- Applications
Main applications for the PAT-ADD SU 4S series generally involve water/oil or water/solid interfaces, where interfacial tension equalization or modification is necessary. Application are in inks, paints, heat sensitive adhesives, fountain solutions, compounded materials for leather, emulsion polymerization, pigment grinding aids, cleaners, agricultural chemicals, shampoo, metalworking fluids, adhesive, paper coatings, pigment dispersions, colorants, latex dipping, drilling needs, coatings and other similar processes.
- Application in Coatings and Inks:PAT-ADD SU 4S (notably SU 4E, H and PA solutions) is widely used as a multipurpose problem solver. The strong effect of lowering dynamic surface tension indicates that PAT-ADD SU 4S exhibits exceptional wetting properties, as in the case of rapidly created new interfaces, exemplified by coil, air or airless spray, turbo bell, printing and other high speed application processes. Additionally, it offers defoaming properties. PAT-ADD SU 4S is also used for water-borne industrial paint to minimize foam formation and enhance flow and leveling. Another application is in aqueous wood coatings, where foam, leveling or adhesion issues are all addressed. Moreover, as an alternative to classic surfactants, water resistance is superior.
- PAT-ADD SU 4S (notably SU 4E, H, PA) is highly recommended for all printing methods with aqueous ink formulations; low dynamic surface tension.
- Various applications: PAT-ADD SU 4S shows excellent wetting of hot melt pressure sensitive adhesives applied on plastics. Leather chemicals: water borne leather chemicals must exhibit good wetting properties, especially dynamic wetting. PAT-ADD SU 4S is successfully used for this; leather finishes, shoe polishes etc
