Detailed Description

  It is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate SNF, PNS and FDN etc.
  
  Na2SO4 has 3 grades:5% 10% 18% for exporting markets,in domestic we also have 3% 23% Na2SO4 content FDN.It contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable.


1. Application Method and Notice
1,Blend dosage range is 0.5-1.2%. Appropriate blend dosage can be selected according to project object and the materials used during application.
2,FDN powder is recommended to be applied in solution. It can be used in dry form, but make sure mix it thoroughly with concrete.
3,If this product is applied with adoption of stagnant water blending method or post-blend approach, water reduction and dispersion will be better.

Features:
1,Main ingredient is β-naphthyl sulfonate formaldehyde condensate, sodium sulfate≤5 and 10 and 18 and 23%. 4 main types.
2,Good dispersion, water reduction and early-strength effect. It can speed up the turnover of templates and fields, accelerate construction progress and shorten the completion period. It is applicable for concrete with early-strength and high-performance requirements and other concretes that need to enhance strength and improve long term performance.
3,Increase the concrete slump and improve its liquidity, applicable for ready-mixed concrete, pumping concrete, high-liquidity concrete, grouting material, etc.
4,Without air entraining. It is applicable for all grades of concrete with steam curing condition and natural maintenance.
