Data sheets
Due to its good flow characteristics and its low modulus, ELASTOSIL® M 4400 is particularly suitable as a mold-making material for reproducing intricate structures, even if minor undercuts are involved.
The good resistance to casting resins, especially polyester resins, enables large numbers of castings to be taken from one mold. Other materials, such as plaster or wax, may also be cast without any problems from molds made of ELASTOSIL® M 4400.
Due to the low hardness of the cured rubber and its excellent ink transfer performance, ELASTOSIL® M 4400 is also highly suitable as a starting material for the production of printing pads.
ELASTOSIL® M 4400 is cured by adding Catalyst T37 for long pot lives and curing times, or Catalyst T40 for short pot lives and curing times.
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 mPas and still be just pourable
