Definitions

  • the present invention relates to a high-viscosity silicone-based coating adapted to temporarily cover the surface of, for example, bathrooms and toilets, in order to reduce water consumption and cleaning times of the sanitary ware.
  • the invention also relates to a spray can containing therein at least the above- mentioned high-viscosity silicone and a propellant.
  • the method relates to the method of applying the aforesaid water- repellent/release coating.
  • this material is mainly composed of silane (SiH4), siloxane (siloxane, H3Si-(OSiH2)n-OSiH3) and a small amount of chelate, with the silane and siloxane containing 62-72% of silicon.
  • a repellent coating may be formed from such formulations on the substrate surfaces by drying the formulation on the surface to substantially remove the solvent and to form a bonded layer on the surface with the lubricant firmly adhered to the bonded layer.
  • the formulations can be applied to surfaces made of ceramics, glass, metals, alloys, composites, polymers or combinations thereof such as ceramic or metal sanitary ware, surfaces of glass substrates including mirrors, windshields, windows, surfaces composed of one or more polymers, medical materials (devices such as ostomy devices), etc.
  • solvents may include a lower ketone, lower alcohol, lower ether, lower ester, lower halogenated solvent and combinations thereof
  • lubricants may include a silicone oil or mineral oil or vegetable oil or any combination thereof.
  • Other components may be included in the described formulations, such as a fragrance.
  • silicone which is the main component of the water-repellent coating that will be described shortly, is also present in the document just described, but only as a secondary component of the lubricant; the result is a water-repellent film that is indeed temporary, but whose effectiveness, given its low viscosity, is rather poor.
  • the water-repellent and release coating subject of the present invention is intended to overcome the problems described in the state of the art, as it can be used on all installed and manufactured ceramics, particularly on the inner surfaces of bathrooms and toilets; it can also be easily applied in any type of environment for both large structures and home use.
  • a coating with a release effect can also be used on the inner surfaces of moulds, particularly for moulding plastics, in order to facilitate the release of the moulded part from the mould itself.
  • the main component of the coating is a high-viscosity single-component silicone and the best application method is by spray can.
  • the diluting action is thereby provided not only by the solvent used to dilute the silicone (e.g. alkanes, cycloalkanes or the like), but also by the propellant (liquefied hydrocarbons such as butane propane, dimethyl ether, etc., or even compressed gases such as CO2 and N2...) present in the spray can.
  • the solvent used to dilute the silicone e.g. alkanes, cycloalkanes or the like
  • propellant liquefied hydrocarbons such as butane propane, dimethyl ether, etc., or even compressed gases such as CO2 and N2
  • High-viscosity silicone is a rubbery material that has an advantageous tendency to self-repair and level even in spots where there may have been some small mechanical removals.
  • silicone is a polymer that contains a silicon atom combined with carbon, hydrogen and oxygen; sometimes other complementary groups may also be added.
  • POLYDIMETHYL SILOXANE i.e. the silicone oil used in this coating, where the silicon-bonded groups are METHYLS.
  • the number n describes the length of the polymer chain (or the degree of polymerisation). As n increases, the viscosity of the product increases from 0.65 cSt (centiStokes) or mm 2 /s to over 20,000,000 cSt or mm 2 /s.
  • the viscosity value of the POLYDIMETHYL SILOXANE silicone, or mixture of silicones used for this invention is at least 500,000 cSt (centiStokes) or mm 2 /s, preferably above 20,000,000 cSt or mm 2 /s.
  • a hydrophobic (water-repellent), coloured and transparent film which has a release/anti-adhesive effect against faeces and liquids, is deposited on the surface of the toilet (or other similar surfaces). More specifically, in the case of liquids, the droplets tend to slide directly into the bottom of the toilet, thus not drying out and releasing unpleasant smells; in the case of faeces, cleaning, even after a long time, is mechanically facilitated and therefore easier and faster.
  • the application by spray can is the most effective and performing, but the product can also be used in other ways, such as spraying, brushing or dabbing.
  • the product therefore requires only one application; the surface is active and functional after about 5-10 minutes.
  • the deposited film is not permanent, as it can be easily removed by mechanical action or using detergents.
  • the use of such a product allows to reduce consumption of water and aggressive detergents, as well as reduce the time for cleaning.
  • the invention also relates to the spray can which comprises therein (filled with) a first predetermined amount of POLYDIMETHYL SILOXANE silicone, with a viscosity grade of at least 500,000 mm 2 /s, preferably higher than 20,000,000 mm 2 /s, and a second predetermined amount of propellant.
  • the spray can thus constituted is advantageously configured to allow a water-repellent/release coating according to the invention to be applied to an inner surface of a toilet or any other type of surface of any element.
  • the propellant is a liquefied hydrocarbon, such as butane propane and dimethyl ether, or alternatively a compressed gas, such as carbon dioxide and diatomic nitrogen.
  • a liquefied hydrocarbon such as butane propane and dimethyl ether
  • a compressed gas such as carbon dioxide and diatomic nitrogen.
  • a third predetermined amount of solvent is also placed inside the spray can of the invention.
  • this solvent is selected from alkanes, cycloalkanes or the like.
  • the composition within the spray can is the following:
  • the invention also relates to the method of applying the water- repellent/release coating of the invention.
  • This method provides in particular the following steps: a) thoroughly cleaning the surface onto which said water-repellent/release coating is to be applied; b) applying the water-repellent/release coating (3) onto the surface using a spray can containing POLYDIMETHYL SILOXANE silicone, with a viscosity grade of at least 500,000 mm 2 /s, preferably higher than 20,000,000 mm 2 /s, and a propellant, so that the solvent action is also provided by the propellant of the spray can itself; c) waiting for at least five minutes before using said surface to allow the dilution solvents present in said silicone to evaporate, allowing the formation of said water-repellent/release coating.
  • the step a) is carried out using detergents in order to completely remove the residues present on said surface.
  • the step a) of cleaning the surface is followed by an additional step of drying and removing moisture from the surface with a dry cloth.

Abstract
