Bismuth Free

Zirconia is used as a radiographic agent for various biological cases, such as in dental materials and joint prosthesis.Zirconia is a chemically stable substance so change of color is unlikely to happen.

Easy to Mix with a Small Amount of Water

The bearing effect of the spherical silica particles improves the product’s fluidity. This enables you to make an even paste easily with a small amount of water in a short time.

High Compressive Strength

Since it sets quickly, the product achieves high compressive strength (about 90 MPa) from one day after application. The compressive strength reaches about 140 MPa after a week, matching the compressive strength of glass ionomer cement.

Quick Setting

Since it can be mixed with a small amount of water, the product sets quickly so that initial setting is completed in 15 to 30 minutes. Also, it sets sufficiently without any need to replenish the moisture with a moistened cotton pellet after application. If the paste gets dry and difficult to handle, the viscosity of the paste can be adjusted by adding moisture.

Moisture Ratio (Powder : Water)	State of Paste	Handling Tine	nitial Setting Time
20% (0.2g : 0.05g)	Hard	About 3 min.	15-30 min.
25% (0.2g : 0.07g)	Soft	About 6 min.	30-40 min.
30% (0.2g : 0.09g)	Very Soft	About 9 min.	40-60 min.
Note: As indicated in the above chart, the initial setting time will be longer if the paste is softer. Remove excess moisture with a dry cotton pellet etc. after application.
