The chlorinated rubber (CR) system was prepared
according to a proprietary formulation (Entreprise Nationale
Algérienne de Peinture, ENAP, Algeria) using chlorinated parafins
(32 wt.% of the CR binder) with 50 and 70% of chlorine content as
plasticizers and calcium carbonate and titanium dioxide as pigments.
CPs (0.5, 1.5 and 3 wt.%) were added to the CR system and
dispersed using a high speed, high-shearmixer (Dispermat VMAGeltzmann
GmBH D-51580 Reichshof, Germany) with 5-cm Cowles
blade at 7000 rpm for 20 min. The fineness of the grind was 7 on the
Hegman scale
