Polyrise takes advantage of a recognized expertise in the development and industrialization of both UV and thermally curable hybrid (inorganic-organic) sol gel varnishes.

Polyrise’s sol gels are based upon a proprietary technology and allow for the obtention of nanostructured coatings. They improve or contribute to add new functionalities to several industrial products or consumer goods.

Sol-Gel

1/ Issues

The sol gel process :

• A breaking innovative technology
• It enables to obtain high added value coatings
• soft chemistry based process matching with environmental friendly development issues

2/ Sol-Gel?

The Sol-Gel chemistry allows for the preparation of metal oxide networks(SiO2, ZnO, TiO2…) starting from the hydrolysis and subsequent condensation of organo-metallic precursors.

•  Liquid varnishes (colloidal or oxo-metallic polymer solutions)
• Coatings obtained at room temperature and atmospheric pressure from a wet chemical coating process
• Polyrise’s Sol Gels : hybrid (inorganic/organic) compositions, nanostructured coatings combining

3/ Advantages

• REACH compliant varnishes : hydro-alcoholic solvents.
• Low temperature curing adapted to various types of substrates (PC, PMMA, PET…)
• Compatible with currently existing wet chemical coating lines for niche or volume applications.

4/ Polyrise’s expertise

• The integration and dispersion of nanomaterials into liquid varnishes
• UV and thermally curable sol gel varnishes   - thin film coatings having a refractive index ranging from 1,3 and 1,9
• Layer thickness : 50 nm to 50 µm
• Optical, mecanical and surface properties
• Scale up and production of varnishes : 100 mL to 50 L
