Sun Chemical Makes Mark with Ink Technology Breakthrough

Published on 2005-09-27. Author : SpecialChem

BRUSSELS, BELGIUM -- A major breakthrough in world-leading UV ink technology, which has dramatically improved efficiency and production speeds, has been announced by Sun Chemical, the world's largest producer of printing inks and pigments.

Sun Chemical has introduced the product SOLARCAT™, which is the most advanced cationic UV flexo ink system of its kind in the world and at least two times faster curing than other products in the marketplace.

It has the outstanding technical properties as a cured ink film recognised in cationic systems, while delivering significantly improvements over existing technologies. These include higher cure speed, lower humidity sensitivity, low press room odour and without the creation of hazardous photoinitiator by-products in the curing process.

The innovative SOLARCAT™ product is part of Sun Chemical's Solaris ink portfolio that has been formally launched in Europe at Labelexpo Europe, in Brussels, from September 21-24, which is the world's largest gathering of labels, product decoration, web printing and converting.

SOLARCAT™ inks, which are now available for commercial supply, are undergoing trials at various industry-leading speciality packaging, label and shrink sleeve companies worldwide. The inks are also being printed live at Labelexpo at the Gidue stand (5B50) onto a PET shrink film supplied by DuPont Teijin Films.

Sun Chemical, which is already at the forefront of new technologies such as digital printing and Radio Frequency Identification (RFID), has brought to market unique developments in UV curing technology that includes these new generation cationic inks and low odour and migration products based on M-Cure technology.

Important attributes for the SOLARCAT™ inks are:

  • Cure speed at least twice as fast as traditional cationic technologies, up to 250 m/m, and less sensitive to humidity
  • Low press room and cured print odour
  • No hazardous photoinitiator bi-products
  • Exceptional adhesion and resistance on almost all filmic and metallised materials used in narrow-web printing
  • High shrink film performance up to 80% and retortable without loss of adhesion
  • High colour strength giving excellent mileage and allowing the use of fine aniloxes for high fidelity printing
  • Low viscosity for ease of handling and excellent printability
  • Based on new and unique technology subject to patent applications by Sun Chemical

Jonathan Sexton, Sun Chemical's European Product Manager, Narrow-Web Labels, said: "The SOLARCAT™ inks display exceptional technical performance combined with ground-breaking productivity and solve many of the drawbacks of existing cationic technologies."

Sun Chemical, which has the ink industry's most extensive network of customer service centres, in the world, is building productivity, innovation, global reach and local service into the Solaris product line. It has also added "total solution" packages to its offering, which include a selection of non-ink printing consumables."

Felipe Mellado, Sun Chemical's European Vice-President, Technology and Marketing, said: "The creation of Solaris signals our commitment to the needs of the growing narrow-web market. With the development of Solarcat, Sun Chemical is demonstrating the commitment to building productivity, innovation, global reach and local service into the Solaris product line."
