Product Description

Sulfonate Melamine Formaldehyde (SMF) is a high-range water reducer (superplasticizer) powder based on sulfonated melamine formaldehyde resin. It is specifically designed for gypsum-based and cement-based mortars that demand high strength and superior surface quality.

This non-air entraining product exhibits strong adsorption and dispersion effects for gypsum, significantly helping mortars achieve a perfect, smooth finishing surface.

Main Applications

Concrete Engineering

  • Precast components: Enhances early strength and shortens demolding time (pipe piles, railway sleepers, wall panels).
  • High-strength concrete: Improves density and durability for grades C50 and above.
  • Self-leveling & Pumped concrete: Improves flowability and reduces pumping resistance.
  • Steam-cured concrete: Boosts performance significantly during steam curing.

Building Materials

  • Dry-mix mortars: Self-leveling mortars, non-shrink grouts, and tile adhesives.
  • GRC products: Glass Fiber Reinforced Concrete fluidity and mechanical strength.
  • Gypsum-based materials: Increases hardness and reduces water demand.
  • Colored concrete: Ensures surface finish quality and color uniformity.

Packaging & Storage

Packing: 25kg/bag (eco-friendly valve paper bag).

  • Store under cool and dry conditions.
  • Prevent moisture, high temperatures, and compression to avoid clumping.
  • Seal residual product immediately to prevent moisture ingress.
  • Shelf life: 12 months from the production date in original packaging.
