Title (EN) LIQUID COMPOSITION TO GENERATE A REMOVABLE TEMPORARY PROTECTION FILM, BASED ON AQUEOUS DISPERSIONS OF POLYURETHANE
(FR) COMPOSITION LIQUIDE PERMETTANT DE PRODUIRE UN FILM DE PROTECTION TEMPORAIRE AMOVIBLE, À BASE DE DISPERSIONS AQUEUSES DE POLYURÉTANE
Abstract:
(EN) The present disclosure describes a removable temporary protecting film, engendered from a liquid composition, formulated by aqueous dispersions of polyurethanes, wax, release agents, cross-linking agents, ultraviolet stabilizer agents, thickening agents, filler agents, and additives. Such film is used to temporary protect polymeric or metallic substrates, either coated or not, and ceramic and glass substrates from light scratching, some chemical products, dust, and water. Likewise, the temporary protective film, engendered from a liquid composition can be easily peeled out from metallic substrates, either painted or not, plastic objects in general and chromed pieces. Such liquid composition can be applied following conventional aspersion or immersion procedures, or by the use of a brush o roll.
(FR) La présente invention concerne un film de protection temporaire amovible fait à partir d'une composition liquide comprenant des dispersions aqueuses de polyurétanes, de cire, d'agents de décollage, de réticulants, de stabilisants aux UV, d'épaississants, d'agents de charge, et d'additifs. Un tel film sert à protéger temporairement les substrats polymères ou métalliques, qu'ils soient enduits ou non, ainsi que les substrats de céramique ou de verre contre les rayures légères, certains produits chimiques, la poussière et l'eau. De la même façon le film de protection temporaire, produit à partir d'une composition liquide, peut facilement se décoller des substrats métalliques, peints ou non, d'objets en plastique en général, et des pièces chromées. Une telle composition liquide peut s'appliquer par des procédures conventionnelles d'aspersion ou d'immersion, ou au moyen d'un pinceau ou d'un rouleau.
