Microorganism is microscopic living organisms, can be single-celled or multi-cellular presence around us. They are so small in size and can not be observed with naked eyes.

Microorganisms include bacteria, archaea, most protozoa, fungi, algae and rotifers. These microorganisms can benefits us but a small part of them may be harmful to human body. Those harmful microorganisms are categorized as pathogenic microbes/bacteria.

It is therefore necessary to control the growth of pathogenic bacteria and possible to eliminate them before it enter the human body.

Sanitize by WELT

“Quats” is the nickname used for quaternary ammonium compounds. Their disinfectant properties have been recognized for nearly 100 years. Quats have a common molecular structure. Changing the basic molecule changes the characteristics of the compound and gives quats the ability to be used in a wide variety of household, institutional, and industrial products. These products range from disinfectants, sanitizers, and cleaners to wood preservatives, fabric softeners and personal care products. Quat-based disinfectants and sanitizers are used in medical facilities, food service operations, water treatment, and many industrial applications. They are also used to control algae in ponds and other aquatic environments.

Titanium dioxide photo-catalyst as active ingredient is internationally recognized as one of the new sterilization materials which can kill almost all kinds of bacteria and some commonly seen viruses including flu and SARS. It has been widely used in places with high demand of sterilization like hospitals, institutions, schools, etc. Our nano structure modified nano titanium dioxide has strong effect on killing almost all kinds of bacteria under the irradiation of light and can remain efficient for long time and it thoroughly decompose bacteria, its body and the endotoxin. Meanwhile, photo-catalyst can wipe out the indoor allergen to reduce the incidence of respiratory diseases.

Silver ion (Ag+) has been widely used as anti-microbial agent since years ago. In the past, silver ion was deposited on to surfaces without secondary protection layer to ensure effectiveness. This has led to quick wash off of water-soluble silver ion which greatly cut down its service life. Our new technology has since solved the problem by controlling the release upon contact with moisture after deposition on surfaces with a coating layer. Silver ion released at a controlled rate provide long term protection to surfaces and at the same time safe to human and environment. It is normally incorporated into coating system which later painted on surfaces required protection against microbes. It can also be used as anti-microbial agent in cosmetics, water filters, air filters, plastic molding parts, rubbers, paint and coatings, etc…
