USER’S GUIDE

C-Silicone for masks

Zetalabor,
simplify your work

Designed for the dental laboratory, the Zetalabor C-Silicone
is characterised by high hardness and good mechanical
properties.

It can be used in various applications requiring
short times and not excessively high working
temperatures.

Zetalabor is recommended for counter-moulds
in removable prosthesis applications, masks
for creating artificial gums using the indirect
technique, moulds for pouring self-curing resins
and numerous other applications.

For more than 35 years, its ease of use has helped
speed up laboratory procedures and improve the
everyday performance of dental lab technicians.

MIXING TECHNIQUE

Take one or more measures of Zetalabor
(note: the measuring spoon must be filled
flush with the surface)

For each measure, spread two strips of
Zhermack Indurent Gel catalyst the same length
as the measure, i.e. about 4 cm

Spread Zetalabor on the palm of your hand
and impress the rim of the measuring spoon
onto the material as many times as
the measures used

21

Fold the material onto itself

Mix together using your fingertips
(to avoid heating the material),
forming small S shapes

43

Mix until the material is
even in colour, without stripes

REMOVABLE COMPLETE DENTURE

WITH COLD-CURING RESIN
FOR POURING TECHNIQUE

The combined use of silicones and pouring resins makes it possible to create high-quality removable
prostheses, saving signicant amounts of time compared to the traditional technique which uses
heat-curing resins.

Materials used:

Master model with wax-up Addition of pouring channels and creation

PROSTHESIS REPARATION
WITH SELF-CURING RESIN

When you need to repair a prosthesis, creating a silicone model makes it possible to save signicant
amounts of time (compared with gypsum) and improved management of the prosthesis undercuts.
