Method of spray polyurethane application utilizing internally mixed components applied with a flat fan spray

摘要

A method of spray forming articles with a nozzle that sprays in a flat fan-shaped spray pattern. The process may be used to form articles from a polyurethane composition. Repeated passes of the nozzle that partially overlap apply a deposit in a series of parallel paths. A primary flat fan-shaped spray is flanked by a pair of secondary sprays that are outboard of the primary spray. The secondary sprays facilitate feathering the edges of adjacent deposits and provide a spray application having a consistent thickness.
