$ELASTOSIL<sup>®</sup> M 4514

Pourable, condensation-curing, two-component silicone rubber that vulcanizes at room temperature.


Main application: Making cost effective molds, especially for casting PE and PU resins.


  • very good flowability and self-deaeration
  • low Shore A hardness (approx. 25)
  • excellent tear strength
  • high elongation and flexibility
  • outstanding chemical resistance to attack by polyester and polyurethane resins, mold life is significantly extended

ELASTOSIL® M 4514 is a high-performance moldmaking compound, which is particularly suitable for the reproduction of models with extensive undercuts.


ELASTOSIL® M 4514 is especially suitable for the processing of polyester and polyurethane resins.

If molds for processing epoxy or polyurethane resins are to be made,
ELASTOSIL® M 4514 is cured by adding 5 wt % Catalyst T 21.

For molds used to process other reproduction materials such as polyester resins, plaster, concrete, synthetic stone, wax or low-melting alloys, 5 wt % Catalyst T 51 should be used.

The pot life is the period of time at 23 °C / 50 % rel. humidity during which the catalyzed mix to attain a viscosity of 100,000 mPa s and still be just pourable

For faster curing either catalyst may be blended with Catalyst T 47. E.g. at a ratio
of 95 : 5 (T51 : T47) the pot life decreases to about 30 min, and the mold needs only about 4 h to cure.

Further instructions on blending any catalyst with Catalyst T 47 may be found in our data-sheet: "WACKER® T-Series Catalysts".

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.
