ELASTOSIL® RT 402

$ELASTOSIL<sup>®</sup> RT 402

ELASTOSIL® RT 402 is a pourable, condensation-curing, two-component silicone rubber that vulcanizes at room temperature.

 

Main application: Making pads for pad printing, antistatic behaviour.


特性

  • Very good flowability and self-deaeration
  • Very low hardness (Shore A approx. 11)
  • Good tear strength
  • Excellent transfer characteristics for printing inks
  • Antistatic finish

ELASTOSIL® RT 402的特殊性能

  • 双组分
  • 抗静电
  • 易流动的
  • 缩合固化

ELASTOSIL® RT 402 has been particularly designed as a base material for making printing pads.


A special feature of ELASTOSIL® RT 402 is that it contains an antistatic additive for fast dissipation of static charge that has built up on the pad surface. This feature is particularly important for printing on highly sensitive electronic parts such as CPUs.

ELASTOSIL® RT 402 is exclusively processed with 3 wt % Catalyst T 12, based on the total amount of the mass (rubber base or base plus silicone fluid).


To ensure homogeneity of the material, the components must be stirred thoroughly before they are removed from or processed in their containers, in order to uniformly disperse any fillers that might have settled during storage. It is advisable to thoroughly mix rubber base and fluid before the catalyst is incorporated.


When diluting ELASTOSIL® RT 402 with silicone fluid, it is advisable to thoroughly mix rubber base and fluid before the catalyst is incorporated.


Comprehensive instructions are given in our leaflet "ELASTOSIL® - PROCESSING RTV-2 SILICONE RUBBERS".

储存

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.
