Orgasol® powder in can coating
Can coating market is divided into food, beverage, aerosol, closures and general segments. But for all these segments, coating requirements in terms of additive properties are quite similar, namely flexibility, high abrasion and scratch resistance as well as high gloss.
Orgasol® powder: an additive that combines flexibility and abrasion/scratch resistance to improve durability
Flexibility is the most critical property especially for internal coating, since cans are formed after the coating has been applied. Orgasol® powder, a thermoplastic additive, when added in a thermoset system, acts as a toughening agent, increasing the flexibility of the coating and its resistance to crack propagation which increases the durability and wear resistance of the interior can coating.
For exterior can coatings, Orgasol® polyamide's dry lubricant effect and its spherical particle shape offer little traction for abrasive materials. This reduces the coefficient of friction of the exterior can coating and enables cans to travel down a production line easier. The spherical shape of the Orgasol® products provide a soft touch haptic coating.
Can coating required a film with a maximum thickness of 12-15 microns. Orgasol® powder grades, 2001 UD NAT 2 (5 microns) and 2002 EXD NAT 1 (10 microns), fit with this requirement and offer uniform particle shape and very narrow particle size distribution.
Orgasol® powder is easily dispersed in epoxy, phenolic, acrylic, polyester formulations. Moreover, Orgasol® powders can be used in water based, powder and 100% solid UV/EB curable formulations, all new trends in the can coating market. In fact, the Orgasol® products provide the same benefits in BPA-free can coating systems.
