Strodex PSK-28 Potassium salt Mixture of potassium salt of phosphated coester of alcohol and aliphatic ethoxylate and potassium salt of phosphated aliphatic ethoxylate Dexter Chemical Dispersing agents >> Surfactants-like >> Phosphate esters Wetting agent/ Wet edge enhancer >> Surfactant Coatings >> Waterborne Neutralized Surfactants for Paint & Coatings STRODEX PSK-28 A 1-4 mixture of STRODEX PK-90 and STRODEX SEK-50D which combines the advantages of both products STRODEX PK-90 Very efficient dispersing/wetting agents Effective auxiliary for titanium dioxide and extender pigments Promotes color acceptance Improves gloss Extremely effective for iron oxide color pigments Eliminate or minimize hazing in gloss or semi-gloss paints Wet out difficult-to-wet surfaces Help prevent crawling, cratering and pinholeing Anti-rusting properties Help minimize nailhead and flash rusting Effective with polymeric paint thickeners May help reduce blocking With hexaline glycol added STRODEX SEK-50D Auxiliary pigment dispersant Promotes high color acceptance Neutralized surfactant. Used as a very efficient dispersing and wetting agent, as an effective auxiliary for titanium dioxide and extender pigments and as an auxiliary pigment dispersant. Improves gloss. Provides very good efficiency for iron oxide color pigments. Reduces hazing in gloss or semi-gloss paints, nailhead and flash rusting. Gives wet out of difficult-to-wet surfaces, prevention of crawling, cratering and pinholeing, efficiency with polymeric paint thickeners and reduction of blocking. Contains hexaline glycol. Promotes high color acceptance.
