WebGenerally speaking, our linings should not be exposed to temperatures that are significantly higher than the recommended Peak Metal Temperature (PMT) that is noted for each lining option. For the our epoxy phenolic linings, the PMT ranges from 350-425F. The dark red epoxy phenolic lining has a PMT of 425F. In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−OH) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, C 6H 5OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. how to delete all junk mail in outlook
