Dentsply Zelgan 2002 Alginate :450 gms.

Features

Dentsply Zelgan 2002 is a dust-free irreversible hydrocolloid alginate impression material that can be used to make perfect preliminary dental impressions with excellent reproducibility of the anatomical features of the dental arches.

This quality impression material can be used to make dental impressions to fabricate study models, models of the opposing arch and working models for the fabrication of orthodontic appliances, removable prosthesis, and temporary restorations.

The Dentsply Zelgan 2002 dust-free alginate impression material is in compliance with the ISO 1563 and EN 21563.

Special formulation of the powder eliminates dust during mixing.

This aids the clinician to make dental impressions of higher quality. To enhance the adhesion of the impression of the tray, alginate tray adhesive materials may be used.

The impressions made from Zelgan 2002 retain accuracy for a considerable amount of time, provided if placed in a humidor maintaining at least 90% relative humidity. However, it is recommended to pour casts immediately or within 48 hours of making the impression.

Warning – Zelgan 2002 may cause allergic reactions with patients sensitized to spearmint oil or other components of the material. In such cases, the use of Zelgan 2002 is contraindicated.

MIXING INSTRUCTION:

Machine mixing – 8 to 12 seconds (or as per manufacturer’s instructions)

Note: Machine mixing will slightly shorten working and setting times.

Hand mixing – a vigorous figure of 8 motion is employed for the recommended mixing times as specified below

Mixing, Working and Setting Times
Temperature of water used (in centigrade)	Mixing time (in seconds)	Working time (in minutes)	Setting time from start of mix at 35oC (in minutes)
15	30	2’05”	3’00”
23	30	1’30”	2’00”
31	30	0’50”	1’20”

Please note that the above setting times assume the impression material is placed in the oral cavity, 30 seconds from the end of a mix. In practice, variations in time of placements may occur.
