A and B components of SILBIONE HCRA 4170 A/B HC are designed to be mixed in equal parts by
weight or volume using standard rubber processing techniques such as two roll
milling. For optimum results, freshen both parts separately on the two roll
mill before mixing them. Do not allow the material temperature to exceed 30°C
during the milling. The mixed material should be used within two hours to
prevent structuring and premature crosslinking. Molding is typically 10 minutes
at 120°C or 3 minutes at 165°C.
