As a result of the fine-grain composition, very smooth and precise castings are achieved. Beiyuan PFM investment is the reliable alternative to obtain high-quality dental casts.Beiyuan PFM investment is mixed with a special liquid - Beiyuan Special Liquid - and can be diluted with demineralized water in any ratio. Thus the total expansion of the investment can be precisely adapted to the alloy used.
*High speed porcelain denture investment
*have fine particle size to give a smooth surface on the casting
*High casting strengh
*Stable expansion coefficient
*withstand high temperatures without decomposing
*Easily manipulated with enough working time
Best use temperature: 21-25u2103
Powder / Liquid ratio:Powder : liquild= 100g:23-25ml
Mixing time : 60 sec in vac
Operate time : about 4-5 minutes
Final setting time: about 40-60 minutes
Expansion rate: The expansion rate of phosphate bonded investment material may be adjusted by altering the ratio of expansion liquid to water, we can therefore state that:
- Pure liquid gives the maximum setting expansion, meaning the largest casting.
- Diluting the liquid with water will result in the reduction of the setting expansion resulting in
Package Details: 12 powder + 3L special liquid/carton
