Abstract
Physiologically acceptable and non-corrosive silicone compositions are used for treating surfaces such as glass, porcelain, ceramic, marble, granite, metal, coated metal, plastic, wood, painted wood, cement, leather, textile, cloth, and other hard or soft composite surfaces, to render them water and soil repellent. Volatile organic compound (VOC) free cream, paste, powder and solid compositions are provided by the inclusion of particulate stabilizers in the silicone compositions. Solventless silicone compositions provide numerous advantages with improved water and soil repellency qualities.
Claims77
A non-corrosive and physiologically acceptable composition for rendering surfaces water and soil repellent consisting essentially of
- a solventless intimate mixture of a silicone, an acid and a particulate solid, wherein said components are contained in relative amounts to provide the water and soil repellent properties and the acid is essentially sequestered to render the composition non-corrosive and physiologically acceptable to epithelial tissue.
A physiologically acceptable composition in the form of a cream, paste or powder for rendering surfaces water and soil repellent consisting essentially of
- an intimate mixture of a silicone, an acid and a particulate solid to form a cream, paste or powder, wherein said components are contained in relative amounts to provide the water and soil repellent properties and the acid is essentially sequestered to render the composition physiologically acceptable to epithelial tissue.
A process of rendering a surface water and soil repellent comprising
- treating the surface with an intimate mixture of a silicone, an acid and a particulate solid, said mixture in the form of a solventless composition, a cream, a paste or a powder, wherein said components are contained in relative amounts to provide the water and soil repellent properties and the acid is essentially sequestered to render the composition physiologically acceptable to epithelial tissue, and
- forming a water repellent and soil repellent coating on said surface.
A non-corrosive and physiologically acceptable composition free of volatile organic compounds (VOCs) for rendering surfaces water and soil repellent consisting essentially of
- an intimate mixture of a silicone liquid, an acid and a particulate solid, said mixture being essentially free of VOCs, wherein said components are contained in relative amounts to provide the water and soil repellent properties and the acid is essentially sequestered to render the composition non-corrosive and physiologically acceptable to epithelial tissue.
A method of making a storage stable physiologically acceptable composition in the form of a cream, paste or powder for rendering surfaces water and soil repellent comprising
- intimately mixing a silicone, an acid and an particulate solid for a sufficient time and at a temperature in relative amounts to form a storage stable cream, paste or powder, wherein the acid is essentially sequestered to render the composition physiologically acceptable to epithelial tissue.
