| Résumé : |
Emulsion based paints can be formulated with a variety of chemically different polymer dispersions. These binders are mainly based on acrylic or vinyl ester copolymers. The present publication treats comparative experiments of acrylic copolymers having different minimum film forming temperatures (MFFT). For masonry, as in many applications, the principle question is, which is the right performance profile for a copolymer dispersion based on acrylic and styrene monomers to achieve a long lasting paint? Further, the market is looking for binders which permit the formulation of solvent-free architectural coatings. This requirement can be achieved by using a binder having suitable MFFT. The MFFT of such a binder should be below 5°C. We want to discuss similarities and differences between acrylic/styrene emulsions having different MFFTs. |
