Afcona -5054

High molecular weight carboxylic acid salts. Acts as a wetting and dispersing additive to prevent sedimentation as well as flooding of pigments. Helps to prevent interfacial tension between the hydrophilic pigments/extenders and the binder, forming a lattice structure with the pigments at the same time. It stabilized pigment through electrical charge repulsion forces. Compared to AFCONA-5044, AFCONA-5054 has more polar groups and a higher molecular weight. Due to these facts AFCONA-5054 gives better anti-settling and antiflooding properties than AFCONA-5044. Is ideal for dispersing organophilic Bentonites, because it reduces dispersion time, improves the storage stability of the final paste and gives a thixotropic, easily processed paste-product. Can cause discoloration in nitrocellulose varnishes and cause gel in certain UPE resin. Used in primers, decorative paints, marine and heavy duty paints. Addition and dosage: 0.2 - 2.0% based on inorganic pigments, 30.0 - 50.0% based on Bentonites.
