Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed as general laminating resin
Phenolic resins without foundry designation classify under adhesive preparations.
If contains significant petroleum solvents
High solvent content may reclassify as petroleum distillates rather than chemical binder.
