Relationships of formation and characteristics of colloidal particles in tin-containing organosols intended for activation of the surface of fibrous polyester materials

Resumo

Formation of colloidal particles in tin-containing alcoholic solutions was studied in relation to the SnCl₂ concentration, storage time, and kind of the solvent and stabilizing additive. The highest category of flame resistance and the highest resistance of the fireproofing coating to repeated launderings are reached when the poly(ethylene terephthalate) fabric is activated with alcoholic SnCl₂ solutions with high concentration of 10–15-nm colloidal particles prior to application of an inorganic fireproofing compound.
