Distinguishing Features

Films based on Phenodur PR 411/75B are almost colorless. The overall properties of Phenodur PR 411 resemble those of Phenodur PR 401, but Phenodur PR 411 displays improved flow properties and a significantly reduced residual monomer content when compared to Phenodur PR 401.

Suggested Uses

Phenodur PR 411 is meant for the coating of interior and exterior surfaces of packaging containers and cans; as high adhesion, chemically resistant protective coatings for apparatus, vessels, pipelines etc.; for heat curing phenolic/epoxide and phenolic/polyester resin combinations; for heat curing phenolic/polyvinylbutyral combinations and for physically drying paints with resistance to fuel and oil.

Processing

Combinations of Phenodur PR 411/75B with epoxide or polyester resins have to be cured for 10 - 20 min at 190 - 210 °C to be fully cured. The mixing ratio between Phenodur PR 411 and the co-curing resin should be between approx. 15 : 85 and 30 : 70 (calculated as solid resins). After curing, these formulations yield high adhesion, chemically resistant films for the internal and external coating of cans, tubes and other packaging containers.

Furthermore, Phenodur PR 411 can be used as a sole binder in high resistant baking enamels. The cured film is comparatively brittle and can only be used on rigid substrates. Polyvinyl butyrals can be applied as plasticizing agents.
