Abstract: A method of painting a substrate coated with an electrocoat, wherein the electrocoat includes an average surface roughness equal to or greater than 3 microns, includes applying a two-component sealer onto the electrocoat to form a film having a thickness of from 5 microns to 20 microns. The two-component sealer is partially cured by application of heat to a gel content of from 10 to 50 wt. %. Thereafter, a topcoat, typically including a basecoat and a clearcoat, is applied onto the two-component sealer. Both the two-component sealer and the topcoat are completely cured by application of heat.

Abstract: The invention relates to a process for pelletizing polymer melts, at above ambient pressure, in a pelletizing chamber into which a cutting apparatus has been inserted. In a first step, the pelletizing chamber is flooded with a gas which is inert toward the polymer melt and whose pressure is that at which the pelletizing process is carried out. The polymer melt is then injected into the pelletizing chamber. Finally, the gas is displaced from the pelletizing chamber via a liquid as soon as the polymer melt begins to flow through the cutting apparatus, this melt being cut into pellets.
