Title: LIQUID COMPOSITION TO GENERATE A REMOVABLE TEMPORARY PROTECTION FILM, BASED ON AQUEOUS DISPERSIONS OF POLYURETHANE
Abstract:
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.
