| PROCESSING PROCEDURE |
HMU-90P should be 80-85°C and thoroughly degassed at 1-5m of vacuum until
excessive foaming stops.
The curative should be added to HMU-90P, the MOCA must first be melted at 110-
120°C prior to mixing. After adding the curative, mix thoroughly, being careful not to
introduce air into the mixture.
Pour mixed HMU-90P/MOCA into moulds which have been preheated to 80-100°C and
precoated with release agent.
