Solsperse® Dispersant

Titania nanoparticles were first surface-modified with polybutylene succinimide diethyl triamine (OLOA370) [87-91] and then 5wt% of the hydrophobized material was dispersed in styrene prior to a miniemulsification process. About 89% of the titania could be encapsulated in 73% of the PS, but pure polystyrene particles were still detected. Another efficient compatibilizer for titania is Solsperse 32000, a polyamine/polyester. By modifying titania with this polymer, hybrid nanoparticles with PS and PS-co-polybutylacrylate(PS-co-PBA) could be generated [92-95].

Solsperse 2400 (Zeneca) is a polymeric dispersant. Levelling and wetting additives improve the film appearance. Bentonite is added to prevent settling of the pigment. Fluorad FC-430 reduces cratering but can have a negative effect on recoatability.

SOLSPERSE 3000, a hyperdispersant originally developed for the dispersion of titanium dioxide in airdrying paints [5], was identified as showing benefit in the processing of rigid Polyvinylchloride compound. In the case of the Polyethylene masterbatch study, a novel hyperdispersant, SOLPLUS DP310 was developed. This hyperdispersant optimizes both the polymer chain chemistry and the molecular weight to achieve effective dispersion.
