Title (EN) METHODS OF BLOCKING STAINS ON A SUBSTRATE TO BE PAINTED, AND COMPOSITES SUITABLE FOR USE IN SUCH METHODS
(FR) PROCEDES POUR MASQUER DES MARQUES SUR UN SUBSTRAT A PEINDRE ET COMPOSITES POUVANT ETRE UTILISES DANS CES PROCEDES
Abstract: front page image
(EN)Methods of blocking stains on a substrate to be painted are disclosed, as are stain-blocking composites that are useful according to the disclosed methods. In a broad aspect, the methods include the steps of contacting a stained portion of the substrate with a dry film layer; applying pressure to the dry film layer to cause the dry film layer to adhere to the stained portion of the substrate and to at least a portion of the substrate adjacent the stained portion of the substrate; and subsequently coating the dry film layer and the adjacent substrate with one or more additional liquid coating layers. Stain blocking composites useful according to the methods described include a release layer, to which the pressure is applied; a dry film layer, that can be clear or pigmented, that serves to block the stain; and an optional adhesive layer, intended to assist in adhering the dry film layer to the stained portion of the substrate and to at least that portion of the substrate adjacent the stained portion of the substrate.
(FR)L'invention concerne des procédés pour masquer des marques sur un substrat à peindre, ainsi que des composites de masquage de marques pouvant être utilisés dans ces procédés. De manière générale, ces procédés consistent à mettre en contact une partie du substrat couverte de marques avec une couche de film sec, à appliquer une pression sur cette couche pour qu'elle adhère à ladite partie du substrat et à au moins une zone du substrat adjacente à ladite partie, puis à recouvrir la couche de film sec et le substrat adjacent d'une ou de plusieurs couches de revêtement liquide additionnelles. Les composites de masquage de marques pouvant être utilisés dans lesdits procédés comprennent une couche de séparation sur laquelle la pression est appliquée, une couche de film sec transparente ou pigmentée servant à masquer les marques, ainsi qu'une couche adhésive optionnelle destinée à favoriser l'adhérence de la couche de film sec à la partie du substrat couverte de marques et à la zone du substrat adjacente à ladite partie.
