Q

Curing agent ratio error

A

The core of curing abnormality is that the rate and degree of the crosslinking reaction deviate from the optimal window. The adjustment idea is the 'three-element method': formulation (precise metering of catalyst/curing agent), temperature (precise control of mold and material temperature), time...
