Branched epoxy coatings

Powder coatings of branched epoxy resins were prepared by extruding stoichiometric amounts of the epoxy resin and methylene dianiline (1 equivalent of epoxide per 1 N-H... [Pg.196]

Powder coatings were prepared by extruding stoichiometric quantities of methylene dianiline with epoxy resins varying only in branch concentration. More highly branched resins result in a more tightly cross-linRed thermoset network. [Pg.196]

The use of epoxidized hyperbranched polyesters as toughening additives in carbon-fiber reinforced epoxy composites has been demonstrated (Boogh et al., 1995). Since a hyperbranched resin has a substantially lower viscosity and much shorter drying time than a conventional (less branched) resin of comparable molecular weight, hyperbranched polymers have been used as the base for various coating resins (Pettersen and Sorensen, 1994). [Pg.307]

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.
