The coloring of achromatic glass by means of vacuum process or inorganic sol-gel coatings requires complex and expensive plant technology. ORMOCER®s, on the other hand, as hybrid polymer functional materials, are non-toxic and applicable at low temperatures by conventional lacquer techniques.
Possible applications
- Opaque layers: flat glass coating with pigmented ORMOCER®s
- Industrial glass
- Packaging glass
- Glass sheets for furniture and sanitary appliances
- Glass in architecture and the building industry
- Glazing in the automotive sector
The advantages
- Good adhesion to various glass surfaces
- Unlimited color palette
- Easy reproducibility of the colors
- Finishing by conventional wet painting procedures
- Low curing temperatures (< 200 °C)
- Economical even for smaller batches
- Toxicologically safe
- Additional decorative effects possible (color gradients, partial coloration)
The properties
- Properties and processing techniques of the soles and coatings
- Lead solubility of untreated and pretreated lead crystal glass surfaces
Other areas of application
- Color coatings on mineral surfaces
- Color coatings on metal surfaces
