The invention relates to a method for adhering two substrates, namely a first substrate A and a second substrate B, to each other using a latent-reactive adhesive film with at least one latent-reactive adhesive film layer which has a thermoplastic component with a melting temperature T(melt), where 35° C.≦T(melt)≦90° C., said thermoplastic component containing functional groups that can react to isocyanate, and an isocyanate-containing component that is dispersed into the thermoplastic component in a particulate form and is blocked, microencapsulated, or substantially deactivated in the region of the particle surface. The particles have a start temperature T(start) of 40° C.≦T(start)≦120° C., wherein T(start)≧T(melt). A surface of the first substrate A is brought into contact with a first surface of the latent-reactive adhesive film, and a surface of the second substrate B is brought into contact with the second surface of the latent-reactive adhesive film. The adhesion is caused by heating the latent-reactive adhesive film to a temperature which corresponds to or is higher than at least the start temperature T(start). The invention is characterized in that at least the surface of the first substrate A which is brought into contact with the latent-reactive adhesive film is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film, and/or at least the first surface of the latent-reactive adhesive film which is brought into contact with the first substrate A is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film.

The present invention relates to a foam tape for a sound-absorbing tire, the foam tape including a release film; a tacky adhesive layer formed underneath the release film; a base film formed underneath the tacky adhesive layer; an adhesive layer formed underneath the base film; and a sound-absorbing material layer having a porous structure and formed underneath the adhesive layer, and the foam tape having enhanced adhesive force to a tire, and the present invention also relates to a sound-absorbing tire including the foam tape for a sound-absorbing tire.

A method of manufacturing decoration foils and a release layer and an adhesive layer of the decoration foil, and decoration foils manufactured by the same are revealed. First take waste containing polyethylene terephthalate (PET) to react with an alcohol and get a first product. Then the first product is allowed to react with a compound containing isocyanate group and polyol to obtain polyurethane (PU) material. The PU material obtained is used for manufacturing at least one of a release layer and an adhesive of decoration foils to get the decoration foil.

The present invention provides switchable adhesives comprising a mixture, in proportions by weight, of 20% to 98% of an adhesive, 2% to 80% of curable molecules and 0.05% to 10% of photoinitiator in which the weight proportion of the adhesive is calculated on the basis of its dry weight and wherein the adhesive includes an internal cross-linker for cross-linking the adhesive during drying to provide a cohesive strength of between 5 and 100 N/12.7×12.7 mm measured according to FINAT test method No. 18. Preferably, the adhesive and curable molecules are mutually soluble when dry, or the curable molecules and adhesive may be uniformly dispersed in each other. Preferably the amount of adhesive in the mixture is in the range 40% to 98% by weight, more preferably 60% to 95% by weight, even more preferably 70% to 85% by weight. Preferably the proportion of curable molecules in the mixture ranges from 2% to 60% by weight, more preferably 5% to 40% by weight, even more preferably 15% to 30% by weight. Preferably, the photoinitiator is present in the mixture in the proportions 0.5% to 5% by weight, more preferably 1% to 3% by weight. Such switchable adhesives are useful in medical dressings and other removable sheet products, and may be simply prepared by stirring the adhesive, the curable molecules and the photoinitiator together at room temperature.
