Protective organosilicon coating with significant oleophobic and hydrophobic effects, for applications on a glass, is on offer under license agreement

A Czech university with a long tradition in developing various glass coatings is offering a new hydrophobic, olephobic and protective coating for glass. Currently, it won a tough contest carried out by a large manufacturer of glass materials. The university is looking for a company capable to implement their know-how to manufacture the coating for the university partner and also to distribute it further. Know-how provision is assumed on the basis of a license agreement.

Descripción completa

The coating was developed at a Czech university, in department of Glass and Ceramics. The department has a long history of research and development in the area of sol-gel layers especially with the following basis SiO2, TiO2 and Al2O3 for colourful, anti-corrosive, photocatalytic, bactericidal and antireflective applications. Recently the focus of the research has been extended to hybrid inorganic-organic layers.

The product was developed partly in collaboration with a large manufacturer of glass materials who was looking for a coating that would improve their products´ lightfastness and polymer coating peeling and which would have better resistance against adverse weather conditions. Building on a long history of know-how in sol-gel coatings, the university has developed an organosilicon solution that ticked all the boxes, it proved to be better than competing solutions tested and the results were confirmed by independent certification company for glass testing.

The coating shows excellent protective, oleophobic and hydrophobic properties as well as easy application on glass surface without need to use high temperatures or UV for curing and high surface adhesion.

The coating can be applied to glass suited for both interiors and exteriors. The self-cleaning property comes from its hydrophobic and oleophobic surface. The idea is that glass products covered with this coating will generate financial savings due to reduced need to clean such surface and to use cleaning products.

The application of such coating can be useful for example for larger glass constructions where an emphasis on clean glass is high and thus there is a potential for maintenance costs savings. Its protective properties are useful for applications on glass in environments with abrasive weather conditions and for glass products of high value.

This offer is meant for any potential manufacturer that has experience working with teos (tetraethoxysilane) of high purity, there are minimal production costs. The product does not require REACH registration. It is cost-wise solution and it is assumed that the product is comparable to what is already on the market.

The university is looking for companies that would bring the solution to their markets. The companies, manufacturing and distributing chemicals have to be serious about promotion of the solution together with their current portfolio of products. Know-how provision is assumed on the basis of a license agreement.

Socio buscado:

- Specific area of activity of the partner: We are looking for a company that manufactures and distributes chemicals under license agreement. The company ideally works with teos (tetraethoxysilane). From partner is expected production and sales of the coating (mentioned partner in Summary will become the partner´s client).

Advantages & innovations:

Faster and less frequent cleaning of glass when compared to cleaning untreated surfaces.

Chemical resistance to ageing based on meteorological conditions (humidity, condensation and UV radiation combined)

Low technological requirements for application on glass as the coating is ready-to-apply already after one-step preparation process and with no need of additional heat treatment.

During various model tests the self-cleaning properties showed excellent potential for durability - good chemical resistance and resistance against adverse weather conditions proved by the independent model tests

Determination of frost resistance (visual assessment under microscope ? without signs of damage),

Confirmed excellent film hardness by pencil test results ? best possible results reached in Gouge Hardness 5H and very good result reached in a Scratch Hardness 3H (Norm ASTM D3363-00)

Highly adhesive due to strong chemical link between the coating and the glass surface (International standard ASTM D3359-B ? crosscut tape test ? score 5B ? best possible result)

Development Stage:

Field tested/evaluated - The protective and self-cleaning coating was tested carefully in an university lab on a glass product of one of the Czech glass manufacturers. As required by this manufacturer, the coating was tested by an independent certified laboratory for glass analysis, as well. Both labs confirmed outstanding results of the product.
