Product Description

Product Description

Photocurable polyurethane acrylate 7317: the "magician" of UV ink special effects. In the creative world of UV ink, polyurethane acrylate 7317 has become the "invisible engine" for creating artistic effects such as wrinkles and snowflakes with its three key advantages of fast reaction speed, good flexibility and fast flower speed. It allows industrial production and artistic design to be seamlessly connected, giving the material a variety of visual charms.

Fast Reaction Speed
Under the trigger of ultraviolet light, its molecular chain can complete cross-linking and curing at the millisecond level, greatly shortening the process cycle. This feature allows the ink to be instantly fixed during high-speed printing, avoiding texture diffusion and distortion, and is particularly suitable for continuous roll production, with an efficiency increase of more than 50% compared to traditional processes.
Good Flexibility
The cured coating has rubber-like flexibility and can withstand bending and stretching without cracking. When applied to wrinkle effects, it can accurately lock the concave and convex texture, and even on soft packaging materials (such as PET and PVC), it can maintain a three-dimensional texture for a long time, with a delicate touch and no shedding.
Fast Printing Speed
The unique low viscosity and high activity design allows the ink to shrink or expand quickly during curing, and complex patterns such as snowflakes and ice flowers are "instantly formed". With different light intensities and temperatures, the crystallization speed and pattern density can be adjusted to achieve a variety of effects from fine snow dots to rough cracks, meeting the needs of high-end scenes such as luxury packaging and creative greeting cards.

From the laser pattern of cigarette boxes to the embossed texture of gift boxes, polyurethane acrylate redefines the artistic boundaries of UV inks with the advantages of "curing in seconds, soft and hard, and controllable special effects", allowing industrial production lines to also output handmade aesthetic surprises.
