Abstract

The dependence of the absolute solution viscosity on the concentration by weight shows that the viscosity contribution 1[?], which is to be ascribed to oligomer/solvent interactions, is not the sole deciding factor in selecting solvents in practice. This is shown in Figure 6.

Abstract

Saturated polyesters or so‐called oil‐free alkyd resins have gained increasing importance in recent years for the manufacture of solvent‐contain‐ing stoving paints. Coatings of high industrial use value can be produced from these on metallic objects by crosslinking with melamine/formaldehyde resins. The coatings are hard, scratch‐proof, elastic, stain‐resistant,firmly adherent and resistant to weathering — a combination of properties possessed by only a few other binders. These saturated polyesters are linear or branched condensation products of dibasic or polybasic carboxylic acids and polyalcohols, they carry mainly terminal hydroxyl groups and possess mean molecular weights between about 1,500 and 4,000 (1) (2) (3).
