Additives For Can And Coil Coatings

ADDITIVES FOR CAN AND COIL COATINGS

The property requirements for can and coil coatings are diverse. Chemical resistance and ductility are just two examples. In addition, weather resistance and color stability play a major role. Areas of application include coatings for metal packaging (beer and beverage cans, food cans, crowns, caps, and closures and tubes) as well as coatings applied to flat metal sheets or strips packaged in rolls or coils mainly used for cladding and roofs.

WATERBORNE

A waterborne coating is an environmentally friendly surface treatment that uses water as a solvent to disperse the resin used to make the coating or paint. Water comprises a minimum of 80% of the solvent used. Its aim is to make the coating or paint an easy-to-apply, eco-friendly product. Waterborne coatings are widely used due to their low VOC (volatile organic compounds) content.

SOLVENTBORNE

Solventborne coatings are surface treatments that contain VOCs. Advances in waterborne coatings are making them an increasingly attractive option as a method of protecting material surfaces even in harsh conditions. Solventborne coatings can be differentiated by their VOC content, which can range from medium solids (approx. 50% VOC) up to ultra high solids (less than 10% VOC).

High surface smoothness, very good scratch and abrasion resistance, absence of bubbles, good substrate adhesion and very good leveling are decisive characteristics for can coatings. AEOR offers additives which are suitable for food contact applications according to certain regulations and can be used in solvent-borne, aqueous and radiation-cured can coating systems.
