PURMOL™ 3ST Paste is made of Purmol molecular sieve and castor oil. It includes a synthetic 3A zeolite with a pore size of approximately 3 Angstroms (0.32 nm). This allows for selective adsorption of molecules based on molecular size and polarity. In practice, Purmol adsorbs water but not solvents, resins, or pigments.

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.

Dynasylan® VTEO is a bifunctional organosilane possessing a reactive vinyl group and a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactvity allows Dynasylan® VTEO to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as a crosslinking agent, adhesion promoter and/or surface modifier. Dynasylan® VTEO is a colorless, low­viscosity liquid with a typical aromatic odor.

PURMOL™ 3ST is a potassium (K) type A zeolite with a pore size of approximately 3 Angstroms (0.32 nm). Purmol 3ST 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.
