Technical Data On Glassy Carbon Processing
Glassy Carbon Impregnation:
- Substrate densification
- Elimination of surface particulate generation
- Improved wear and erosion resistance
- Extended product life
- Excellent substrate preparation for further processing
COAT:
- Available in both matte and high-gloss finishes
- Elimination of surface particulate generation
- Sealed surface porosity
- Substantially decreased permeability
- Excellent release characteristics (high-gloss)
- May be tailored to suit non-graphite substrates
