High UV intensity from the number of cycles of radiation would increase the risk of overcuring
, and consequently of degradation to the cured films.
With multiple parts often being produced in the same moulding cycle, there is the potential risk of undercuring or overcuring
For the compounds that had received anaerobic overcuring
or aging, the change in weight could not be ascertained as specimens remained in the mold during aging, and flash became a complicating factor.
, warping, or bad trimming) can be shown on a pie chart for each shift or other period.
These include the use of N- nitrosamine-blocking agents such as ascorbates and [alpha]-tocopherol, or a lowering of the addition level of nitrite in order to prevent overcuring
with its undesirable consequences.
leads to such problems as low "elongation at break" while undercuring yields a low tear resistance.
