Parts A and B components of SILBIONE HCRA 4120 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.
|SILBIONE HCRA 4120 A/B MHC may be stored for up to 12 months from its date of manufacturing.||Please consult the Safety Data Sheet of this product.|
