Dosing
－Stir the powder to
loosen it well

storage box with a light, swift movement and then stroke the powder smooth: do
not compress the powder in the scoop.
－Mix water (at room
temperature) and powder in the mixing cup
* for a partial
impression 1 scoop + 1/3
beaker of water
* for a full
impression 2 scoop + 2/3
beaker of water
* for an
extra-large impression 3 scoop +
3/3 beaker of water
Ideal mixing ratio: 19.3g=2measuring scoops: 46ml=1full
beaker.
You can make the mixture thinner or thicker by adding
more or less water respectively.
Mixing
－Mix both components
together carefully and thoroughly for 30 seconds until a smooth and homogeneous
mixture is obtained.
－Fill the tray
immediately and use a wettened finger to stroke it smooth.
－Make sure that the
patient has rinsed the mouth with warm water in the mean time.
Taking the impression
－within 1 minute after
mixing, insert the filled impression tray into the patient’s mouth applying
gentle pressure.
－Allow the impression
material to set in the mouth for 1minute.
－remove the tray from
the mouth in a single rapid movement.
－Rinse the tray under
cold running water to remove saliva and any residues.
－Remove any excess
water, but leave the surface moist. Never blow-dry!
Making the plaster models
－Immediately after
rinsing, pour out the plaster impression and make a second plaster model if
desired.
－If immediate pouring
is impossible: store the impression in a firmly sealed plastic bag and add a
few drops of water to achieve a relative humidity of 100%. This is essential
for optimum results at a later pouring.

Mixing time: 30″~45″
Total working time: more than 1,30 min
Total setting time: 2′30″~3 ′
Performance
In 2%
glutaraldehyde or 0.5% sodium hypochlorite disinfectant and disinfection 15 -30
minutes, non-obvious phenomenon of fading. It proved that alginate products
have disinfection and antimicrobic capability.
Shelf life:
3years.
Note:
1. The working/setting times increase with a lower
(water) temperature. At higher temperatures the times become shorter.
2. The water hardness has the same effect: the harder the
water used for mixing, the shorter the working/setting time.
3. This instruction suits for all Hygedent brand product.
