ELASTOSIL® M 4511

$ELASTOSIL<sup>®</sup> M 4511

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

 

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



特性

  • very good flowability and self-deaeration
  • very low Shore A hardness (approx. 12)
  • high tear strength
  • extremely high elongation and flexibility
  • outstanding chemical resistance to attack by polyester and polyurethane resins, mold life is significantly extended

ELASTOSIL® M 4511 is a high-performance moldmaking compound, which is particularly suitable for the reproduction of models with extensive undercuts. ELASTOSIL® M 4511 is especially suitable for the processing of polyester and polyurethane resins.


Due to its very high extensibility and low flexural modulus, ELASTOSIL® M 4511 is best suited for the reproduction of fine or fragile models, where the piece may be damaged by more rigid molding materials on demolding.


ELASTOSIL® M 4511 exhibits low hardness and high strength, plus excellent ink transfer characteristics. These make it a perfect base material for the production of printing pads.

If molds for processing epoxy or polyurethane resins are to be made, ELASTOSIL M 4511 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.


Pot lifes and curing times of both catalysts may be accelerated, and thus adjusted to suit the individual application by blending with Catalyst T 47.
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 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
