Evaluation of the effect of temperature on the stability of metal soaps of dicarboxylic acids
Journal of Applied Sciences and Environmental Management, 2005 The thermal stability of calcium and zinc dicarboxylates was studied. The kinetics of the decomposition was studied thermogravimetrically at various temperatures. The rates of the first stage decomposition were used to assess the effect of temperature on

Manganese and Iron Catalysts in Alkyd Paints and Coatings
Inorganics, 2016 Many paint, ink and coating formulations contain alkyd-based resins which cure via autoxidation mechanisms. Whilst cobalt-soaps have been used for many decades, there is a continuing and accelerating desire by paint companies to develop alternatives for ...
