Matches these environments
Why phenolics are chosen
Phenolic resins cure under heat into a dense, highly cross-linked film. That structure resists acids, solvents and many process chemicals, which is why baked phenolics appear in specifications for chemical plants and other aggressive industrial sites.
What the process demands
The film is built up in coats and baked at controlled temperature, which needs a dip line and an oven large enough for the coil. The bake rules out complete units with electrical parts, and the process is not suited to field repair.
Limits
Phenolic films are hard and less flexible than polyurethanes, and they can discolour and degrade under long UV exposure. Film thickness also needs control on dense fins, as with any thicker system.
Do you apply phenolic coatings?
Not as a PG system. If a project specifies a phenolic coating, it is reviewed as a customer-specified coating — cure conditions, oven size and application method decide whether the partner lines can apply it.
What is the closest PG system?
PG-C, an air-dry two-component chemical-resistant system, used where a thick chemical-resistant film is needed and the part cannot be baked.
