| Résumé : |
Lyophobic dispersions of film forming oligomers and polymers is a large group of heterophase binders, which includes emulsions, plastigels, latexes and various hybrid systems. As for pre-sent paint technology, the interest in oligomer emulsions and plastigels fades, whereas synthetic and artificial latexes and hybrid binders play more and more important roles. This paper, the 3rd of the series, is a brief description of colloid fundamentals of emulsions and latexes. Majority of their technical characteristics and their behavior in technological processes are closely dependent on their colloid stability. Stability of and coagulation in lyophobic polymer dispersions, heavily studied and still quite controversial issues in colloid chemistry, are disclosed here briefly and rather qualitatively, aiming to provide readers with the main colloid concepts, useful in the technology and formulation of resin emulsions, polymer latexes and emulsion paints. |
