We offer two different types of Tokuyama
A-1α based on the curing time : Fast Set(which
comes in a blue package) and Normal-Set(which comes in a pink package). They should be selected based on purpose and
patient condition, as well as season and climate.
Curing characteristics for
fast-and normal-sets based on water temperature:
1. Working time, 2. Holding
in oral cavity, 3. Removable
Incorporating potassium alginate and the effects of Plus Alpha !
A-1α is an alginate impression material which
contains 100 percent potassium alginate as the alginate compound. As compared
to other alginate impression materials incorporating sodium alginate, the effects of potassium ions help to produce a stronger adhesion with
agar and produces a much more precise and smoother surface on the stone model.
agar has become much stronger, thus giving an improved precise combination
A-1α adheres to all agars, thus any agar/alginate
combination impression can be performed with confidence.

Easier to mix.
A-1α mixes extremely well with water,
thus allowing it to be quickly and easily mixed into a uniform and fine creamy
A-1α's effects of incorporating
potassium ions force stone to be hardened precisely on its surface, resulting
in the ability to exactly reproduce detailed impressions.
microns) reproduction of the surface of a stone (ISO Type 3) surface, SEM 100
Available for all kinds of
With A-1α there is no fear of surface
dilapidation, and a smooth surface can be attained not only with stone (ISO
Type 3) but also with stone (ISO Type 4).
Elimination of Patient Discomfort
As is the case with our line of alginate impression materials,
A-1α also does not flow into the patients' throat during impression because
of its viscous nature. Along with its fresh mint smell, impressions can be made
with more comfort.
Extremely Precise Impression
A-1α has a very low permanent strain, and only minute dimensional changes
during storage, thus impressions remain precise and unchanged for a long period
A-1α has a high tensile strength and high elasticity, thus impressions
will maintain their original form when you remove them from the undercut and
Advanced Dust-Free Quality
Because of A-1α's advanced dust-free
quality, the working environment remains clean.
