SISTEMAS DE CAPAS ABSORBENTE DE CALOR

Sistema de capas absorbente de calor, que contiene al menos una primera capa (A), una segunda capa (B) y una tercera capa (C), en el que la capa (A) contiene absorbente de radiación ultravioleta pero no contiene ningún absorbente de radiación infrarroja, la capa (B) contiene absorbente orgánico de radiación infrarroja y absorbente de radiación ultravioleta y la capa (C) es una capa interferente reflectante en el intervalo del infrarrojo. Providing a new heat absorbing layer system having outstanding long term weathering resistance, and high transparency, glaze and heat resistance. Providing a new heat absorbing layer system containing at least one layer (A), a second layer (B), and a third layer (C), where layer A contains an IR absorber, layer B an organic IR absorber and a UV absorber, and layer C is an IR reflecting interference layer has outstanding long term weathering resistance, and high transparency, glaze and heat resistance. Independent claims are included for: (1) preparation of the layer system by coextrusion, multi-component injection molding, back spraying (sic), spraying on, adhesive bonding and/or laminating the individual layers A, B, and C, and if necessary other layers like the substrate (S) were prepared; (2) a profiled body containing the above layer system.
