Rhino Shield New England™- About 3M Ceramic Microspheres

03/09/2010

Ceramic microspheres were invented in the early 1960’s by the 3M Company as an outgrowth from the manufacture of solid ceramic beads. Because the microspheres are made of ceramic, they provide the additional benefits of high heat and chemical resistance.

The central air pocket in the microspheres provides an insulating barrier for your walls much like a thermos bottle does. This insulating, industrial maintenance-free coating is long lasting, offering superior mildew resistance, corrosion resistance, and ultra-violet ray reflectivity.

Rhino Shield’s 3M Ceramics incorporate different sized microspheres as fillers. Conventional paints utilize inexpensive mineral products as fillers that are irregular in shape and size. These irregularly shaped fillers don’t pack nearly as well as a mix of small and large microspheres. (The smaller spheres pack more tightly into the spaces between the smaller spheres.) The more densely the coating is packed with microspheres, the less permeable it is to stains and the thicker it is when dry.
