CAVEX CA37 | NORMAL SET | ALGINATE IMPRESION MATERIAL

The basic composition of both CAVEX CA 37 Normal Set and CAVEX CA 37 Fast Set is as
follows:
alginate : app. 14% w
calcium sulphate : app. 10% w
fillers : app. 70% w
retarder, stabilisers, pigment and flavour : app. 6% w
The alginate, a soluble salt of alginic acid (extracted from brown seaweed), serves as the
thickener for water, giving the paste, upon mixing, the correct consistency. It also reacts
chemically with calcium sulphate to make the paste harden into a solid impression.
The fillers give the mixture its mechanical strength and proper handling characteristics.
A retarder, sodium pyrophosphate, is used for achieving the proper hardening-time, the stabilisers
will improve the surface-smoothness of the gypsum-cast and the pigment facilitates the “reading”
of the impression by the dentist for a good judgement of its quality.

CAVEX CA 37 Normal Set and CAVEX CA 37 Fast Set are alginate impression materials for
dental use.
CA 37 Normal Set has a normal setting time for general use, CA 37 Fast Set is quick setting and
therefore particularly suited for orthodontics.
Both are presented in the form of a homogeneous, pink-coloured powder with a nice peppermint
flavour. A special characteristic of both powders is that they are dustfree: the powder is treated in
such a way, that no dust is generated during dosing and mixing. It also facilitates the mixing
process through easy absorption of water by the powder, offering both dentist and dental assistant
convenient and hygienic handling.
After mixing with water, a smooth paste is formed that is loaded into an impression-tray and
placed in the mouth of the patient. After hardening of the paste, due to a chemical reaction, an
accurate impression is obtained, that can be taken out of the mouth without any deformation,
because of its elastic nature.
By pouring the impression with gypsum, or dental stone, a precise model of the situation in the
mouth can be prepared, allowing the dental technician to construct a well-fitting dental prosthesis.
