  • Introduction:

    The RO -SJ is the modified type of melamine super plasticizer, therefore it has all the features traditional melamine super plasticizer have like white color, high water - reducing ratio, non - entraining type, low chloride ion content, no corrosion no steel, good adaptability to various cement, early strength and impermeability of concrete being significantly higher after using the RO - SJ, better constructability and water retentivity, steam curing adapting well etc. Through a special dusting drying process, the particle structure of powder has been improved and the liquidity of the powder is better than that of melamine powder, therefore when using this product in powder building materials, the mixed effect is very satisfactory. This product complies with the national standard GB8076 - 2008 of super plasticizer indicators.

  • Specifications:

    Powder: RO - SJ (type I)

  • Applications:
    (1) Impervious insulation mortar, gypsum products, self - leveling floor, joint sealer, grouting materials etc;
    (2) High - strength concrete, high flowing concrete, high durable concrete, aluminate cement refractory concrete, low cement refractory concrete, steam curing concrete etc;
    (3) Especially applicable to the dispersant of dry - mixed powder building materials.
