Silica Binder Technology |
|
|
|
One of the challenges that researchers face today in developing nano-sized photocatalysts or anti-microbial materials is to find a delivery system or binder to hold the new material in place without degrading the desired performance of the new material.
All surfaces, including glass, polycarbonates and stainless steel, may appear flat, but in fact they have minute bumps and indentations that cannot be seen. Using our binder technology, it is now possible to bind to virtually any material by making use of a variety of silica particles between 5 and 30 nanometers in size. And because we are using very small particles of silica, those particles that must be exposed to the surface to be effective such as the photocatalyst titanium dioxide or the static-electricity reducer tin oxide are easily able to reach the surface to achieve a high rate of functionality. |

Unqiue properties of Silica Binder |
|
|
|
1) Highly adhesive coating that adheres whether substrate is organic or
inorganic.
2) Extremely safe, reliable and long-lasting because it is inorganic.
3) Highly transparent because it uses nano-sized silica particles (5~30nm).
4) By controlling the placement of the silica particles, we are able to
ensure that adequate portions of the photocatalyst, for example, break
through the surface and provide the photocatalytic effect. Please note
that if a product’s binder is not effective, the binder itself may cover
the photocatalyst and reduce the catalytic effect.
5) Ease of application. A very uniform coat can be obtained by applying
with a specialized spray gun. |

What is Antimony-doped Tin Oxide? |
|
|
|
A durable element with high level of chemical stability that reduces static electricity (by increasing surface conductivity) and creates a dissipative surface with surface resistance of 10^8 onms per square. |

What causes static electricity? |
|
|
|
Static electricity occurs when there are an excess of positive (+) or negative (-) charges on an object's surface.
Most matter is electrically neutral. That means its atoms and molecules have the same number of electrons as protons. If a material somehow obtains extra electrons and attaches them to the atom's outer orbits or shells, that material has a negative ( - ) charge. Likewise, if a material loses electrons, it has an excess of positive (+) charges. The electric field from the excess of charges then causes the electric effects of attraction, repulsion or a spark (lightning).
Usually, substances that don't conduct current electricity (insulators) are good at holding a charge. These substances may include rubber, plastic, glass or pitch. The electrons that are transferred are stored on the surface of an object. The ability of material to surrender its electrons or absorb excess electrons is purely a function of the conductivity of the material with which you are working. For example, a pure conductor, such as copper, has a rigid molecular construction that will not permit its electrons to be moved about freely. A purely non-conductive materials, such as plastics, it is extremely easy to disrupt the molecular construction and cause the material to charge with the slightest friction, heat or pressure.
Adding surface conductivity to processed materials will move them up into the higher conductivity range and prevent the build up of static electricity.

What is Silver Ions? |
|
|
|
Silver, a natural anti-biotic, is known to possess the power to sterilize and disinfect since ancient times and has been used for medicines and household goods. With advance nanotechnology, this sterilization effect is powered up. |
|
 |
|
How does Silver Ions work? |
|
|
|
When Silver Ions is in contact with bacteria and fungus, it will adversely affect cellular metabolism and inhibit cell growth, leading to death of bacteria. |
