Processing

  • ELASTOSIL R 573/70 A/B is delivered as A- & B-component system. ELASTOSIL® R 573/70 A/B are homogeneously mixed in a ration of 1 : 1.
  • Care must be taken to keep the compound cool during mixing. Crosslinking begins when mixing both components together.
  • The rate and degree of crosslinking depends on the storage time and temperature. At 23 °C the mixture has a pot life of about 24 h. This can be extended by storing the catalyzed mixture at a lower temperature.
  • A homogeneous mixture is a must, but please avoid temperatures >30 °C along the mixing process in order to maintain best processing behavior.
