A method of making an adhesive for an ice protection assembly includes mixing ferrous nanoparticles into the adhesive. Removal of the adhesive for ice protection assembly inspection or repair includes heating the ferrous nanoparticles in the adhesive to soften the adhesive and allow for easy removal or repositioning of the ice protection assembly.

A thermo-adhesive multilayer film based on thermoplastic polyurethane includes a barrier layer having a material with anti-dye migration properties selected from: ethylene vinyl alcohol copolymer, polyvinyl alcohol, polyvinyl acetate, polyamides, cellulose derivatives, polyvinylidene chloride and combinations. The barrier layer is interposed between two layers, each having a mixture of a thermoplastic polyurethane with a compatibilizing agent selected from: co-polymers modified with maleic anhydride, co-polymers modified with epoxy groups, co-polymers containing hydroxyl groups and combinations thereof. A decorative multilayer film includes the thermo-adhesive multilayer film and a further decorative layer, which provides an aesthetic effect. A process of co-extruding the layers obtains the thermo-adhesive multilayer film and the subsequent bonding thereof with the decorative layer obtains the decorative multilayer film. The decorative multilayer film decorates substrates in the field of textiles, clothing, footwear and accessories. A finished decorated article includes a substrate on which the decorative multilayer film is applied.
