Phosphate-bonded, graphite-free speed investment for the complete spectrum of the crown and bridge technique. Speed investment.
Moulds made with Feguravest® S can be placed into the furnace preheated to the end temperature after a setting time of only approx. 20 minutes. The casting is already obtained after approx. 60 minutes. Holding times of conventional investments do not have to be adhered to!
As a result of the fine-grain composition of Feguravest® S, very smooth and precise castings are achieved. Feguravest® S mixed with a special liquid - Feguravest® S Liquid - and can be diluted with demineralized water in any ratio. Thus the total expansion can be precisely adapted to the alloy used.
A special liquid is available for achieving higher expansion with non-precious metal alloys.
