STEPAN® MWA-263 is a nonionic reverse eo/po block copolymer that exhibits fast-breaking, low foaming, and defoaming properties that can be used in lubricants in synthetic and semi-synthetic metalworking fluids. It can be used as a component of lubricants, gear and chain oils, metalworking fluids, hydraulic fluids, and plasticizers.

STEPAN® MWA-560 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that can exhibit hydrolysis resistance and good thermal stability. It can also exhibit a good hardness/flexibility balance, clarity, and low color. It can be used in metalworking formulations for improved lubrication properties. It shows improved lubrication by showing a reduced average scar when compared to the current industry standard.

STEPANATE® PTSA-C is a crystalline p-toluene sulfonic acid used as an intermediate in fine chemical manufacture, dye and pigment manufacture, metalworking, and catalyzing crosslinking reactions. Holding kosher certification makes it applicable in industrial products and institutional and industrial cleaning markets, particularly in cutting fluids and foundry catalysts.

STEPANATE® PTSA-C99 operates as a crystalline p-toluene sulfonic acid, fulfilling similar roles as an intermediate within fine chemical manufacture, dye and pigment manufacture, metalworking, and catalyzing crosslinking reactions. Like its counterpart, it holds kosher certification and serves industrial products and the institutional and industrial cleaning markets. Its application focuses on cutting fluids.

POLYSTEP® HPE serves as a functional monomer in both emulsion and solution polymerization systems. Its incorporation enhances substrate adhesion, provides corrosion resistance, improves pigment dispersion, and imparts antistatic properties to polymers. Key features of this base chemical include excellent adhesion and corrosion resistance.

STEPAN® MWA-570 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that exhibits hydrolysis resistance and good thermal stability. It exhibits a good hardness/flexibility balance, clarity, and low color. It is used in metalworking formulations for improved lubrication properties and is a great option as a chlorinated paraffin replacement, either alone or with the addition of phosphate esters. It also shows improved lubrication by showing a reduced average scar when compared to the current industry standard.
