GC Initial™ LF is a low-fusing ceramic specifically adapted for ceramic-metal alloys within a CTE range of 13.8 to 14.9 x 10-6K-1 (25°-500°C), NPA, high and reduced content gold alloys, as well as galvano or palladium-based alloys (with a silver content < 20%). It is also ideal for correcting restorations made with GC Initial™ MC or as a buildup material on GC Initial™ PC copings.
- Synthetic ceramic with a firing temperature of 770°C
- Excellent, low-shrinkage properties
- Reduced number of hard leucite crystals
- Very stable, even after repeated firings
- Superb polishability
- Superior esthetics for both metal-ceramic and full-ceramic restorations
- Exactly cross-matched coefficient of thermal expansion
