ELASTOSIL® M 4635 A/B

$ELASTOSIL<sup>®</sup> M 4635 A/B

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

 

Main application: Making molds for concrete casting.

 

Food contact (FDA/ BfR compliant).



Properties

  •  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.37)
  •  high tear strength
  •  excellent long-term stability of the mechanical properties of the vulcanizate
  •  outstanding resistance to concrete

Specific features of ELASTOSIL® M 4635 A/B

  • Addition Curing
  • BfR compliant
  • Excellent mechanical properties
  • FDA compliant
  • Flowable
  • Food-contact
  • No chemical shrinkage
  • Resistance against casting resins
  • Resistance against concrete
  • Two-component

Due to its outstanding resistance to concrete and superior mechanical properties, ELASTOSIL® M 4635 A/B is perfectly suitable for all molds of models with undercuts that are to be reproduced in casting resins, and a certain inherent rigidity of the molds is required.

As a medium-Shore addition-curing RTV-2 silicone rubber that cures without undergoing demensional shrinkage, ELASTOSIL M 4535 A/B is also extremely suitable for casting other common reproduction materials, especially casting resins where absolutely accurate copies of models are required.

 

Detailed instructions for preparation and use are given in the brochure “Room Temperature Vulcanizing (RTV) Silicones - Material and Processing Guidelines”.

 

Important note:
The platinum catalyst is in component A.


Caution:
A and B components may only be used together if they have the same batch number.

Storage

The 'Best use before end' date of each batch is shown on the product label.

 

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
