Ciba Launches Two New High-Performance Dispersants for Coatings

Published on 2008-09-08. Author : SpecialChem

BASEL, Switzerland -- Ciba has introduced two new dispersants for industrial and automotive coatings. Ciba® EFKA® 4310 and Ciba® EFKA® 4320 are designed to improve the stability of pigment dispersions and their compatibility with resins, thereby increasing flexibility in manufacture and allowing substantial cost savings. They are produced by controlled free radical polymerization (CFRP), a novel additive technology.

"EFKA® 4310 and EFKA® 4320 extend Ciba's range of dispersants produced by CFRP, providing the benefits of controlled molecular structures to a wider range of applications," said Andreas Tuerk, Global Head of Ciba's Business Line Paints & Coatings.

EFKA® 4310 and EFKA® 4320 perform excellently with a broad range of organic pigments and carbon black. EFKA® 4310 is tailor-made for coil coat systems, and is also suitable for use with a wide variety of resins. EFKA® 4320 is designed for thermoplastic acrylic systems and it, too, is compatible with numerous different resin types.

CFRP offers new tools for optimizing polymer architecture, for example of pigment dispersants. Specific tailoring of both pigment affinity and resin compatibility increases the stability of pigment dispersions and their compatibility in individual resin systems, enhancing the quality of coatings as well as increasing flexibility in manufacture. It also allows substantial cost savings, because a single pigment dispersion is suitable for numerous resin types.
