Hybrid glass coatings have many possible uses. Among them are:

• Protective coatings for specialty optical fiber.
• Low refractive index coatings for anti-reflective applications.
• Colored HG coatings for functional and decorative applications.

Product Characteristics

Cure:

HGT hybrid glass coatings are either heat or UV curable compounds:

• Heat curable hybrids harden (cure) when exposed to temperatures of 50-150 °C for 1-4 hours.
• UV–curable materials harden upon UV exposure from commercial UV lamps.

Inorganic Base:

All HGT products are based on one or more of the following oxide components.

• Silica and silicates.
• Aluminosilicates.
• Titanium silicates.

Coating Thickness.

All UV curable formulations can be applied as single or dual coats with a thickness of 3 to 50 microns where the fiber draw process online is concerned. Heat curable materials may be applied as thin, 1-micron films or thicker, 15-micron coats. For optical fiber drawing a thickness not exceeding 15 microns is recommended.
