Technical Data Sheet

Intercoat series 460

Thermosetting powder coating

EpoxyZinc-rich primer

Product description

Epoxy paints Intercoat 460 for interior use. Compared to polyester paints, epoxy paints have improved anti-corrosion properties and increased chemical resistance. They are mechanically strong and moisture resistant, with good resistance to solvents, alkalis and lubricants, and good adhesion.

Typical application

This material features good anti-corrosion properties. It is used as a primer for painting metal surfaces pretreated with spray cleaning, when the item to be painted is exposed to a severe corrosion load.

Pretreatments

Before painting, the item should be adequately pretreated in accordance with surface type, final use and required performance. The following table can be used as a starting point for the pretreatment choice. The surface shall be clean, dry and appear with a rough and dull profile.

Substrate	Indoor use
Aluminium	soil removal, chromate, chrome-free
Steel	soil removal, iron phosphate, zinc phosphate, sand-blasting
Zinc-coated steel	acid attack, iron phosphate, chromate

Oxide (rust) cleaning and degreasing shall be carried out when the simplified process is used. The simplified pretreatment does not ensure the necessary protective properties and decreases the service life of the coating. Hot-dip galvanized steel requires additional mechanical processing (incision).

Cure parameters

Temperature and time combinations resulting in the optimal cross-linking of the coating.

Typical curing

200 °C · 10 min
180 °C · 15 min

Please observe cure parameters closely, since mechanical properties will develop before full cross-linking. To obtain optimal stoving conditions, you are recommended to carry out practical trials adapted to the object in question and the stoving oven each time.

Temperature conditions of curing for each powder are listed on the label. Our technical service department will be glad to advise you. The curing schedule can be set by agreement with the consumer.
