Data sheets
ELASTOSIL® M 4443 US is a general purpose moldmaking compound, which is particularly suitable for the reproduction of models with extensive undercuts.
For molds that will process various products including epoxy, plaster, synthetic stone or wax, use Catalyst T 121 Blue US at 10% by wt for a long pot life.
For quick demold times, catalyze with T 127 Red US at
10% by wt.
The pot life is the period of time at 72 °C / 50 % rel. humidity during which the catalyzed mix takes to reach a viscosity of 60,000 cPs and still be easily pourable.
Storage
The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
