The resulting red granules are fully comparable, commercially speaking, to similarly colored red pigmented clay-silicate coated granules fired at much higher temperatures (as is presently conventional) and have superior resistance to staining and blistering on the asphalt roofing in which the granules are embedded.
Corrosion of iron in water systems may be controlled by the addition of small amounts of sodium silicate, which deposits a thin protective film of silica on the metal. Coatings Sodium silicate solutions are used in making various paints and coatings, as well as for welding rods and roofing granules.

Jun 19, 2013· Abstract: This invention relates to a color stable pigment composition for coating hard mineral granules employed for weather surfacing asphalt roofing and siding shingles. The composition is a 40-60% aqueous slurry of pigment containing ferrosoferric oxide and a silicate/clay mixture which is suitable for coating the surface of the mineral granules.
The granules are divided into the required sizes and continuously blended with inorganic pigments and sodium silicate to guarantee colour evenness. The product is ceramicized in a rotating kiln at guaranteed very high temperatures (650°C). At the end of the ceramicization process GeoColor granules undergo various chemical processes.

The adhesion agent, when used on ceramic-coated roofing granules, is employed in the composition of the invention to an extent sufficient to promote granule adhesion to an asphalt-based shingle substrate. The amount of adhesion agent can vary depending on the composition of .
The liquid sodium silicate market in the U.S. is expected to grow at a moderate rate owing to increasing demand for the product in detergents, elastomers and catalyst industry. The region has significant number of raw material suppliers and geographical advantages in terms of the raw material availability, which is likely to have a positive impact on the market growth
The sodium silicate, however, is the high-temperature adhesive; the kaolin serves simply as a compatible high-temperature coloring agent. Some of these repair compounds also contain glass fibres to enhance their gap-filling abilities and reduce brittleness. Sodium silicate can be used to fill gaps within the head gasket.
may include copper tailing and may be used as granules in roofing and siding materials. Provided are methods of coating granules which may make the granules hydrophobic and bonding the hydrophobic granules to an asphaltic or bitumi nous substrate. Further provided are methods for producing colored granules which may have hydrophobic and adhesive
The U.S liquid sodium silicate market is expected to reach USD 657.9 million by 2024, according to a new report by Grand View Research, Inc. Growing demand for the product as an adhesive in pulp and paper, and cement industry is expected to drive growth over the forecast period
