Roymal's UV (ultraviolet) curable coatings are formulated to perform as primers and topcoats. This aqueous UV cure chemistry is based upon acrylic and polyurethane backbone polymers. Aqueous (water based) UV cure coatings are oven dried (water removal is required) and UV cured inline or offline depending on the press configuration. Our UV cure primers allow a print receptive surface (uncured) and remains UV curable after the ink is applied which can potentially form covalent bonds between the ink (if UV active) and the primer after a UV curing cycle. Our UV cure topcoats have excellent water and chemical resistance and have excellent adhesion to films. Typically, these UV cure coatings are applied to paper, paperboard and film using direct/reverse rotogravure or meyer rod.

Packaging engineers, print designers and graphics art professionals are constantly creating new applications that push the limits of aqueous coating technology.  These higher performance applications require aqueous coatings that will perform under the most severe conditions.  Roymal offers a wide variety of aqueous UV curable coatings that are formulated to perform as primers and topcoats, our coatings offer excellent adhesion to films, are heat and chemical resistant and can be applied to paper, paperboard, foil and film products.

Application of Aqueous Ultraviolet (UV) Coatings

Commercial printers frequently send their jobs through using an inline UV curing equipment or an offline, “stand alone” UV curing unit. Aqueous (waterbased) UV cure coatings require the use of a thermal oven to remove the volatiles before the UV curing step.  The UV curing step can also be accomplished in an offline UV cure unit as the aqueous UV coatings have non-blocking properties and can be rolled in reel form prior to UV cure.  Aqueous UV primers and topcoats can be applied via rotogravure and meyer rod.

Roymal Inc. has formulated a select number of aqueous UV coatings that allow printers to take advantage of this unique technology for their variety of end applications, including ink receptive primers (can covalently cure with UV inks) and topcoats.

Custom waterbased coatings by Roymal, Inc. can be designed and manufactured to suit a variety of UV Cure applications.
