Improved coating for hydraulic fracturing proppants
Two new coating products for sand proppants used in hydraulic fracturing operations in the oil and gas industry overcome the challenges of traditional phenolic coatings, which can leach environmentally hazardous chemicals. The coatings, developed by Preferred Sands LLC (Radnor, Pa.; www.preferredsands.com), are based on a specialized polyurethane developed over the past three years with partner The Dow...

This pipe-cladding process applies corrosion-resistant coatings faster
The surface engineering company MesoCoat, Inc. (Euclid, Ohio; www.mesocoat.com) recently started up a facility for manufacturing clad pipe for the oil-and-gas industry that uses the company’s proprietary fusion-cladding technology to apply corrosion-resistant alloys to carbon-steel pipes. Because the cladding can be applied to large areas at very high speeds, the technology can be used to coat much...

A low-cost route to ultrathin Pt films
Researchers at the U.S. National Institute of Standards and Technology (NIST; Gaithersburg, Md.; www.nist.gov) have developed a relatively simple, fast and effective method of depositing uniform, ultrathin layers of platinum atoms onto a surface. The technique may lead to a reduction in the amount of precious metal needed for catalyst applications, such as catalytic converters in automobiles and hydrogen...

This silicone coating keeps electrical insulators safe
Wacker Chemie AG (Munich, Germany; www.wacker.com) has commercialized a solvent-free coating for electrical insulators. Powersil 570 Plus is said to be the world’s first insulator coating based on a patented silicone-in-water emulsion technology. Its viscosity displays a strong dependence on its shear rate, which makes it...

Green honors
In June, the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) announced the winners of the 2011 Presidential Green Chemistry Challenge Awards. Winners of the Challenge, which promotes R&D of less hazardous alternatives to existing technologies that reduce or eliminate waste in industrial production, are selected by an independent panel convened by the Americal Chemical Soc...

Commercial production for a self-cleaning coating
Last month, PJI Contract Pte Ltd. (Singapore; www.pjicon.com.sg) opened a production facility for the manufacture of titanium dioxide solution — a self-cleaning, nanocoating material developed at Singapore Institute of Manufacturing Technology (SIMTech; www.simtech.a-star.edu.sg), a research institute of the Agency for Science, Technology...

Chementator: Bringing the corrosion resistance of tantalum to off-the-shelf stainless-steel parts

 

Tantaline (Lyngby, Demnark; www.tantaline.com) has developed a process that creates a surface alloy of tantalum on a metal substrate (typically stainless steel). As a result, the surface acquires the corrosion resistance of tantalum — the most corrosion resistant metal commercially available — without having to fabricate complicated parts from the expensive metal. Unlike alternative...
