Covia

Covia provides a broad array of high-quality minerals and material solutions for the industrial and energy markets and a comprehensive and accessible distribution network. 

The company produces a wide range of specialized silica sand, feldspar, nepheline syenite, calcium carbonate, clay and kaolin products and has unique expertise in areas such as micronization, resin development, and coating and blending. Covia’s odor-neutralizing, dust suppressant, and low-emission technologies help to support your company’s Environmental, Health & Safety (EHS) goals.

MINEX® fillers are produced from Nepheline syenite, a naturally occurring sodium-potassium-aluminum silicate without reportable free crystalline silica. MINEX micronized functional fillers and extenders are proven performance enhancers in a broad range of paints, coatings, adhesives, sealants, and inks. Multiple grades are available to provide optimal performance in a variety of applications.

The selection of the most suitable MINEX grade is application dependent: coarser grades offer cost effective gloss and sheen control and can add texture; finer MINEX grades are preferred for higher gloss systems and are also the preferred choice for powder coatings and clear systems.

IMSIL® Microcrystalline silica fillers are produced from an inert, naturally occurring alpha quartz with a unique grape-like morphology. Easily wetted and dispersed in either solvent or water-based systems, IMSIL is selected for its excellent tint retention, durability over prolonged exposure, and resistance to dirt and weathering.

Interior architectural paints formulated with IMSIL will exhibit strengthened film integrity, increased stain resistance, more uniform sheen control, and excellent “touch-up” characteristics. Low oil absorption, regardless of particle size, enables formulators to increase loading without adversely affecting critical film properties. Exterior coatings containing IMSIL will better resist weathering, chalking, and under eave frosting. When used in primers, IMSIL also provides the “tooth” necessary for better intercoat adhesion and greater durability in abrasive or corrosive environments. IMSIL has been proven effective in trade sales paints, OEM finishes, marine and industrial coatings, and potting compounds. Finer, micronized grades are useful in formulating higher gloss paints, and systems requiring controlled mineral top size, such as thin coatings and inks. Coarser grades offer texture, traction properties, gloss control, and abrasion resistance in coatings, grouts, sealants, and related building products.

All IMSIL grades are processed with rigid adherence to Covia QIPSM statistical and quality assurance programs. The result is chemical purity and consistently uniform particle size distributions for predictable results and reliable service.

Flexible plastic films, like those used in food packaging, are refined using Covia’s HC series MINBLOC anti-blocking agents, which offer excellent clarity and in clear polyolefin films. MINBLOC engineered thermal fillers have thermal, optical and other properties that set them apart from other thermal fillers.

Thanks to their durability, insulation, safety, and low maintenance requirements, Covia’s HIFILL (calcium carbonate) and HIFILL N (nepheline syenite) are ideal for outdoor construction, including decking, vinyl siding, window and door profiles, and fencing. A unique all-natural sodium–potassium–aluminum silicate mineral HIFILL® N additives are available in ultrafine, precisely controlled particle size distributions for optimum performance. HIFILL® N allows for formulation and processing cost reduction while not adversely impacting the products’ physical properties and durability.

These are the same products formerly made by Sibelco.
