PURMOL™ 4ST is a sodium (Na) type A zeolite with a pore size of approximately 4 Angstroms (0.4 nm). PURMOL™ 4ST is recommended for use with high quality coatings. In general, we recommend the addition of 2.5% - 5% Purmol powder to the polyol component. This must be stirred thoroughly for a minimum of two hours to allow the Purmol to adsorb all the water before addition of the isocyanate. With metal dust coatings we recommend the addition of 0.5% - 2% PURMOL™ 4ST powder.
