Application

Araldite® GT 7072 N is designed for use in high performance coatings systems.

Solvent-containing coatings

Araldite® GT 7072 N combined with polyamines, polyamidoamines or their adducts can be used to formulate solvent-containing reactive coatings which can be used at room or elevated temperatures. Coatings of this type are highly suitable for application as adhesive, anti-corrosion or zinc dust primers, top coats or varnishes. The addition of Araldite® GT 7072 to alkyd/amino resin based stoving enamels enhances their quality.

Powder coatings

The addition of Araldite® GT 7072 N to Type 3 or Type 4 resins (Araldite GT 7013 N, GT 7004 N) improves the flow properties of the powder coatings systems.
