Abstract
Compositions comprising a liquid and fumed silica may be applied to surfaces as a sealant, e.g., to protect against damage or deterioration. The composition may be a powder, wherein a method of treating the surface includes applying pressure to the powder on the surface with an applicator, and the pressure releases the liquid sealant from the powder onto the surface. The liquid may comprise water and one or more polymers, such as a fluorocopolymer and a functionalized anionic polymer.
Claims20
A method of treating a surface, the method comprising:
- applying pressure to a powder on the surface with an applicator, wherein the powder comprises:
- a liquid sealant comprising water and at least two polymers chosen from anionic polymers, anionic copolymers, fluoropolymers, fluorocopolymers, acrylic polymers, and acrylic copolymers, and combinations thereof;
- and
- fumed silica;
- wherein the pressure releases the liquid sealant from the powder onto the surface.
A method of treating a surface, the method comprising:
- applying pressure to a dry powder on the surface by sweeping an applicator across the dry powder and the surface;
- wherein the dry powder comprises droplets of a liquid sealant at least partially surrounded by fumed silica, the liquid sealant comprising water, a first polymer, and a second polymer different from the first polymer, each of the first and second polymers being an anionic polymer, an anionic copolymer, a fluoropolymer, a fluorocopolymer, an acrylic polymer, or an acrylic copolymer;
- and
- wherein the pressure releases at least a portion of the liquid sealant from the fumed silica onto the surface.
A method of treating a surface inside a vehicle, the method comprising:
- applying pressure to a powder on the surface via an applicator, wherein the powder comprises droplets of a liquid sealant at least partially surrounded by fumed silica such that the powder is dry, the liquid sealant comprising:
- a first polymer chosen from an anionic polymer, an anionic copolymer, a fluoropolymer, a fluorocopolymer, an acrylic polymer, or an acrylic copolymer;
- a second polymer different from the first polymer;
- and
- from about 85% to about 98% water by weight, with respect to the total weight of the liquid sealant;
- wherein the pressure releases at least a portion of the liquid sealant from the fumed silica onto the surface.
