Description:
ANTIMICROBIAL AND ANTIBACTERIAL ELECTROPHORETIC LACQUER (INSULATING VARNISH) COATING

TECHNICAL FIELD

This invention is related to antimicrobial and antibacterial electrophoretic lacquer coating which is used on hardware and ironmongery products such as door handles and grabrails, and on ornaments and personal items such as watches and rings, and on metal surfaces used in furniture production, and which makes contribution to human and public health by preventing such formations as viruses, bacteria and microbes thanks to its antimicrobial features. PRIOR ART

Electrophoretic lacquer coating is a coating component which is employed in many fields from hardware and ironmongery products such as door handles and grabrails to ornaments and personal items such as watches and rings, and from balustrades to metal surfaces used in furniture, and is applied on materials coated by all types of metals, and protects against oxidation and increases resistance.

Electrophoretic lacquer coatings used commonly in our day do not have a composition preventing such formations as bacteria and viruses and do not, therefore, make any contribution to prevention of pandemic diseases infested by inhalation and contact such as SARS, MERS and Covid-19 presently constituting a serious threat on human and public health. Components as door handles, grabrails, balustrades and railings are the most commonly contacted places in daily life, and therefore, represent a great danger for infestation of infectious and contagious diseases. These surfaces are required to be disinfected as frequently as possible, but this is not at all times possible, and in addition, disinfectants containing alcohol and surface active chemicals corrode the lacquer surface and cause damage to the coating. Some studies have been conducted in connection with this subject, and in a national useful model registration application no. TR 2006/05635, a product named “Heat and moisture resistant, antibacterial handle” is mentioned. It is also stated that the mentioned product is related to heat resistant handles which ensure easy holding and carriage of enamelled cooking utensils such as pots and pans used in cooking and heating of meals and which eliminate the negative effects on health by preventing formation of bacteria and microorganisms. In a European Patent application, publication number EP1541650B1, a study dealing with “use in order to obtain a polyamide based powder and antibacterial coating” is described. Said study is stated to be related to use of a powder containing at least one polyamide of 97 to 99.8% by weight and a soluble ceramic with silver ions detained thereon of 0.2 to 3% by weight.

As a conclusion, the requirement for elimination of shortcomings and disadvantages of mechanisms and applications existing in the prior art and already being used as of today creates an obligation of making a development in the relevant technical field.

PURPOSE OF THE INVENTION

The present invention is related to an antimicrobial electrophoretic lacquer coating developed in order to eliminate the aforementioned disadvantages and to bring new advantages to the relevant technical field.

The purpose of the present invention is to ensure creation and production of an electrophoretic lacquer coating having antimicrobial characteristics. Another purpose of the present invention is to ensure achievement of antimicrobial surfaces in many fields from hardware and ironmongery products such as door handles and grabrails to ornaments and personal items such as watches and rings, and from balustrades to metal surfaces used in furniture, thanks to creation and production of an electrophoretic lacquer coating having antimicrobial characteristics.

Another purpose of the present invention is to ensure elimination of such formations as bacteria, viruses and microbes thereon, thanks to achievement of antimicrobial surfaces in many fields from hardware and ironmongery products such as door handles and grabrails to ornaments and personal items such as watches and rings, and from balustrades to metal surfaces used in furniture.

Another purpose of the present invention is to make sure that such components and surfaces of door handles, grabrails, balustrades and railings most commonly contacted in daily life are at all times and continuously kept hygienic, and to make a contribution to prevention of spreading of contagious diseases infested by way of contact, thanks to elimination of such formations as bacteria, viruses and microbes on said surfaces.

Yet another purpose of the present invention is to ensure reduction of healthcare expenses, thanks to contributions made towards keeping of said surfaces hygienic at all times and towards prevention of spreading of contagious diseases infested by way of contact.
