Parts A and B components of Silbione ® HCRA 4365 HPM are designed to be mixed in equal parts by weight or volume using standard liquid injection molding processing equipment and techniques. Airless mixing, metering and dispensing equipment are recommended for production operations. Accurate measuring and complete mixing are essential factors in obtaining consistent results.
can be achieved in 10 minutes at 120°C or 3 minutes at 165°C. Post curing for one hour at 165°C is recommended to stabilize physical properties.
The mixture of Parts A and B components of Silbione® HCRA 4365 HPM will remain stable for at least 72 hours at 23°C. Working time can be further extended by storing the mixed material in a freezer.
Special care must be taken to assure clean molds and a clean
work area with no organic rubbers used on the same processing equipment. Traces
of foreign materials can poison the catalyst and inhibit the cure. All metering
and mixing equipment should be thoroughly cleaned. Polymer systems, which
contain traces of amines, sulfur, nitrogen oxide, organotin compounds and
carbon monoxide can interfere with the cure of this product and should be
