Abstract
The effect of treating the surfaces of filler or pigment particles on the water vapor permeability, water absorption, and adhesion between such surfaces and selected organic vehicles was determined. In addition, the effect of surface treatments on specific echanical and electrical properties of coatings under ordinary and hyperenvironme tal conditions was investigated. Coatings formulated from 3 different resins and 5 fillers were considered. A significant increase in the tensile strength of coatings containing trea e filler was observed. There was also an improvement in the dispersion of fillers in organic binders as a result of treating the filler with an organo-silane. The films cast from such formulations were noticeably smoother and more uniform. Water vapor permeability, water absorption, and other physical properties were not significantly affected by treating fillers before incorporation in the resin and preparation of films.
