Study of Latex Migration Mechanism during Coating Consolidation
A new mechanism for latex migration during coating consolidation was proposed, which suggested that Brownian motion induced particle diffusion, as described by the classic Stokes-Einistein Equation for dilute suspensions, was the main force driving latex particles to migrate to the coating surface. Series of latex clay coating colors were prepared and apllied on impervious substrate. By measuring carbon content at coating surface dried under different conditions, the new mechanism was validated.
