Lumicryl U-721S

 U-721S is a UV/EB-curable acrylic macromer suitable for formulating coatings and inks for application on film, laminate, plastic, metal, wood, paper or other substrates. Cured coatings based on U-721S have excellent abrasion, scratch and chemical resistance, and outstanding mechanical properties (eg adhesion and flexibility). U-721S can be used to formulate clear, pigmented or highly filled systems. Coatings utilizing U-721S may be applied using conventional application equipment such as roller, spray, flexo, gravure, screen and others. Formulations based on U-721S dry to a tack-free, dry-to-touch, film after the solvent is flashed off. The dried, but uncured, coating remains in a thermoplastic state and can undergo intermediate processing such as stamping, forming, transfer laminating, thermal transfer, sanding, and re-coating prior to UV curing. The addition of common photoinitiators during the formulating stage is generally sufficient to afford rapid cure of the coating after solvent removal.
