- Application
A series of unique nonionic surface active agents, which provide both wetting and defoaming in the same product.Remark: Available in Ethylene glycol, 2-Propanol, Propylene glycol, Bytyl Carbitol and 2-Methoxymethylethoxypropanol solvents.
Main applications of the PAT-ADD SU 4 series generally involve water/oil or water/solid interfaces, where interfacial tension reduction is required. Application examples 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 the like.
Application in Coatings and Inks
PAT-ADD SU 4 (notibly SU 4 E, H and P solutions) is widely used as a multipurpose problem solver. The strong effect on lowering dynamic surface tension indicates PAT-ADD SU 4 showing favorable wetting properties, also in case of fast created new interfaces, such as in case of roller coating, as well as spray coating, brush coating, etc. Additionally it offers defoaming properties. PAT-ADD SU 4 is also used for water-based industrial paint to decrease foam formation; furthermore it enhances flow and leveling. An other application is in water-based wood coatings, where it solves foam, leveling or adhesion problems. Moreover it serves as an alternative to classical surfactants, in case water resistance if the coating needing further improvement. Printing ink PAT-ADD SU 4 (notably SU 4 P, E, PA) is successfully used in flexo ink and offset printing. It speeds up ink penetration into the substrate such as paper and wetting onto PET. Furthermore, it acts as a defoamer.
In pen inks PAT-ADD SU 4 (for instance SU 4 P) is used as a dispersing agent and viscosity stabilizer. The excellent dynamic wetting ability helps to keep the writing smooth. Furthermore, it is used for its defoaming properties. The main application is as an interfacial tension reducer in high-speed printing processes. Using PAT-ADD S 4 typically improves the printing quality, thanks to the high dynamic surface tension reduction characteristics. Additionally, it is used in fountain solutions: PAT-ADD SU 4 reduces the risk of emulsifying and foaming of fountain solution.
Various applications: PAT-ADD SU 4 shows excellent wetting properties in hot melt pressure sensitive adhesives for instance if applied on plastic. Leather chemicals: as water based leather chemicals require good wetting properties, especially dynamic wetting. PAT-ADD SU 4 is successfully used in this application, inlcuding in leather finishes, shoe polishes etc.
- Dosage & Addition
The optimal amount of PAT-ADD SU 4 to be used is system and application related, but is typically in the range between 0.1% - 2% active matter by weight of the total formula. The optimum concentration to be used depends on the individual requirements and conditions and is advised to be determined experimentally.
