AgeSin® DP-A2976 and AgeSin® DP-L1907 P are high molecular weight polymeric dispersants designed as cost‑effective, drop‑in alternatives to BYK‑9076. Both products deliver outstanding pigment wetting, efficient deflocculation, and long‑term dispersion stability across a wide range of solvent‑borne, solvent‑free, and ambient‑cure systems.
While they share the same core technology platform – high molecular weight copolymers with pigment‑affinic groups – each product is optimized for slightly different formulation priorities. This allows you to choose the best match for your specific resin system, pigment type, and processing requirements. Both are particularly well‑suited for PVC plastisol applications, providing excellent pigment dispersion stability and viscosity control.
AgeSin® DP-A2976 is a solvent‑free wetting and dispersing additive based on an alkylammonium salt of a high molecular weight copolymer. It is particularly effective for acidic and neutral carbon black pigments, as well as organic pigments in demanding industrial applications.
