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.
