UV Curing

Ultraviolet curing (commonly known as UV curing) is a photochemical process in which high-intensity ultraviolet light is used to instantly cure or “dry” inks, coatings or adhesives.

Conventional heat- and air-drying works by solvent evaporation. This process shrinks the initial application of coatings by more than 50% and creates environmental pollutants.Using light instead of heat, the UV curing process is based on a photochemical reaction. Liquid monomers and oligomers are mixed with a small percent of photoinitiators, and then exposed to UV energy. In a few seconds, the products - inks, coatings or adhesives instantly harden.

UV Reflectors

HHV has the comprehensive technological solutions for every UV curing applications. It has demonstrated its capabilities from manufacturing spherical, elliptical substrates in its optical manufacturing facility and special coating design to absorb the heat energy.

In Ultra Violet ink curing, no loss of ink thickness, no environmental pollutants and it is a rapid process.

Disadvantages of solvent curing:

  • Solvents make up more than 50% of the ink
  • Slow process
  • Not suitable for the heat sensitive materials

Advantages of UV Curing

  • Inks, coatings, Adhesives with dramatically improved physical properties
  • Faster production speeds and capacity
  • Reduction of work – in process
  • Environmentally friendly-Energy savings
  • Less floor space needed
  • Increase yield and reduce scrap

  •         Glass & Aluminum UV Reflectors

    UV Reflectors

    HHV produces world-class UV reflectors, which can be used in an optical system to dramatically speed up the UV curing process. UV reflectors give a high reflectance of UV energy while visible...
