TONTEN TM phenolic resins demonstrate exceptional chemical resistance. phenolic resin is yellow, transparent, amorphous bulk material, due to containing free phenol was slightly red, the actual proportion of the average 1.7 or so, soluble in alcohol, insoluble in water, water, weak acid, weak alkaline solution stability. By phenol and formaldehyde in the catalyst conditions polycondensation, by neutralization, washing and made of resin. Depending on the choice of catalyst can be divided into two types of thermosetting and thermoplastic.
