soft water.
