ELASTOSIL® RT 629 A/B的特殊性能
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.
The platinum catalyst is in component B.
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.
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.
