DEPOSITION OF PROTECTIVE COATINGS ON SUBSTRATE SURFACES

摘要

A solvent system for depositing a coating material onto a solid substrate surface, which solvent system is comprised of at least two organic solvents wherein at least one of the solvents has a substantially different vapor pressure that at least one other solvent in the solvent system. This invention also relates to a method for depositing thin films on substrate surfaces using a solvent system comprised of a blend of at least two organic solvents having substantially different vapor pressures. In a preferred embodiment the solvent system is comprised of effective amounts of n­propyl bromide and 1, 1, 1, 3,3 -pentafluorobutane.
