Unsaturated acrylic oligomers are made from unsaturated acrylic monomers. For example, an epoxy acrylate may be made by reaction of acrylic acid with epoxy resin. [Pg.635]

Oligomers and Resins. Oligomers and resins used were Ebecryl 3700 epoxy acrylate, Radcure Specialties, Inc., Smyrna, GA 30080 Unicarb, which is 73% UVR 6128 (a cycloaliphatic epoxy), 26.5% polyol and 0.5% Silwet L-7602 (See under miscellaneous compounds), Union Carbide Chemicals and Plastics Co., Inc., Danbury, CT 06817-0001 and Heloxy 505 Modifier, Shell Chemical Co., Houston, TX 77210. [Pg.220]

Epoxy acrylates. The most widely used oligomers are aromatic and aliphatic epoxy acrylates. Epoxy acrylates are highly reactive and produce hard and chemically resistant films. The polymerization of monoacrylates produces linear polymers,... [Pg.72]

Epoxy acrylates are also commonly used as oligomers in radiation-curing coatings and adhesives. However, their name often leads to confusion. In most cases, these epoxy acrylates have no free epoxy groups left but react through their unsaturation. These resins are formulated with photoinitiators to cure via uv or electron beam (EB) radiation. The reaction mechanism is generally initiated by free radicals or by cations in a cationic photoinitiated system. The uv/EB cured epoxy formulations are discussed in Chap. 14. [Pg.84]

Epoxy acrylate oligomers that are used in uv/EB curing are very low-viscosity systems with high vapor pressures. Within this group of oligomers, there are several major subclassifications aromatic difunctional epoxy acrylates, acrylated oil epoxy acrylate, novolac epoxy acrylate, aliphatic epoxy acrylate, and miscellaneous epoxy acrylates. Characteristics of these various classes are summarized in Table 4.8. [Pg.84]

Epoxy acrylates are dominant oligomers in the radiation curable adhesives market. A bisphenol A epoxy resin is reacted with acrylic acid or methacrylate acid to provide unsaturated terminal reactive groups. The acrylic acid-epoxy reaction to make bisphenol A diacrylate destroys any free ingredients such as epichlorohydrin used to make the DGEBA epoxy starting raw material. [Pg.261]

Ariga (45) disclosed developments with CTBN-modified epoxy acrylates which when prepared with other lower molecular weight dicarboxylic acids and select carboxyl-terminated oligopolyesters serve as novel oligomers for photocurable coatings. These systems have low uncured viscosity. In the cured state they possess excellent scratch and crosshatch adhesion, good direct and reverse impacts (duPont impact tester) and pass bending diameters of 2 mm. [Pg.10]

Properties of Dual Cured Films. The properties of dual cured films containing the oleamide modified AH and epoxy acrylate were compared. The formulations used oligomers at 65% in TPGOA and included 3% Darocur 1173 and 3% PTSA. They were applied to clay coated board over black lithographic ink with a 3 rod and cured by a UV exposure of 250 mj/cm followed by a thermal cure of 5 minutes at 150 C. The... [Pg.189]

Acrylated oligomers can be divided into three main classes polyester acrylates, epoxy acrylates, and urethane acrylates. Urethane acrylates are an especially important commercial class of oligomers. Applications Include binders for magnetic media, vehicles for inks, and coatings for vinyl floor tiles, optical fibers, and paper. Each application has certain performance requirements that must be met by the urethane oligomer. This paper will discuss the effect of urethane acrylate composition on end properties. [Pg.272]

Figure 11.3. By choosing a suitable monomer, the degree of branching, and molecular weight of the polyester, one can customize the properties of the resulted polyester acrylate oligomers, such as flexibility (Tg), viscosity, functionality, reactivity, and other end properties of the final coatings. The performance properties of polyester acrylates lie between those of epoxy acrylates and urethane acrylates (Table 11.2). Figure 11.3. By choosing a suitable monomer, the degree of branching, and molecular weight of the polyester, one can customize the properties of the resulted polyester acrylate oligomers, such as flexibility (Tg), viscosity, functionality, reactivity, and other end properties of the final coatings.

Wood panel was coated with radiation curable materials and then irradiated using EBM. Radiation curable material is a liquid materials which contains mainly a solution of oligomers in polyfunctional monomer and a small amount o1 additive i.e pigment. Polymerization will takes place under E9 radiation forming a hard ccating of solid polymer. Example of radiation curable material is solution of epoxy acrylate in tripropylen glycol diacrylate. [Pg.614]
