Sand Colorant: Color Sand, Quartz & Glass Beads

Sand colorant & coloringAgriCoatings produces sand colorant and systems to color sand, quartz, glass beads and more. Colored sand and quartz are widely used to accentuate the color of architectural products like seamless epoxy flooring, tile grout, and swimming pool plaster. These applications require rugged durability and long life under demanding circumstances.

American Colors has created a line of aqueous quartz and sand colorants with durability to match the demands of the end use. Sand coloring also finds use in artistic and creative applications where bright colors and eye-catching shades are more prominent. Glass beads, or microspheres, can be coated in a similar fashion with excellent results.

The raw materials used in our quartz and sand colorants are chosen specifically for their properties. The base polymeric resin provides excellent chemical and abrasion resistance when cross-linked and fully cured. Lightfast grades of pigments are used wherever exterior durability is needed, and a wide range of shades is possible.

The limited film thickness of our sand colorant on each granule results in a somewhat translucent coating. This can be advantageous depending on the color and clarity of the sand or quartz grade being coated. The best results come from applying our sand coloring to a white or nearly clear granule. The lighter granules impart less color and result in cleaner more chromatic shades. Using a darker granule will likely impart some color and slightly diminish the resulting hue of the sand colorants used.

The additive package within our sand colorant is designed for optimum adhesion to sand and quartz providing for durability in demanding applications.  To maximize the full potential of our product certain manufacturing guidelines should be followed. The sand or quartz granules to be colored must be clean, dry, and as free of dust as possible. Fine dust and stray particulate can consume a portion of the coating that was otherwise intended for the larger granules. This can result in a less vibrant color and a noticeable increase in color demand.

A typical use rate for our quartz and sand colorants ranges from 0.75% -1.0% on the weight of sand or quartz. Some form of tumbling or medium intensity mixing is recommended to distribute the coating on the granules. For best results forced air drying is recommended while some mixing continues to prevent blocking. Drying without movement can result in the granules adhering to each other and forming a solid block of material.
