Styrene Sulfonate

In this experiment, NaSS showed the best performance in terms of mechanical stability, foaming and water absorption. This was attributed to the good polymerizability and surface activity of NaSS. But there is still room for improvement, especi…

Improved Plasticizers Help to Fill the Gap in Polysulfide Sealants

While plasticizers serve a critical function in polysulfide sealants, regulatory concerns have made many traditional plasticizers undesirable. Formulators have new options to maximize performance in polysulfides while also replacing chemistrie…
