Abstract
The present invention relates to a pre-paint composite comprising an aqueous slurry of TiO2 particles and attached and unattached polymeric binder, and a sufficient amount of a secondary alcohol ethoxylate of the formula C10-15H22-32O(CH2CH2O)xH to give 35 to 90 weight percent attachment of polymeric binder to the TiO2 particles, based on the weight of total polymeric binder in the pre-paint composite, where x is from 15 to 50; and the O(CH2CH2O)xH group is bonded to a CH group on the C10-15H22-32 chain. The present invention also relates to a coatings composition containing the composite as well as a process for preparing the pre-paint composite and the coatings composition.
