    Abstract: An application method of enhancing the water repellence of a textile and/or enhancing a textiles ability to repel water soluble dirt, includes the steps of: a) applying an emulsified liquid composition on a textile, wherein said emulsified liquid composition includes only water, alkylalkoxysilane with said alkyl chain having a length of 10-30 carbons or carbon atoms higher than 12 but equal to or less than 18, at least one emulsifier, surfactant, thickener and/or stabilizer, a water soluble acid catalyst, and unavoidable impurities; b) optionally adding to the composition amino silicones for softness and durability enhancement of the water repellency; c) optionally adjusting the amount of the composition applied on textile; d) drying the treated textile until dry; e) curing the treated textile at a temperature of between 100-200° C.; and f) optionally removing the non-reacted composition residue from the treated textile by washing with water and optionally redrying the treated textile.

    Abstract: A flame-retardant composition has a plurality of particles with at least one porosity therein, a flame retardant gas occupying the porosity, and a matrix material in which said particles are dispersed. A sealant applied to at least a portion of the particles, wherein the sealant substantially prevents the gas from escaping the porosities. The matrix is a flame-retardant composition adapted to be applied to various surfaces. The matrix may also function as the sealant. The sealant is formed of a material that will break down and release the gas in the presence of water or flame or other selected conditions. The sealant may be a polymer material. This solves the problem of applying flame-retardant qualities to various surfaces.
