| UV/EB ACRYLATE RESINS | ||
 |
||
| These products, bearing one or several acrylate groups, are derived from chemical backbones such as polyol, polyester, polyurethane,
polyether, epoxies and acrylics. These unsaturated acrylate functionalities have the unique property of instantaneously polymerizing
under ultra-violet radiation (UV) when mixed with an adequate photoinitiator or when treated with a beam of high energy electrons
(electron beam, EB).
The so called UV/EB curable resins are mainly used as solventless binders in inks, varnishes, adhesives and decorative and protective coatings and paints. They can be applied on almost any substrate - paper, wood, plastics, glass and metal. UV/EB curable resins are suppliedas 100 % active materials offering several advantages. The major ecological benefit is that only reactive products are used: this means that there is no solvent recovery step involved and no VOC emission during processing. Energy consumption is low. Curing is performed at room temperature, so heat-sensitive substrates can be used. A significant advantage is the economic benefit. Curing is done at high speed, manipulations and installation are easy, and only minimal floor space is needed. A further advantage is that the finished products are of high quality. The UV/EB curable coating offers higher chemical resistance, better abrasion and scratch resistance, better weatherability and high gloss. These UV/EB curable resins therefore find application in inks and over-print varnishes in graphic arts (magazine covers, cosmetic packaging, lottery tickets and even banknotes); in hard coatings on plastics (automotive headlamps, mobile phone housings, PVC-flooring) and wood (parquet flooring, furniture, doors); in protective coatings used on CD's and DVD's and optical fibres; in solder and etch resistant coatings for printed circuit boards; and in many other uses. |
