Pourable, condensation-curing, two-component silicone rubber that vulcanizes at room temperature. Shore A 30 hardness. Suitable for production of flexible moulds.

 

Special features

- very good flowability and self-deaeration

- medium Shore A hardness (approx. 32)

- excellent tear strength

- high elongation and flexibility

- outstanding chemical resistance to attack by polyester and polyurethane resins, mold life is significantly extended

 

Application

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.

Processing

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 "ELASTOSIL® - PROCESSING RTV-2 SILICONE RUBBERS".

Detailed information on other mold-making compounds in the ELASTOSIL®M range is contained in our brochure "ELASTOSIL ®M. Mold-Making Compounds

For Maximum Precision".

Pot life o 60-90 minutes with both T-51 and T-21 with a curing time (tack free) of 8-10 hours.
