Artificial urethane rock

摘要: A simulated rock produced by spraying a high density polyurethane elastomer in flexible rubber mold. The may be natural or synthetic rubber. is molded form, not limited size. mold prepared applying numerous coats of liquid uncured forming materials, such as latex rubber, upon the exterior combination with fabric embedded within layers. supporting cradle for low urethane foam composition over and are stripped from sprayed two component structural system employing an isocyanate polyol appropriate catalysts, fillers additives. built up to substantial thickness provide strong rigid load bearing simulating original surface curing taking place matter seconds minutes. After cooling, removed reused repeated molding operations. Where desired, reinforced inner layer reduce amount employed.
