Low-profile additives are generally materials such as poly (vinyl acetate), polystyrene, polyethylene or polycarbonate. During the unsaturated polyester cure cycle, the low-profile additives separate into a second phase, which expand to counteract the shrinkage of the curing unsaturated polyester resin. Material development and the science of low-profile additives have helped create substantial markets for unsaturated polyesters. Their use in automotive markets, where Class A show room quality surfaces is a requirement, is an example of this. [Pg.707]

Studies of rheokinetics over the whole range of polyester curing is based (as for other materials) on a dynamic method, i.e., on measurements of the time dependence of the dynamic modulus at a fixed frequency, from which the time dependence of the degree of conversion (3(t). The observed dependence P(t) for polyester resins can be analyzed by an equation of the type used for other materials. Thus the following general equation was proposed for the kinetics of curing polyester and epoxy resins 69 72... [Pg.48]

Acids and Carboxy-Functional Polyesters. Curing of epoxy resins with acids and carboxy-functional polyesters requires heat. Industrially, these systems are most important in the formulation of powder coatings more than 70% of powder coatings are based on epoxy resins and carboxy-functional polyesters (see also Sections 3.4.2 and 3.4.3).

Impetus (52) for study of IPNs of epoxy and unsaturated polyester results from the lower cost and good performance possible when unsaturated polyester is mixed with epoxy resin. Since polyesters cure by a free radical mechanism, and epoxies cure by cationic initiation followed by condensation, it would appear to be possible to cure the polyester and the epoxy independently of one another. However, this does not seem to be the case. When concentrations are chosen so that the IPN has equal parts of each component, there is an unusually rapid... [Pg.546]
