Abstract Details

2005, MS, University of Cincinnati, Engineering : Materials Science.
This work deals with the development of a non-chromate, one-step finishing system for corrosion protection of hot-dip galvanized steel. Environmental regulations demand that chromate pretreatments and chromate pigments used in primers be replaced. In this project a pretreatment-free, chromate-free one-step finishing system was needed for hot-dip galvanized steel used in automotive coils in cars. Pretreatments act as adhesion-promoters and bind coatings to metals and since silanes, especially systems using bis-amino silane and bis-sulfur silane, have been shown as excellent adhesion-promoters by this lab, the idea of incorporating silanes in primers for obtaining adhesion to metals emerged. Whether this also meant increased corrosion protection was investigated. It was clear from the performance results and characterization experiments that silanes perform positively, in terms of enhanced corrosion protection of the metal substrate and adhesion. The polyurethane network resulted from the curing agent-resin reaction. A chromate-free, one-step finishing system without need for pretreatment and exhibiting enhanced corrosion protection and adhesion to metal was developed.
