Foam-plastic coating metals - bonded or releasable coatings

Thermoplastic or thermosetting resin powder is dry-mixed with foaming agent, deposited electrostatically on to the surface, and finally heat-foamed. Cross-linking agents can be added to the resins beforehand. Thermoplastic resins are best used after adding 10% dry epoxide resin. When the coating is...

Beschreibung
Zusammenfassung:	Thermoplastic or thermosetting resin powder is dry-mixed with foaming agent, deposited electrostatically on to the surface, and finally heat-foamed. Cross-linking agents can be added to the resins beforehand. Thermoplastic resins are best used after adding 10% dry epoxide resin. When the coating is to be subsequently released, the substrate is covered with e.g. silicon wax before applying the coating.
