Elastosil RT 620 A/B is an RTV-2
silicone rubber well suited to Pad Printing
applications. It's a pourable, addition-curing, very
low durometer silicone that can be vulcanized at room
temperature, or at elevated temperatures to increase the
rate of cure. Hardness can be reduced even further by
adding Wacker AK 35 silicone fluid. It has high
reactivity for fast demolding even when large amounts of
silicone fluid have been added.
Features
- cures to a nominal 17 duro Shore A hardness
- high tear resistance
- translucent when cured
- fast non-shrink cure at room temperature
- exhibits excellent flow
