Ultraviolet (UV) curing PE tube coating

OP coat

Since our company developed an ultraviolet curing material through our original high polymer technologies, Hayatone UV Series has been used for a variety of applications specialized for customer needs, one component type UV curing ink with a high degree of adhesion to PET bottles, and as a coating material for PE tubes.

Ultraviolet (UV) curing PE tube coating
Hayatone OP Coat Series – ER, ERK, HER

■ Features
  • Both gloss and matte types are available.
  • The gloss type is very shiny and has excellent slip characteristics.
  • Has excellent foil stamping properties (Hot Stamping).
  • Hybrid polymerized type * ・The cation polymerized type curing films have almost no odor. (ERK, HER)
  • Hybrid polymerized types can be used with all ink types. (HER) (Both radical polymerized type and cation polymerized type can be used together. *according to in-house testing)
  • Cation polymerized type curing film produces very little extract and so it can be used for medicine tubes, etc.
  • Product has also been used in numerous products by overseas users. *Hybrid polymerization types (radial/cation polymerization) are patent pending.
