Abstract
A method of coating which involves applying to a surface a dispersion containing a main bonding agent and a temporary bonding agent. The main bonding agent is not film forming at room temperature. Next the continuous phase of the dispersion is permitted to evaporate or is driven off, followed by precipitation of the main bonding agent and the temporary bonding agent to form a porous powder layer on the surface. The temporary bonding agent bonds the main bonding agent to the surface. The porous layer is then exposed to a solvent which causes the particles of the bonding agents to flow together, and any excess solvent is removed.
