Techniques for producing thixotropic paints etc. Part 2 Available to Purchase

Salts of aluminium and calcium such as stearates, octoates and naphthenates, are used to impart structure to oleoresinous paints. Alternatively, aluminium alcohoiates can be used as reactive intermediates which form salts by reaction with the medium. The use of these materials is generally restricted to flat or semi‐gloss paints and storage instability is sometimes encountered. A chlorinated rubber paint which contains titanium, kaolin, talc, a chloroparaffin plasticiser, and a solvent blend of hexyl acetate and xylene, is rendered thixotropic using a 1% level of aluminium stearate addition. The product is suitable for applying as thick corrosion‐resistant coatings to metals.
