Anionic Surfactants
Secondary alkyl sulfonates (secondary alkane sulfonates)
The Hostapur ® SAS series can be used as an emulsifier in the poly -
merization of E-PVC as well as in the production of styrene/butadiene
and of acrylonitrile/butadiene rubber. The Hostapur ® SAS range is also
Olefin sulfonates
Hostapur ® OS liquid is used as emulsifier in emulsion polymerization
of styrene/butadiene latex, styrene/butadiene rubber and acrylate and
styrene/acrylate dispersions. It also serves as air entraining agent in
concrete, especially for road pavements, mortar and plasters to im -
prove the resistance against ice pressure during freezing. Hostapur ®
OS liquid is particularly stable against calcium ions and, compared
to other air entraining agents such as sodium alkyl sulfates, Hostapur ®
Alkyl sulfates
Emulsogen ® EPA 1954 is used as an emulsifier for emulsion polymerization,
allowing the production of polymer dispersions with controlled
particle size and low coagulation during the polymerization process.

a suitable emulsifier in the polymerization of vinyl acetate and comonomers,
in the polymerization of acrylates and styrene/acrylates and
in the polymerization of styrene/butadiene latex.

OS liquid is more efficient and requires lower dosages. The powder
form Hostapur ® OSB is also used as air entraining and wetting agent
for mortars and plasters based on cement, gypsum or lime. Rapidly
soluble and highly efficient, it leads to a faster wetting of the solid
particles, enables fast air-entrainment and develops mirco foam at
a controllable air content of 20 - 35% in a short period of time.
Further more, it improves the plasticity and workability of plasters.
