A granular, organically-modified clay filtration/adsorption media for water treatment, OilSorb™ removes mechanically emulsified oil and grease, free oil and high molecular weight organic molecules. It is highly versatile, effective, and can be used in pre-treatment, post-treatment, or stand-alone processes.

Benefits of Use

OilSorb™ is a cost-saving filtration media - When used alone, OilSorb™ removes oil at 700% the rate of activated carbon and will reduce your operating costs by 50% or more. When used as a pre-treatment for activated carbon in applications involving oil and grease removal, OilSorb™ removes the oil and grease effectively, allowing the activated carbon to remove the soluble organic compounds more efficiently.

OilSorb™ increases the efficiency of the treatment process - The quaternary amine-treated clay pellets have the ability to capture 50 - 60% of their weight in oil, grease and other low solubility organic compounds. Used upstream from activated carbon or downstream of other oil removal processes, OilSorb™ optimizes the overall system performance and reduces costs.

OilSorb™ can be easily disposed of in a variety of ways.

Client Solutions = Chemical Selection + Customer Service

Chemical problem solving requires several factors working closely together:

• Demonstrated capabilities in well-defined areas of chemical manufacturing
• Engineering experience that can safely address chemical problem issues
• Commitment to creating client relationships, not just "making customers"

Chemical manufacturing versatility combined with family-business tradition at GFS has translated customer service into client solutions for over 70 years. For example:

GFS Chemical Manufacturing in Support of NASA Space Program In the 1960's when the NASA space program began to focus on the Apollo missions and the goal to retrieve and analyze lunar samples, GFS was asked to develop a process that would manufacture high purity acids having virtually no trace metal contaminants. By using specially designed quartz stills, we were able to provide NASA scientists with the highest quality acid available, including the perchloric acid needed to digest these unique samples. GFS continues to be a primary producer of Trace Metal grade acids used in all kinds of advanced analytical protocols.

Traditional GFS Amine Ligands Finding New Use as Chemical Sensors Many of the heteroaromatic amine ligands that were developed in the 1930's are now playing an important role in fiber optic and sensor technologies. Bathophenanthroline (4,7-diphenyl-1,10-phenanthroline) complexes of Ruthenium(II) have been engineered into a broad range of chemical sensing systems. In the 1990's, customers advised us that the growth of some technologies of considerable environmental impact depended upon the development of complexes having more favorable solubility in organic and polymeric matrices. In response, GFS chemists were able to manufacture a new, more soluble tetraphenylboron salt of (tris) Bathophenanthroline ruthenium(II) and make it available for chemical sensor research.

GFS Meets Special Needs for Pharmaceutical Process Chemicals Manufacturing pharmaceutical intermediates requires raw materials and reagents meeting especially tight specifications. Major drug companies have learned that GFS can manufacture many chemical products in ton lots to specifications more stringent that those described in the GFS catalog. Taking a 50 gram sample to commercial volumes in a few months goes a long way toward building the long-term client relationship that has been the tradition at GFS since 1928.

Commercial Markets also Benefit from GFS Client Solutions Several years ago GFS was approached about providing an active, hard-surface sanitizer that was needed in the beverage service market. At the time, GFS had no experience with the material and no facility designed to carry out the chemical manufacturing on large scale. Within six months, the GFS plant site was modified to create a facility that was approved by customer, EPA, and FDA, and we implemented a manufacturing process for this active ingredient that continues to this day.

Broader Manufacturing Capabilities = Better Client Solutions

GFS has greatly enhanced its chemical manufacturing capabilities in recent years. With increasing resources for R&D and for the development of both technical and safety information, GFS offers a broad range of Client Solutions on both the organic and inorganic sides of the business.

In some cases, the two chemical disciplines can be brought together to offer unique problem solving capabilities. GFS has been the primary supplier of anhydrous lithium perchlorate to the battery industry for decades. Now we are helping to develop new methodologies for complex chemical synthesis involving solutions of anhydrous lithium perchlorate and magnesium perchlorate in organic solvents such as diethyl ether or ethyl acetate. Commercialization of this technology offers many attractive possibilities in the manufacture of pharmaceutical precursors, agricultural intermediates, and in polymer synthesis. More information is available by subscription online from GFS, or as a monograph published by GFS in early 2002.

CLEVELAND, Ohio (May 25, 2007) – Sherwin-Williams Industrial and Marine Coatings Fast Clad ER® Epoxy Pipeline Coating provides improved edge retention and a faster cure time than conventional epoxies and allows pipeline coating repairs to be made quickly and easily, significantly minimizing downtime.

In addition to standard packaging, Fast Clad ER is also available in pre-loaded cartridge mixing systems which are ideal for easy repairs and small jobs -- reducing waste, and improving mixing accuracy.

Fast Clad ER Epoxy is an ultra high-solids epoxy amine coating that presents significant advantages over other epoxy coatings in pipeline rehabilitation and repair, such as excellent cathodic disbondment resistance, outstanding adhesion properties, ultra high solids that comply with all VOC regulations and first-rate edge build which improves overall corrosion performance.

"This one-coat, rapid-cure epoxy coating is capable of returning pipelines to back fill within six hours of application," said Doni Riddle, Vice President and Director of Sherwin-Williams Industrial and Marine Group. "A faster cure time means a quicker return to service. By making this coating available in a pre-loaded, easy to use cartridge, coating applicators can get the job done right, with improved efficiency."

Ideal for petrochemical facilities such as oil refineries and chemical plants, this low-odor, equal parts mix ratio reduces waste, improves mixing accuracy and provides superior anti-corrosive protection essential for pipeline coating success. Designed for plural-component application equipment, Fast Clad ER Epoxy is recommended for use over prepared steel surfaces, suitable in any petrochemical facility.

The high sag resistance properties present in Fast Clad ER Epoxy provide superior protection comparable to conventional epoxies, while still maintaining a shorter cure time, says Riddle. When applied at 20.0 mils wet at 50% relative humidity, the 98% solids tank lining is dry to touch in one hour and can be walked on within four hours.

Fast Clad ER Epoxy is available in white and turquoise green colors.

Allied's Materials Research and Development laboratory successfully optimized ingredients to create a formulation with the ability to resist the effects of UV degradation. The formulation was developed through the effective use of UV absorbers that provide protection by physically absorbing light in specific ranges of wavelengths, HALS (Hindered Amine Light Stabilizers), and antioxidants. Together, all three classes of stabilizers provide specific protection to modes of failure associated with outdoor exposure.

Allied Moulded's new Ultraguard® formulation, while retaining its already robust structural integrity, now has an enhanced surface finish with improved aesthetics. Based upon customer feedback, Allied Moulded recognized an increased number of customer applications requiring outdoor capability and the related challenges to non-metallic enclosure designs. This is why Allied Moulded chose to invest in continuous improvement of our material formulations. Customer applications often require enclosures to be mounted on expensive systems where aesthetic appearance is critical. Changes in enclosure color, texture, and gloss in these applications are not acceptable. Fiberbloom, for example, not only is aesthetically unattractive, but can also be an issue if people come in physical contact with the enclosure surface. Literally defined, fiberbloom is degradation of the polyester compound surface during long-term outdoor exposure, resulting in the eventual exposure of glass fibers. Fiberbloom does not affect the structural integrity or NEMA rating of the enclosures.
