- Properties and Uses
Phenodur PR 722 is used preferably in combination in with higher molecular epoxide resins for interior protective stoving coatings in sheet-metal packaging containers and for chemically resistant stoving coatings.
Heat-curing phenolic-epoxide resin-combinations for interior and exterior coatings of metal packaging containers employed in the food industry; high adhesion, chemical resistant protective coatings for apparatus, vessels and pipelines.
Can coating
After being stoved, combinations of 20 - 45 % Phenodur PR 722 and 80 - 55 % Beckopox EP 307 or Beckopox EP 309 (solid resin in each case) yield highly flexible, chemically resistant interior coatings with good adhesion for cans, tubes and other packaging containers employed in the food and luxury commodity industries. An additon of acid catalysts, e. g. Additol XK 406 (3 - 6 % relative to the solid resin constituent) increases the reactivity of the lacquers and thus the film hardness.
Chemically resistant protective coatings
In principle Phenodur PR 722 can also be employed as sole binder for highly resistant stoving coatings. Being relatively brittle, however, the stoved films are used only on rigid substrates. Coating of this type are employed for instance as chemically resistant linings for vessels, equipment and pipelines in the chemical industry. Combinations with high molecular weight epoxide resin, in which the phenolic resin is the main constituent have proved successful for acid-resistant films.
- Processing
Glycol ethers, esters, diacetone alcohol and higher ketones are suitable as solvents and diluents. Aromatic hydrocarbons can be used as thinners. The resin can be pigmented with inert pigments and extenders.
Stoving conditions
Depending on the form of use the stoving conditions vary between 30 and 10 minutes at 170 - 210 °C. In mulitple layer coatings, the bottom coatings are not subjects initially to complete curing. The coating system as a whole is completely cured when the final coat is stoved.
