UV curing: Here, “UV” is the abbreviation of ultraviolet light. Curing refers to the process of converting a substance from a low molecule to a polymer. UV curing [1] generally refers to the curing conditions or requirements of coatings (paints), inks, adhesives (glue) or other potting sealants that require UV curing, which are different from heating curing and bonding agents (curing agents). Curing, natural curing, etc.

The physical properties of UV curable materials are essentially affected by the drying system used to cure them. The expected performance, whether it is a protective glue, ink, or adhesive, will depend on the parameters, design, and control methods of these lamps. The four key parameters of the UV lamp are: 1. UV irradiance (or density) 2. Spectral distribution (wavelength) 3. Radiation (or UV energy) 4. Infrared radiation. The ink and protective gel will exhibit very different characteristics relative to the maximum radiance or amount of radiation, as well as the different UV spectra. The ability to identify different UV lamp characteristics and match them to the optical properties of the curable material extends the range of UV curing as a fast and efficient production process. The main application areas of uv curing [2] :

Wood coating & mdash; & mdash; wood primer and surface varnish and paint: filler (filling the interior and surface voids of the board); water-based furniture coating.

Plastic coatings — — film coatings and hard coatings: automotive parts, instruments, optical discs, credit cards, window films, and metallized plastic low-profile coatings for automotive headlights and lighting components.

Paper coating —— surface glazing, metallized paper substrate coating for decorative paper, labels, cards and paper.

Floor coating —— vinyl carpet, vinyl silicon, parquet flooring.

Metal coating —— food cans, car and equipment decoration, traffic tunnel wall panels.

Silicon germanium coating (paper/film) —— release liner, label, casting.

Electronic coatings —— conformal coatings, encapsulating compounds, photoresists, soft (hard) disks, optical disks, video tapes, magnetic tapes, optical fibers.

Ink —— lithographic (cardboard boxes, flexible packaging, magazines, publications), screen printing (plastic labels, plastic bottles, foils, paper and cardboard packaging) and printing.

Adhesives — — laminates (paper or film/wood, film, paper, foil, etc.), general bonding (automotive parts, optics), and pressure sensitive adhesives (labels, contact papers/films, etc.).

Crosslinking —— heat shrinkable film, electrical insulation material.
