iChem® - TK113 introduction and properties

iChem® - TK113 antibacterial powder is a new functional inorganic powder composed of Si, Al, Ag and other elements. It is processed by special process and equipment through the patented technology owned by World-Prospect, aiming at antibacterial and antiviral purposes. Compared with the traditional inorganic antibacterial agents, the product not only has the characteristics of broad-spectrum antibacterial, antiviral, high-efficiency, long time effect, no biological resistance and so on, but also has less effective dosage, low comprehensive use cost and convenient use. Because it does not contain heavy metals, it is safe to human body, easy to use and environment-friendly.

Product features

AThe unique surface structure design can fully contact with bacteria and viruses, and can kill bacteria and viruses more effectively; Compared with the traditional silver ions and nano silver, its non mobility is a very significant feature, which avoids the potential risks of silver ions or nano silver to human body and environment;

BThe silver contained in the product can inactivate bacterial protein and viral RNA, thus effectively killing bacterial viruses;

CIt has broad-spectrum antibacterial and antiviral properties, and has no drug resistance;

DTheoretically speaking, it has permanent antibacterial activity without self consumption and long time effect life;

EEnvironmental friendly, no lead, antimony, arsenic, barium, cadmium, chromium, mercury, selenium and other heavy metals, safe and harmless to human body.

Product application

This product is a professional inorganic safety special antibacterial agent, which can be used in the following fields:

  • coating

    building interior and exterior wall, floor coating; automobile coating; powder coating, etc;

  • paper

    packaging paper, decorative paper, label paper, wallpaper and other antibacterial paper;

  • polymer materials

    widely used in all kinds of polymer materials;

  • textile materials

    antibacterial treatment of various textile fabrics;

  • non-woven fabric

    non woven fabrics used for masks, sanitary napkins, diapers, air conditioners, air purifiers, etc.

Usage method

AIn the coating, paper or polymer materials industry, it can be directly added to the customer's formula, and can participate in grinding or high-speed mixing. It is recommended to use about 1% (w / w) in the formula;

BIn the textile or non-woven fabric industry, we can provide special concentrated pulp, which can be used by customers after blending to the specified concentration according to the process. On-site technical support can be provided;

COn the basis of the recommended addition amount, it can generally reach the national standard or even 99.99% of the antibacterial and antiviral rate; according to the characteristics of different industries, the dosage can be adjusted according to the test results, so as to achieve better and stable antibacterial and antiviral effect with the least cost.


The unique controlled release non-dissolution out technology avoids the potential human enrichment and environmental hazards of silver ion and nano silver.
