Product Description

Sulfonated Melamine Formaldehyde (SMF) is a high-performance, synthetic polymer-based superplasticizer widely used in concrete and mortar formulations. As a naphthalene-free alternative to traditional water reducers, SMF enhances workability, strength, and durability while reducing water content.

Application

 

1. Precast & Prestressed Concrete

• Improves flowability for intricate molds, reducing voids.

• Enhances early strength for faster demolding.
   

2. Self-Leveling Underlayments & Floors

• Ensures high slump flow (600-750mm) without segregation.
   

3. Shotcrete (Wet-Mix Process)

• Reduces rebound and improves adhesion to vertical surfaces.
   

4. Glass Fiber Reinforced Concrete (GRC)

• Enhances fiber dispersion in thin-section products.
   

5. Marine & Sulfate-Resistant Concrete

• Low chloride content prevents rebar corrosion.
   

6. High-Performance Concrete (HPC)

• Enables low w/c ratios (<0.35) for 80+ MPa strength.

 

 

Our Advantages

 

-- Naphthalene-Free: Eco-friendly alternative to NSF superplasticizers.
-- Sulfate Resistance: Ideal for marine environments.
-- Compatibility: Works with PCE-based admixtures for synergy.


 

Usage Guidelines

 

• Dosage: 0.5-1.5% by cement weight (optimize via trial mixes).

• Mixing: Pre-dissolve in water for uniform dispersion.

• Compatibility: Works with OPC, slag cement, and PCE admixtures.

 

Package and storage

 

• 25 kg moisture-proof bags or 500 kg jumbo bags.

• Shelf Life: 24 months in dry conditions (<50% humidity, 10-30°C).

 

Why Choose SMF?

 

• Cost-Effective: Lower price than PCE superplasticizers for comparable performance.

• Eco-Friendly: No naphthalene, low formaldehyde residue.

• Proven Performance: Used in high-speed rail, bridges, and nuclear plants.
