(FR) FEUILLES ACRYLIQUES PRÉSENTANT DES PROPRIÉTÉS DE PROTECTION CONTRE LES UV AMÉLIORÉES
Abstract
(EN)
The present invention relates to a transparent weathering resistant foil for protection of various substrates against solar radiation. In one embodiment of the invention the foil comprises at least two layers A and B, wherein the spectral transmittance of the layer A at any wavelength λA is not more than 10%; wherein 270 nm ≤ λA ≤ 360 nm; and the spectral transmittance of the layer B at any wavelength λB is not more than 10%; wherein 270 nm ≤ λB ≤ 370 nm. In a further embodiment of the invention the foil comprises at least two layers A and B, wherein the spectral transmittance of the layer A at any wavelength λA is not more than 20%; wherein 270 nm ≤ λA ≤ 310 nm; and the spectral transmittance of the layer B at any wavelength λB is not more than 10%; wherein 270 nm ≤ λB ≤ 370 nm.
