Cement Modifier Styrene Acrylic SR PR620 Supplied from Iran
SR® PR620 is a non-plasticized aqueous dispersion based on acrylic acid ester and styrene, stabilized with surfactants. It is a high-solids, flexible resin with cement compatibility designed to modify hydraulic binders. With a solids content of 56 ± 1%, viscosity of 200 ± 50 mPa·s (Brookfield LVT, Spindle 4, 60 rpm), pH of 8 ± 0.5, particle size of approximately 0.2 μm, MFFT of 0°C, density of approximately 1.03 g/cm³, and Tg of approximately -6°C, it demonstrates water-tightness, impermeability, good adhesion to old surfaces, and improved freeze-thaw resistance of cement mixtures.
The Supply Chain Department at Sahi Rasa Company supplies SR® PR620 for export to Afghanistan, Iraq, the Kurdistan Region, Tajikistan, Uzbekistan, Armenia, Georgia, Turkey, Syria, Oman, Kuwait, Jordan, and Russia.
Flexible Roof Coating Styrene Acrylic SR 765 Order from Iran
SR® 765, approximately 50%, is a plasticizer-free aqueous dispersion based on (meth)acrylic acid esters and styrene, stabilized with surfactants. This high-performance binder is engineered for flexible roof coatings, dispersion silicate systems, flexible sealing coatings, binders for fibrous materials, masonry paints, elastomeric wall coatings, plasters and textured coatings, crack-bridging systems, external wall insulating systems, and silicone resin emulsion paints. With a solids content of 50 ± 1%, viscosity of 3500 ± 1500 mPa·s (Brookfield LVT, Spindle 4, 60 rpm), pH of 8 ± 0.5, particle size of 0.09–0.25 μm, MFFT of 0°C, density of approximately 1.02 g/cm³, Tg of approximately -6°C, and hardness of 5 s, it delivers almost clear, slightly tacky films with good flexibility and water resistance.
