Abstract
Compositions comprising a liquid and fumed silica may be applied to fabric and other textile materials as a sealant, e.g., to protect against damage or deterioration. The composition may comprise liquid droplets at least partially or completely surrounded by fumed silica. The liquid may comprise water and one or more polymers, such as a fluorocopolymer and a functionalized anionic polymer.
Claims20
A particulate composition comprising:
- a liquid comprising water and about 5% to about 30% by weight of a polymer component comprising a first polymer and a second polymer different from the first polymer, the first polymer being chosen from an anionic polymer, an anionic copolymer, a fluoropolymer, a fluorocopolymer, an acrylic polymer, or an acrylic copolymer;
- and
- fumed silica at least partially surrounding droplets of the liquid.
A particulate composition comprising:
- a liquid comprising:
- water;
- a first polymer, and
- about 3% to about 10% by weight of a second polymer chosen from an anionic polymer, an anionic copolymer, a fluoropolymer, a fluorocopolymer, an acrylic polymer, or an acrylic copolymer;
- and
- about 1% to about 30% by weight hydrophobic fumed silica;
- wherein the fumed silica at least partially surrounds droplets of the liquid;
- and
- wherein the composition is in the form of a dry powder.

A particulate composition comprising:
- a liquid comprising:
- water;
- perfluoroalkyl acrylate;
- and
- an anionic polymer or an anionic copolymer;
- and
- about 5% to about 13% by weight hydrophobic fumed silica at least partially surrounding droplets of the liquid;
- wherein the composition is in the form of a powder, the composition being formulated to impart moisture resistance or stain resistance, or both moisture resistance and stain resistance, to upholstery when applied.
