Definitions

• Nail polish on the other hand, is not what i expected.
• the plasticizers are required in order to give the coating obtained after the application and drying of the nail polish the necessary elasticity and sufficient adhesive strength on the nail surface.
• plasticizers have the disadvantage that they gradually "exude”, i.e. detaching itself from the coating This ultimately leads to the coating becoming porous, no longer adhering to the metal surface and finally chipping off. The protective function of such a coating is accordingly low.
• plasticizers are sometimes all genes themselves, which then trigger corresponding reactions on the skin.
• Measures which are suitable for protecting human skin when we come into direct contact with the surfaces of metallic objects are as little known as coatings, which are effective for protecting human skin when we come into direct contact with the surfaces of metallic objects. There is therefore no doubt that there is a great need for such measures or coatings.
• the object of the invention is therefore the production of metallic objects with effective protection against allergic reactions of the organism.
• the object is achieved in that a silicone as a coating is in direct contact with human skin Surfaces of metallic objects is used. Surprisingly, it was found that the silicone used in accordance with the invention leads to metallic objects which have an adherent and effective protection against allergic reactions.
• the silicone is applied to the surfaces of the metallic objects in direct contact with the skin in a thin liquid form and the coating thus obtained is allowed to air dry.
• the silicone is applied advantageously and preferably with a small brush or with a spray device, the silicone flowing onto the surfaces in question to form a coherent thin protective film.
• the application of the silicone coating is thus carried out in a particularly simple manner and nevertheless ensures that the coating extends into the corners, over edges and into the turns of the surface.
• the applied silicone coating adheres firmly to the surfaces concerned after drying and this represents a transparent and impermeable protective film.
• the plastic is also used here for a coating on metal surfaces, but that it has a completely different purpose in that it is not intended to protect against allergies from metal objects which are in direct contact with the skin, but rather the nails , Skin, etc. from allergies that come into contact with nickel particles that are contained in nail polish and come from metal objects that are not in direct contact with the skin.
• the problems that arise are very different to be judged as that of the present case.
• the plastic used as a coating is resistant to the solvents contained in the nail polish, not that the plastic does not trigger any allergic reactions on the skin (which, as is well known, many plastics do) , and simply not because the plastic does not come into direct contact with the skin at all.
• the selection criteria for the plastic are therefore completely different than for the plastic in the present invention.
• the silicone coatings adhere very well to the metal surfaces, although they do not contain any plasticizers, and that the plastic used for the coating is an allergen.
• the silicone used for the coating is a silicone rubber, namely a dimethylpolysiloxane with an addition of pyrogenic
• the density of the rubber at 23 ° C. was 1.066 g / ml and that Viscosity at 23 ° C, measured in a Brookfield rotary viscometer: 10,000 mPa s.
• the silicone rubber used is a commercially available product.
