Properties of Water-borne Binders used for Automotive Coatings

Acrylic core-shell polymers have been used as principal pxjlymers for aqueous metallic basecoat paints [37—40]. The anionic shell allows pseudoplastic flow behavior which ensures parallel orientation of the aluminium pigments in the wet paint film. This orientation and the low solids content are responsible for the metallic gloss and high color flop (change in color observed on varying the viewing angle) of the basecoats. [Pg.176]

To improve the water resistance, branched vinyl esters with long hydrophobic chains can be used [49]. [Pg.177]

Emulsion polymerization is carried out as a semi-continuous batch process [50]. [Pg.177]
