CHARACTERISTIC PROPERTIES   MARTUT VA 321 is a water - based, Vinyl Acetate -Acrylic Acid Ester Copolymer Emulsion. It is produced by Emulsion Polymerization technique.   TYPE OF POLYMER : Vinyl Acetate-Acrylic Acid Ester Copolymer. SOLID CONTENT (%) : 50 ± 1 PH (at 25°c) : 4 - 5.5 VISCOSITY (at 25°c) (Brookfield RVT)  : 4000 - 10000 Cps (Sp.6/10 rpm) MECHANICAL STABILITY : Positive STABILIZING AGENT : Anionic - Nonionic. PARTICLE SIZE : 0,5 - 1,0 micron DENSITY (at 25°c) : 1,03 - 1,1 gr/ml. MINIMUM FILM FORMING TEMPERATURE : Approximately + 10 ° c. FILM APPEARANCE (at 25°c)  : Clear, flexible, bright.   APPLICATION   MARTUT VA 321 is successfully used as a binder for producing Interior - Exterior Emulsion Paints, Special Decorative Coatings, water - based primers and lacquers. In order to produce Emulsion Paint, a lot of different type Vinyl - Acrylic Copolymer binder can be used. If MARTUT VA 321 is compared with the other Vinyl - Acrylic type binders, a lot of performance advantages are seen, such as, good mechanical and chemical stability, small particle size, good binding power, abrasion resistance and good water resistance.   STORING   (MARTUT VA 321) is a water - based and corrosive material therefore, it should be kept in stainless steel, polyester containers or iron drums, plastic barrels with polyethylene innerlinings. It must be protected from freezing and direct sunlight. It is sensitive to temperatures below +5°c and above +35°c. It can be stored about six month under the recommended conditions.
