ELASTOSIL® M 4541 is a high-performance moldmaking compound, which is particularly suitable for the reproduction of models with extensive undercuts.

 

ELASTOSIL® M 4541 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 4541 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.


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".


Comprehensive instructions are given in our leaflet “ROOM TEMPERATURE VULCANIZING (RTV) SILICONES” – Material and Processing Guideline

Detailed information on other mold-making compounds in the ELASTOSIL ® M range is contained in our brochure „ELASTOSIL® Silicone Rubber for Mold Making“.
