SCHOTT BOROFLOAT® for Pyrolytic Ovens

Product catalog summary

Applications
BOROFLOAT® is recommended for use in inner oven doors of pyrolytic ovens and other appliances that require high thermal and chemical resistance. It is also suitable for high-performance color printing and can be coated with low-e layers.

Product Description
SCHOTT BOROFLOAT® is a flat glass known for its high thermal shock resistance, capable of withstanding temperatures up to 450 °C for extended periods. It is ideal for inner glass panels of pyrolytic ovens. A new enamel developed for BOROFLOAT® allows for perfect print designs with several color options, large print surfaces, and excellent mechanical and chemical resistance. The enamel's thermal expansion coefficient is adapted to BOROFLOAT® to enhance firing and print performance.

Benefits

High opacity with a single printing run for dark colors
Excellent scratch resistance
Multiple color options
Large-area printing capability
High chemical resistance, eliminating the need for a protection layer

Impact Resistance
The print area can cover up to 45% of the total surface, meeting the minimum energy value of 1.59 J. Designs with larger print surfaces can be tested upon request.

Technical Properties
Standard colors include Blue, White, Black, and Anthracite, each with specific optical density and gloss levels. Mixed colors are available upon request, with white recommended for icons and logos. The glass is resistant to scratches and chemical attacks, with specific parameters affecting impact resistance.
