Production process of durable coating makes a substrate of difficult hard coating esubstantial hard coating with common durable coating

摘要

"Production process of coating duru00e1velsobre a substrate of hard coating of hard coating coated esubstrato common coating durable.The present invention refers to sea a production process of a coating on substrates of mu00faltiplascamadas durable hard coating, taiscomo aluminum.The process includes the submission of dosubstrato hard surface coating to a stage of adhesion promoter, followed by the application of an intermediate layer of primerflexu00edvel,Which contains a polyester copolymer produced atravu00e9sde a polymerisation process in two stages.A camadasuperior corrosion resistant composition of revestimentotransparente is then applied on the intermediate layer paraproduzir durable coating of multiple layers on osubstrThe act of hard coating. If desired, the camadaintermediu00e1ria may be pigmented or can be applied in the formade one or more layers with patterns of different colors.Alternatively, one or more layers with patterns dediferentes colors (m) can be applied (s) on the camadaintermediu00e1ria before application of the upper layer resistant u00e0corrosu00e3o.If desired, the application of the upper layer resistenteu00e0 corrosion and the layers with patterns can be delayed by atu00e9doze weeks, to allow the user to produce massacomponentes coated.Such as utilities deentrega bodies, with an intermediate layer of basic color, as white, which can then be specifically covered comdiversos standardized designs,Followed by the application back more resistant to corrosion.
