Abstract
The present invention provides a method and kit for the treatment of surfaces, such as the skin surface of a user, to impart hydrophobic characteristics upon the surface. The treatment of surfaces to impart hydrophobicity protects equipment, personnel, and animals from the effects of aqueous solutions such as water, toxic slurries, concrete, acids and bases.
Claims18
A kit for hydrophobic treatment comprising:
- a container;
- a first plurality of silica silylate particles of a first average size, wherein the first plurality of silica silylate particles comprises at least 10% of the volume of silica silylate particles in the kit;
- a second plurality of silica silylate particles of a second average size, wherein the second plurality of silica silylate particles comprises at least 10% of the volume of silica silylate particles in the kit;
- and
- a third plurality of silica silylate particles of a third average size, wherein the third plurality of silica silylate particles comprises at least 10% of the volume of silica silylate particles in the kit;
- wherein the first average size is greater than the second average size;
- wherein the second average size is greater than the third average size;
- wherein the silica silylate has been rendered hydrophobic by reaction with a hydrophobe;
- and
- wherein the silica silylate particles are contained within the container.
