BYK-MAX D 4221

BYK MAX D 4221 is a highly functionalized, polymer additive specially developed for dispersion and wetting of pigments and fillers prior to compounding processes. BYK MAX D 4221 efficiently wets and disperses solid additives like pigments, carbon blacks and fillers due to its low melting point and pigment affinic groups. This leads to steric stabilization and prevents reagglomeration of solid particles. BYK MAX D 4221 facilitates uniform dispersion of additives into polymer matrices. Its high compatibility and dispersion effectiveness helps achieve consistent and improved properties in end products. BYK MAX D 4221 is recommended for use in thermoplastics and aids in developing advanced materials with enhanced characteristics like mechanical, optical and electrical properties through homogeneous incorporation of performance enhancing additives.
