NSF Summary "High Performance Environmentally Safe Metal Pretreatments"

This poster was presented at the the National Science Foundation SBIR Conference held in Baltimore May 6-9, 2014. The poster summarizes the Phase II project where Ecosil successfully developed a green, high‐performance metal pretreatment derived from advanced silane chemistry with a blend of propriety additives. The poster also describes the financial benefits and other advantages provided by the SILSBOND pretreatment product. The product has proven to be effective on hot and cold rolled steel, aluminum, stainless steel, and galvanized sheet. It can be used under a variety of water and solvent based paints, e-coat, and stainless steel.

Hybrid Pretreatment for Powder Paint Processes

This article was published in Powder Tough Magazine June 2013 and presents the results of SILSBOND, a phosphate and heavy metal free pretreatment, applied to various metals under several types of powder paint. This product has successfully been used commercially as both a pretreatment and as a chrome free sealer over both zirconium and phosphate pretreatment.

NSF SBIR Phase I Report: "High Performance Metal Pretreatments"

In this project we successfully developed a green, high‐performance metal pretreatment derived from advanced silane chemistry with a blend of propriety additives. The excellent anti‐corrosion and paint adhesion performance of SILSBOND on multiple metals has been demonstrated in various applications at Ecosil and in customer laboratories as well. Results of the study reveal that the active components readily deposit onto metal surfaces and form a self‐organized nano‐structured film that is 10‐50 nm thick. The unique film structure of SILSBOND enables it to become an effective replacement for conventional pretreatments, and further, to be more robust than current alternatives such as Zr‐based pretreatments.

SERDP Report: Wash Primer Replacement based on Chrome Free Technology 2011

This report details the technical progress of a 2-year research program funded by the Strategic Environmental Research and Development Program (SERDP). The overall objective of this project is to develop easily applied and environmentally acceptable “wash primers” used for field maintenance of field equipment. Wash primers used in repairs of military ground vehicles (ie DOD-P-15328D), contain hexavalent chromium (Cr6+) and 6.5 lb/gal VOCs (Volatile Organic Compounds) and HAPs (Hazardous Air Pollutants). These wash primers provide good adhesion of subsequently applied primers and topcoats, and the presence of zinc chromate enhances the paint adhesion and corrosion resistance of the coated metal systems. In addition, these wash primers are broadly compatible with metal substrates including cold rolled steel (CRS) and aluminum often used in DOD applications. Although traditional wash primers have excellent performance, their formulations are environmentally undesirable. This project evaluate the performance of environmentally safe replacement products that are chrome free and have low VOC levels.
