Description

[0054] The invention will be better understood in relation with the figures where:

[0055] FIG. 1 is a schematic view of the arrangement of a multilayer material according to the invention.

[0056] FIG. 2 is a picture of a trolley handle covered with a multilayer material according to the invention;

[0057] FIG. 3 is a picture of a door partially covered with a multilayer material according to the invention;

[0058] FIG. 4 is a picture of a door handle covered with a multilayer material according to the invention;

[0059] FIG. 5 is a picture of a broomstick partially covered with a multilayer material according to the invention.

[0060] FIG. 6 is a picture of the tape where the disposable protective layer is partially removed.

[0061] FIG. 7 is a schematic view of the arrangement of a multilayer material according to the invention for sub surface protection.

[0062] According to FIG. 1, the multilayers adhesive material comprises a tie binding layer 2 taped to a substrate 1 thanks to adhesive surface 4. The active treatment layer 3, disposed directly on the layer 2, is external and covers entirely the substrate 1.

[0063] The multilayers adhesive material of the invention can be in form of a roll or in sheets of specific dimensions.

[0064] The ‘Tie binder’ 2 in this case is a type of pressure sensitive tape. To apply the multilayers adhesive material, the surface to be treated 1 is first cleaned from material that may affect the bonding of the ‘Tie binder’. Then the disposable protective film is removed (depending if in roll form or not) from the multilayers adhesive material that is spread over the surface to be treated, the substrate 2, for example by unrolling the roll of multilayers adhesive material, and then firmly and neatly pressed onto the substrate to ensure adhesion of the material to the substrate. The treatment layer is then the outer layer.

[0065] The multilayers adhesive material can further comprise a protective film, to protect the exposed adhesive side of the tie binding layer. In that case, the protective film is removed from the ‘Tie binder’ (2) and disposed of before spreading the material over the substrate. When the material of the invention is presented as a roll, a protective film may not be necessary.

[0066] The multilayers adhesive material can further comprise a protective film, to protect the exposed active layer from degradation or scratches during storage or transport. This film is advantageously removed after placement on the substrate.

[0067] The newly obtained ‘Surface (1)’ acts as an auto neutralizing and continuously anti-bacterial and anti-viral surface.

[0068] In other more demanding conditions, the ‘Tie binder’ can be a variety of bonding materials, that may be in liquid, solid, paste, or multi-component forms.

[0069] According to FIG. 7, the multilayers material 70 of the invention is made to protect as an antiseptic tape. The binding layer 72 has a adhesive surface 76 on which is applied an active treatment layer 73 having a smaller area than the adhesive surface 76. A neutral insulant layer (such as for example gauze or cotton) is applied onto the active treatment layer 73. Layer 74 is applied on the layer 72 opposite to the adhesive surface 76 to protect against elements or insure impermeability.

[0070] This multilayer 70 is applied on skin 71.

[0071] The ‘Tie binder’ 72 in this case is a type of pressure sensitive tape. To apply the multilayers adhesive material, the surface to be treated 71 (the skin) is first cleaned from material that may affect the bonding of the ‘Tie binder’. Then the multilayers adhesive material is placed over the surface to be treated, the substrate 71 and then firmly and neatly pressed onto the substrate to ensure adhesion of the material through surface 76 to the skin 71. The treatment layer 73, 75 is then against the skin.

[0072] The multilayers adhesive material 70 can further comprise a protective film (here not shown), to protect the exposed adhesive side of the tie binding layer before use. In that case, the protective film is removed from the ‘Tie binder’ 72 and disposed off before applying the material over the skin 71.

[0073] The multilayers adhesive material can further comprise a protective layer 74, to protect the exposed active layer from degradation or scratches during storage and protection layer against external elements.

[0074] The tape 70 here acts as an auto neutralizing and continuously anti-bacterial and anti-viral protection of the skin 71 in this case of application per FIG. 7 acts as a wound antiseptic dressing.

[0075] Tie binders are made to be used in such a way that they do not affect or reduce the performance of the desired and designed surface and act just as an inter-bond between two materials.

[0076] The ‘Tie binders’ are selected as per binding performance needs. Certain ‘Tie binders’ can be suitable with certain active ingredients and surfaces to be treated, and other ‘Tie binders’ are selected to be suitable to other active ingredients.

[0077] For more precision in application, the active ingredient(s) is applied onto the tie binding layer using methods such as: laser, electromagnetic, multi 3d, stamp, transfer, screen printing, CVD, or simple pressure.

[0078] In case a multi component is required, then these can be applied by various well-known application techniques and machines.
