    DESCRIPTION

    BIOCIDE TRANSPARENT COATING FOR NON-POROUS SURFACES

    The present invention consists of compositions, method of use and final use of a transparent coating of aqueous-based polyurethane, with organic / inorganic additives, for use on non-porous surfaces with biocidal effect.

    SECTOR OF THE TECHNIQUE
     10
    This invention belongs to the health, food, etc. sector. in prevention of the proliferation of microbes, bacteria, viruses and yeasts that can produce cross contamination on surfaces.

    STATE OF THE PREVIOUS TECHNIQUE 15

    The use of biocides has been widespread by man in the history of mankind, the Romans themselves used silver metal containers to preserve water from possible contamination.
     twenty
    At present, biocides are used as additives in different industrial processes for the manufacture of objects with bacterial protection or disinfectants. The types of additives can be of two well-defined chemical typologies: Organic and Inorganic.

    The variables can be multiple, depending on the desired effect and microorganisms to combat, each manufacturer interprets the needs of the market and adapts the biocides and adapts products according to their technical / commercial interests and strategic markets.

    The reality of our society is that an engineer / architect type designer, does not know the real needs of medicine, provides two basic and simple solutions to the constructed surfaces. The first in walls and ceilings traditional paint and the second, in the rest of surfaces, smooth materials, non-porous and easily cleanable by traditional disinfectants. These materials can be PVC, stainless steel, melamine, ceramics, etc.
     35
    In the health sector, different industrial suppliers of construction materials, medical equipment and furniture are involved. Each company has a different strategic vision, it is materially impossible to provide all the construction and equipment elements with suitable bactericidal additives to prevent the proliferation of biofilm in sanitary areas and / or food industries. We can add even other sectors 5 susceptible to bacterial protection such as: passenger transport vehicles or continental or intercontinental food such as ships, trains, airplanes, etc.

    BRIEF DESCRIPTION OF THE INVENTION
     10
    The present invention aims to establish a method to permanently protect the various non-porous surfaces of any type of construction element or equipment, by means of a coating that is applied in a liquid state and hardens in contact with the air offering a transparent appearance, practically unnoticed by the human eye once hardened, and acted as an inhibitor of microorganisms and / or 15 microbes.

    The composition of this coating may be of water-based polyurethane, water-based polyurethane-acrylic or water-based acrylic, modified with organic and / or inorganic biocidal agents. twenty

    The characteristics of this coating are: high adhesion on non-porous surfaces and its high transparency.

    The application of this coating can be done by brush, roller, fogging, or by spray gun electric / pneumatic.

    The purpose of this biocidal coating is to inhibit the proliferation of biofim and / or proliferation of microorganisms type: Gram positive / Gram negative bacteria, fungi, viruses or yeasts. 30
    权利要求:
    Claims (1)
    [1]

    1- Transparent biocidal coating to inhibit the proliferation of microorganisms and / or microbes type: Gram positive / Gram negative bacteria, fungi, viruses or yeasts on non-porous surfaces of construction elements, equipment and furniture. 5
    2- Coating according to the first claim characterized in that the composition can be made of water-based polyurethane, water-based polyurethane-acrylic or water-based acrylic.
     10
    3- Coating according to first and second claim characterized in that the biocidal agent incorporated in the composition can be of an organic, inorganic nature and / or dispersion of both.
    4- Coating according to any of the preceding claims characterized in that the density of the coating in liquid state is 0.5 g / cm3 to 1.8 g / cm3.
    5- Coating according to any of the preceding claims characterized in that the coating performance is from 10 gr / m2 to 500 gr / m2.
     twenty
    6- Coating according to any of the preceding claims characterized in that the application of this coating can be carried out by brush, roller, nebulization, electric gun and / or pneumatic spray.
