Molding information
OPTOLINQ BMC-4200 differs from other molding compounds and has some special procedures required.
Temperature recovery
OPTOLINQ BMC-4200 must first be allowed to achieve room temperature (20±5°C , 40±15% RH) for atleast 24 hours (Big size) and 12 hours (Small size), without opening the bag before using it, to avoid contamination.
Preheat
Preheating of OPTOLINQ BMC-4200 can be done by using standard RF equipment. The preheating should be done slowly to achieve uniform temperature.
