AUROSIL FORM 20 FAST (100g)

Type A silicone molding material for duplicating models made from materials such as: plaster, blocking material (with chemical expansion control), resins, wax, etc.

The high-flow silicone for duplicating models enables exceptional accuracy of reproduced details with a relatively short setting time. Silicone AUROSIL FORM 20 FAST can be used both in the technique of manufacturing skeletal dentures, flexible dentures, creating control models, as well as in other technological processes requiring duplication of a specific element with a defined shape, including modeling resin (e.g. Form Plast).

Silicone Aurosil Form 20 Fast can also be successfully used for creating a negative mold during the manufacturing of dentures using the casting technique (e.g. from Villacryl SP acrylic resin).

Advantages:

– optimally flowable consistency during pouring
– excellent flow into all areas essential for duplication
– reproduction of all details of the duplicated model/element
– relatively short setting time
– effective in all dental (and other) techniques requiring duplication
– minimal linear shrinkage (<0.1%)
– excellent mechanical properties
– no release of toxic substances during and after curing
– easy removal of model/element from the silicone mold
