Technical specifications

Resistance

Coated glasses during a sol-gel process distinguish themselves by high stability and practical value. Corresponding to that they can be processed with many usual methods of glass-processing. The following instructions are to be taken into account.

Basically to be considered: As the thickness of the applied layers or packages of layers is very low (0,05 µm up to 1 µm), basically a negative effect or even destruction by mechanical powers is possible. Therefore during every processing the highest attention must be paid to cleanliness. The effect of abrasive agents like grinding dust, splinters of glass, or sharp-edged parts of metal on the coated surfaces must by all means be avoided.

Chimical properties

Solubility, resistant to water, weak leaches and acids, alcohol and alcoholic solvents, glass cleaner

Temperature stability depends on the substrate
Borofloat 60° to 450°C
Glass ceramic 60° to 650°C

When frequently used at temperatures higher than 550ºC, some filter models can get clouding of layer.

Non-abrasiveness according to MIL-C 48497, moderate conditions, only modest stability against abrasive agents, e.g. bathroom cleaner with polish.

Adhesive stability according to MIL-C 48497 (scotch tape test)

Damp-proof according to MIL-C 48497, 50ºC, 95 % rel. dampness, 24 hours

Coating defects

According to DIN 3140, part 10 50/10 x 1,0 referring to a surface of 100 x 100 mm

flaws < 0,25 mm are ignored
