Chemical Nature: Sulphonated naphthalene formal dehyde polymer Appearance : Brown Colour Liquid pH (10% soln.) : 6.0-7.0 POPSUPLAST SNF is suitable in structural as well as under water concrete mixes for beams,slabs,columns,etc. POPSUPLAST SNF enables the concrete to flow through dense reinforcement. POPSUPLAST SNF increases work ability of mixes and produces cohesive mixes.It reduces permeability of concrete and increases durability of concrete.It increases slump retention for longer transit period. Consumption & Coverage : Dosed between 1.0-3.0% by weight of cement.
