Abstract

The present work was aimed at the development of new organosilicate polymeric composite, based on polydimethylphenylsiloxane/polyurethane (PDMPS/PU) miscible blend, filled with silicates and metal oxides. Considerable improvement of mechanical and corrosion-protective properties due to introduction of polyurethane has been observed. Coatings with sufficient thermostability (up to 300°C) have been obtained in the case of 20% polyurethane content, related to amount of binders. The effects coating heat treatment temperature and curing conditions on adhesion of metal/composite interface have been studied. Surface energy characteristics of this coating have been obtained and were correlated with its microstructure, determined from Scanning Electron X-ray Microprobe Analyses. Recently developed composite appeared to show increased durability in atmosphere operation conditions.
