Dual‑cure coating is a high‑performance functional coating system designed with two separate curing mechanisms . It is widely adopted in UV offset printing, packaging, electronics protection and industrial coating sectors.
Traditional single UV coatings only crosslink when exposed to ultraviolet light. They often suffer from incomplete curing and sticky surfaces on shadowed areas, deep gaps or thick coating layers. Dual‑cure technology was developed specifically to fix this limitation.
There are two dominant commercial systems:
1. UV + moisture dual‑cure (the most popular)
Surfaces hit by UV or LED light cure in seconds for immediate tack‑free drying, supporting fast production speeds. Areas out of the light reach continue crosslinking slowly by reacting with moisture in the air. This is ideal for 3D shapes, intricate parts and conformal coatings.
2. UV + thermal dual‑cure
UV irradiation quickly sets the coating surface. A subsequent low‑temperature heating step completes deep curing. This variant works well on plastics, metals and wood substrates.
Most dual‑cure products are 100% solids, solvent‑free and low in VOC. Many grades meet strict low‑migration requirements for food packaging. The cured coating offers strong substrate adhesion, good scratch resistance, chemical resistance and stable mechanical properties.
Common applications include paper lamination, flexible packaging, offset UV inks, PCB conformal coatings, automotive decorative coatings and special industrial protective finishes.
Our dual‑cure raw materials and coating formulas are compatible with both LED‑UV and conventional UV production lines, delivering consistent performance on high‑speed coating and printing equipment.
