ELASTOSIL® RT K

ELASTOSIL® RT K is a pourable, condensation-curing, two-component silicone rubber that vulcanizes at room temperature.

 

Main applications: 

  • Encapsulation of electrical and electronic components
  • Making flexible molds for reproducing models with no or only minor undercuts in all common reproduction materials
  • Release coat for rigid molds for the casting or foaming of polyurethane resins


Properties

  • Excellent flowability and good self-deaeration
  • Medium Shore A hardness (approx. 45)
  • Good dielectric properties
  • Outstanding resistance to casting resins, particularly polyurethanes

Specific features of ELASTOSIL® RT K

  • Condensation-curing
  • Low viscosity
  • Two-component
  • Encapsulation of electrical and electronic components
  • Making flexible molds for reproducing models with no or only minor undercuts in all common reproduction materials
  • Release coat for rigid molds for the casting or foaming of polyurethane resins

ELASTOSIL® RT K is cured by adding Catalyst T40 or T47
The pot life is the period of time at 23 °C / 50% rel. humidity during which the catalyzed mix to attain a viscosity of 100000 mPa s and still be just pourable.

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.
