Phenolic curing
Phenolic curing
(OP)
How do you know when a phenolic is cured? Part under pressure for 10 min at 385F, cooled to 260F then ejected. When put in oven at 175F overnight, got a potato chip... Why wasn't this cured???
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Phenolic curing
I know only a little about thermosets. I do know one company that adds a colorant into their material so when it is molded it comes our green or some other color. When it is fully cured, it turns black. I do not know the chemistry behind it but perhaps you can look into it with your material supplier.
Good luck.

with hexamethylenetetramine ( and no dye ). It changed the color from light brown to yellow, when done.
