Air Products supplies a line of high performance dispersants that are suitable for the dispersion of pigments and particles in aqueous systems. The products have been designed to provide outstanding performance in wetting, milling, stabilization and application performance and are classified into two categories: disperants for resin-free systems and dispersants for resin-containing systems. The first category includes electrosteric stabilizing dispersants designed to be the primary stabilizer in resin-free dispersions. Providing the complete stabilization necessary for optimal performance, these products offer a range of options for various pigment particle and application demands. The second category includes products designed to work in conjunction with other stabilizing polymers such as grind resins or other polymeric dispersions. These products are largely nonionic dispersants designed to provide performance improvement in resin-containing systems.
