UV dryers are intended for curing of coatings. UV-curable coatings consist of a blend of reactive monomers or oligomers capable of free-radical-initiated polymerization. Photo initiators are used with UV-curable coatings and they are the source of free radicals produced on irradiation. [Pg.927]

Ultraviolet Photoinitiators. Photoinitiators are used in increasing volume for a multitude of appHcations. The most important of these are in the formulation of uv-curable inks and in the production of coatings on vinyl flooring, wood, and electronics components (28,29). The most common types of photoinitiators are phenone derivatives, for example, acetophenones and hen 7ophen ones (30). [Pg.320]

Esters of methacrylic acid (also called methacrylates) are most commonly used for adhesives. This is slightly different from UV curable coatings, where acrylic esters are generally preferred. These differ by a methyl group as in Scheme 1. [Pg.829]

Coatings. The use of photopolymer materials for the preparation of curable coatings is highly diverse. Many of the products used at home and at work have been coated with a photopolymer material for protective and decorative applications. Just a few of the many applications of photopolymer technology include UV curable pigmented (94) and clear (95-96) protective coatings, protective furniture (97) and... [Pg.10]

Traditionally, UV curable polymers have been utilized as coatings for wood and vinyl floors, but their applications have increased dramatically over the last twenty years to encompass many diverse areas, including optical fiber coatings (7), adhesives (2), disc replications (3-5), and microelectronics (6). This widespread use of UV cross-linked systems is attributed to their rapid, energy efficient curing and their solvent free, one piece formulations. Typically, UV curable systems require only a small fraction of the power normally utilized in thermally cured systems and their solvent free nature offers an environmentally safer alternative. [Pg.150]

Such sol-gel derived and ultraviolet (UV)-curable hybrids afford enhanced corrosion and mechanical protection of fibres compared to standard polymer coatings used by the fibre optics industry. These coatings are hard, transparent and impossible to strip since they become intimately bonded to the fibre surface during curing. [Pg.162]

Many novel coatings technologies are discussed in the review by McGinniss (McGinniss, 1996) who discusses advances made in environmentally benign coatings that include silicon oxides, sihca fillers, and hybrid waterborne/UV-curable systems. [Pg.240]

UV curable coatings are applied to a variety of flat, rigid substrates, such as particle board, medium- and high-density fiberboard, wood veneers, polycarbonate, poly(methylmethacrylate), paper, and metal sheets and foils. An example of a formulation for UV curable coatings is in Table 7.1. [Pg.143]

Silicone release liners are used as a nonadhering surface to which adhesive materials, such as, for example, pressure-sensitive adhesives, can be laminated. UV curable release coatings are based on poly(dimethylsiloxane) oligomers functionalized with acrylate or epoxy groups and are mostly coated onto papers or thin films. [Pg.152]

The fundamental benefit of UV powder coatings is that they can be processed at considerably lower temperatures than traditional thermoset powders. While ordinary thermoset powders require temperatures in the range of 350 to 400°F (177 to 204°C), commercial UV curable powders require temperatures that are not higher than 220 to 250°F (104 to 121°C). A comparison of the two types is in Table 7.7. [Pg.164]

In contrast to the conventional powder coating, the melt and cure processes of UV curable powders are decoupled, so that while heat is used to flow the material, it does not cure the powder, and the cross-linking occurs only after the exposure to UV light. Because the temperature required for melting the... [Pg.164]

Almost any substrate that will be powder coated, whether it is metal, medium-density fiberboard (MDF), or some other material, requires some kind of surface freafmenf. Surface preparafion (prefreafmenf) of wood and more specifically, MDF preparation consist of sanding, removal of confami-nanfs, and board condifioning. MDF boards fhaf will be coafed by UV curable powders should have a moisture content of 49%. If is also a common practice fo preheaf MDF boards prior to application of fhe UV powder. Mefal surfaces are always cleaned by washing and usually freated by a phosphafe primer. Conductive plastics are washed and dried and then coated without any further treatment. Nonconductive plastics are made conductive by applying a primer coat or treated by plasma or flame. ... [Pg.167]
