POLYSTEP TSP-16PE30 is a “bulky” emulsifier designed to deliver enhanced adhesion and improved water resistance. Its functionality is enabled through the reduced mobility of the surfactant due to its “bulky” nature. Learn More 


PSP buttonThe POLYSTEP® Solution Portal is a formulator’s tool to select the most appropriate Stepan chemistry.  Possible solutions can be searched by chemistry, by function, by application or by performance attribute.  Multiple APE-free and VOC-free options are available.


Línea de productos


Stepan leverages core technologies of sulfonation, alkoxylation (both ethylene and propylene oxides) and phosphorylation to offer a full line of surfactants for emulsion polymerization. POLYSTEP surfactants are used in systems consisting of acrylics (including styrene, vinyl and 100% acrylic), vinyl acetates, styrene butadiene and alkyds.  Stepan surfactants demonstrate efficiency, consistency and value-added performance benefits.
