ELASTOSIL® M 4641 A/B

$ELASTOSIL<sup>®</sup> M 4641 A/B

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

 

Main application: Vacuum casting for rapid prototyping especially suitable if crystal-clear casting resins are used.

 

Food contact (FDA/ BfR compliant).


特性

  • Very good flow
  • Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
  • Medium Shore A hardness (approx. 43)
  • Good transparency of the cured rubber
  • High tear strength
  • Outstanding resistance to casting resins, particularly polyurethanes and epoxies, for long service life of the molds
  • Oil-free surfaces for crystal-clear resins
