Potters® Performance Materials business works closely with customers to provide value-added performance additives that uniquely improve customer formulations by lowering cost and increasing performance.

Our microspheres serve as functional additives in industrial applications such as weight-reducing fillers in plastics, polymers, and automotive body putties, as extenders in adhesives and paints/coating formulations, sensitizers in industrial explosives, electromagnetic shielding for electronic parts, and abrasive applications for cleaning and peening metal surfaces.

Remember SPHERES:

Driving Green Alternatives

Glass powders (100 mesh to 600 mesh) are widely used in C.A.S.E (coatings, adhesives, sealants and elastomer-polymers) markets as a crystalline silica free recycled functional filler. Other applications include anti-block, ceramics, glazes, and frit.

Glass sands (12 mesh to 100 mesh) are used in stucco, traffic markings, pool filtration, and many other applications where being white and transparent has advantages. The glass sands are also free of crystalline silica.

Leading Glass Powder Characteristics:

  • Free of Crystalline Silica
  • Inert/Corrosion Resistance
  • Abrasion Resistant

Conductive Particles

The family of Conduct-O-Fil® particles can provide lower cost and lower weight replacements to expensive pure silver and high density nickel powders used in consumer, industrial and military markets. Specific applications include adhesives, lacquers, coatings, lubricants, greases, gaskets and a host of EMI shielding solutions.

Conduct-O-Fil® particles are two component particles consisting of a specially chosen core material that is plated with a precious metal coating. At the center of the technology is the ability to provide highly controlled particles having various shapes, sizes, and distributions with exact and uniform deposition of metal to the particle surface. A wide selection of Silver, Nickel and Gold coated products are commercially available coated on a variety of inner core particles including: Aluminum, Copper, Nickel, Ferrite, Glass and others. Every product is engineered to meet the wide array of demands required by the conductive markets we serve.

Green Construction Materials

Custom-engineered, high performance, pozzolanic additives for use in cement, mortar, concrete, stucco, faux stone and related products.

Potters Industries is the leading manufacturer of glass powders meeting ASTM C 1866.
Recently ASTM recognized ground Glass Pozzolans in a new standard ASTM C 1866. The standard identifies two types of glass. Type GS is soda-lime glass (ACAS Grades) used to make beverage containers and plate glass windows. Type GE is E Glass (VCAS Grades) used to make fiberglass reinforcements. Both types of glass are very pure and quite reactive at the required particle size of 95% passing 325 mesh (about 4000 Blaine) The major difference between the two types is that type GE effectively mitigates alkali–silica reaction (ASR) for even the most reactive aggregates like the New Mexico and Spratt aggregates, whereas Type GS (ACAS Grades), while very pozzolanic, will not mitigate ASR due to a 12% alkali content.

VCAS™ Pozzolans (Type GE) are made from Vitrified Calcium Aluminio-Silicate material having low alkali content, consistent chemistry, uniform color and a wholly amorphous (glassy) state caused by rapid water quenching of the extruded molten material. After primary sizing and drying, the feed stock is finely ground and processed through high efficiency classifiers to produce a fine White powder with quality assured physical properties. The consistent chemical composition and tightly controlled particle size distribution offers excellent repeatability of properties in concrete applications. Currently, the VCAS™ patented technology produces pozzolans in three grades: VCAS™ Ultra 200, VCAS™ 140 and VCAS™ 160.

VCAS 160™ and VCAS™ 140 are commonly used in systems with low w/c ratio and steam cured or warm weather curing conditions where the lower reactivity associated with a 4000 Blaine product is sufficient for the application. VCAS™ 200 has a much finer particle size and has the reactivities normally associated with silica fume and metakaolin with the advantage of being White in color. All VCAS™ grades exhibit approximately 10% lower water demand than silica fume or metakaolin and can be used at cement replacement levels of up to 40%.

VCAS™ Pozzolans are “green” construction materials made from industrial by-products that help contribute to the sustainability of cement and concrete. VCAS™ Pozzolans use in concrete replaces an equal amount of cement resulting in energy conservation and CO2 emission reductions from cement manufacturing. For every ton of cement manufactured, about 3.5 million BTUs energy are consumed and one ton of carbon dioxide is released.

Type GS has two subcategories, Plate glass (ACAS Grades) and bottle glass. The ACAS Plate is very white and pure and contains no organic or label remnants. Bottle glass is consumer recycled, tan in color, and must be carefully cleaned to remove organics and label remnants.

Potters Industries has three types of glass pozzolans; Type GE Glass VCAS Grades, Type GS Plate glass ACAS Grades and HR 50 Fumed Nanosilica Glass, an extremely reactive, very white pozzolan to replace silica fume.
