September 9 Webinar - Alternative Products: Release Agents for Parts Manufacturing, Concrete Stamping and Asphalt Manufacture and Application
July 14, 2014
Date: Tuesday, September 9
Time: 2 PM ET
(Hosted by WSPPN & NPPR as part of the Safer Chemistry Challenge Program Fall Webinar Series)
In some manufacturing operations, various substrates are used to manufacture parts which are molded into a particular form. Mold release agents are used to prevent the fiberglass or plastic from sticking to the mold. Concrete and concrete overlay stamping involve stamping a pattern into concrete to give it the appearance of stone. Release agents are used between the curing concrete and the mats with the pattern to be stamped to prevent the concrete from sticking to the mat. A release agent is also used in asphalt manufacturing plants and when asphalt is being applied to roads to prevent the asphalt from building up and sticking to equipment and tools.
EPA Region IX and the South Coast Air Quality Management District (SCAQMD) sponsored a project conducted by the Institute for Research and Technical Assistance (IRTA), a nonprofit organization, to identify, develop, test and demonstrate low-VOC, low toxicity alternatives to the high VOC content materials used as release agents in these applications.
IRTA tested and demonstrated alternatives including water-based release agents, petroleum based lubricants, lubricants based on soy, and vegetable oil containing soy and canola oil recycled from restaurants. IRTA analyzed and compared the cost of using the alternatives. The project has been completed and the SCAQMD plans to develop regulations requiring the use of low-VOC alternatives over the next year or so.
Dr. Katy Wolf will present the findings of IRTA’s alternatives product research project and provide a comparison of alternative release agents.
