Specific features of ELASTOSIL® M 4503
- Condensation-curing
- Flowable
- Two-component
Data sheets
Due to its good mechanical properties of the cured material as well as its high resistance to polyester resins, ELASTOSIL® M 4503 is particularly suitable as a mold-making material for reproducing models with very pronounced undercuts in polyester resins.
Other materials, such as plaster or wax, may also be cast without any problems from molds made of ELASTOSIL® M 4503.
ELASTOSIL® M 4503 is cured by adding 2 wt % Catalyst T 40. Pot life and curing time may be accelerated, and thus adjusted to suit the individual application by adding up to 4 wt % Catalyst T 40.
Further instructions for preparation and use are given in our brochure “Room Temperature Vulcanizing (RTV) Silicones
- Material and Processing Guidelines”.
Detailed information on other mold-making compounds in the ELASTOSIL ® M range is contained in our brochure “ELASTOSIL® M. Silicone Rubber for Mold Making”.
Storage
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label 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.
