Sunnen's New SHO-500 Honing Oil Added to USDA BioPreferredSM Online Catalog

Vegetable-based honing oil listed among more than 1480 biobased products

St. Louis, MO - The U.S. Department of Agriculture's (USDA) BioPreferred program, a Federal purchasing program for biobased products, has recently added Sunnen's new SHO-500 vegetable-based honing oil to its online product catalog - a searchable, user-friendly database used to find biobased products that meet BioPreferred program requirements.

Offering a breakthrough in oxidation stability, SHO-500 is formulated without additives that many find objectionable, such as sulfur, chlorine and fluorine. It is an ideal solution in honing applications where additives cannot be used, such as nuclear and some aerospace parts, or where company policies discourage use of fluids with such additives. SHO-500 is acceptable in all parts of the world and to all religions and cultures. It is suitable for use with conventional vitrified honing abrasives and metal-bond superabrasives. SHO-500 joins Sunnen's two other planet friendly oils, MAN-863 and KG3X, as BioPreferred(TM) products. The new oil is available in 5-gallon (18.9 l) pails, 55-gallon (208.2 l) drums and 330-gallon (1,249 l) totes.

"We're pleased to qualify the SHO-500 vegetable-based honing oil for addition to the BioPreferred list," said Chuck Korn, product engineer at Sunnen. "These oils help reduce manufacturing's impact on the environment, and we're confident that customers willing to make the switch to a 'green' fluid will find its performance to be comparable to their conventional honing oils."

BioPreferred is a Federal program that seeks to increase the purchase and use of biobased goods - products made from biological or renewable materials.

"Initially, the catalog was created to help Federal procurement officers identify biobased products that qualify for preferred purchasing," said Ron Buckhalt, BioPreferred's program manager. "But the BioPreferred online catalog is accessible to anyone who wants to search for biobased products. We are gratified so many find the catalog a useful tool."

Biopreferred's online product catalog is searchable by product category (i.e. construction and road maintenance, housewares and cleaning products, etc.) and further by subcategory, manufacturer name or product name. Today, more than 1480 biobased products manufactured by more than 320 companies are in the online catalog, with new products continually being added. SHO-500 honing oil is listed in the catalog's Metalworking Fluids category under the Straight Oils subcategory.

About biobased products

As defined by Farm Security and Rural Investment Act of 2002 (FSRIA), "biobased products" are products determined by the U.S. Secretary of Agriculture to be commercial or industrial goods (other than food or feed) composed in whole or in significant part of biological products, forestry materials or renewable domestic agricultural materials, including plant, animal or marine materials.

About BioPreferred

BioPreferred was created by the Farm Security and Rural Investment Act of 2002 (2002 Farm Bill), and expanded by the Food, Conservation, and Energy Act of 2008 (2008 Farm Bill) to increase the purchase and use of biobased products. The U.S. Department of Agriculture manages the program. BioPreferred includes a preferred procurement program for Federal agencies and contractors, and a voluntary labeling program for the broad scale consumer marketing of biobased products.
