UV coating industry
Application of UV in coating industry
Priest UV curing systems are widely used in the film coating industry because they offer higher productivity, good functional properties, and the ability to cure coatings on heat sensitive substrates.
Uses for UV curing range from hard coatings on film products and decorative foils to laminating adhesives and silicone coatings on paper, film and foil for a variety of intermediate and end-use products.
Priest UV curing systems provide high output, long life and consistent output, across the network and over time, which is essential to ensure high productivity as well as less waste and downtime for these high speed production lines.
Application of Infrared Rays in Coating Industry
Web materials such as foil, plastic film, paper or nonwovens often require heat to dry the coating, lamination or embossing.
The doors, center console and instrument panel are made from foil-clad plastic carrier parts. This is usually done by vacuum lamination, a process in which an adhesive is applied to the foil or carrier part. Compared to conventional fused silica emitters, Priest infrared heating systems heat foils faster, reducing cycle times while saving energy.
Advantages of UV curing
Improve productivity
Capable of running heat-sensitive materials
Enhanced functional properties such as scratch and chemical resistance
less waste
greater production flexibility
Requires less energy and footprint
Advantages of Infrared
uniform heating
Fast production speeds possible
Heating of the peripheral area avoids thermal drop at the edge
Fast response time protects the web material from thermal damage in the event of a sudden belt stop
Application
Scratch and chemical resistant topcoats on window films, as well as films and papers for electronic, medical and optical applications
RTA Decorative foils and protective coatings on paper (scratch, stain and moisture resistance) for furniture, picture frame profiles, cabinets and shop fixtures usually made of MDF or particle board
Improve ink absorption of packaging films and papers
Release liner coatings for pressure sensitive labels and tapes, medical bandages and hygiene products
Nanoimprint lithography and other processes for creating patterns on thin films
Curing lamination adhesives (film-to-film, film-to-foil and film-to-paper)
Hydrogels for transdermal and other patches
