ELASTOSIL® RT 629 A/B

$ELASTOSIL<sup>®</sup> RT 629 A/B

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

 

Main application: Making antistatic printing pads.


特性

  • Antistatic finish
  • Very good flow
  • High reactivity for fast demolding even if large amounts of silicone fluid are added
  • Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat
  • Medium hardness (Shore A approx. 31)
  • Excellent mechanical properties

ELASTOSIL® RT 629 A/B的特殊性能

  • 加成固化
  • 双组分
  • 室温下快速固化
  • 抗静电
  • 无化学收缩
  • 易流动的

Base rubber for making printing pads.


A special feature of ELASTOSIL® RT 629 A/B is that it contains an antistatic additive for fast dissipation of static charge that has built up on the pad surface.


The vulcanizate’s high mechanical strength and long term stability of hardness make ELASTOSIL® RT 629 A/B an ideal base material for producing antistatic printing pads with excellent mechanical properties and long service life.

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


Dilution charts: The following tables show the hardness of ELASTOSIL® RT 629 A/B as a function of the added amount of Wacker Silicone Fluid AK 35 for Durometer Types Shore A and Shore 00.

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.
