E-Sperse® 4754 is a new natural oil based dispersant that is effective in dispersing both inorganic and organic pigments into a variety of solvent and resin based coating formulations. Its multiple functionalities are effective anchoring groups for a wide variety of pigments. E-Sperse® 4754 has been shown to be especially effective for difficult to disperse solar reflective metal oxide pigments in urethane aircraft paint formulations. It is used as the sole dispersant in these formulations where a combination of conventional dispersants is usually required. Panels of urethane topcoats formulated with eight different pigments showed excellent weatherability at 3000 hours of xenon arc accelerated weathering. E-Sperse® 4754 also contains hydroxyl functionality which allows the dispersant to crosslink into urethane and melamine based formulations.
