Abstract

Prodn. of thick-walled moulded articles by compressing curable duroplastic masses contng. curable synthetic resins, thickening agents, fillers, and optionally catalysts, in mouldings, and then curing, comprises (a) compressing the masses, which contain at least 80% wt. filler, in the moulds for a brief period, without effecting any considerable degree of cure, (b) removing the shaped articles from the moulds, and (c) curing the shaped articles outside the moulds, optionally by thermal treatment. The process enables thick-walled hollow articles of uniform high quality to be moulded from duroplasts contng. a higher filler content. Waste prodn. is minimised, lower pressures can be used, and more economical mould utilisation is obtained. The process is suitable for use with epoxy resins, polyurethane resins, phenoplasts, aminoplasts, unsatd. polyester resins, and curable acrylic resins.
