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.

FAQ Section

 

Q1: Can SMF be used with PCE-based superplasticizers?
---- Yes, but conduct compatibility tests to avoid over-dispersion.

 

Q2: Does SMF delay setting time?
---- Minimal effect (1-2 hrs delay for OPC). Use retarders for longer delays.

 

Q3: Is SMF suitable for hot weather concreting?
---- Yes, but consider a retarded SMF type (>4 hrs setting delay).

 

Q4: How does SMF compare to NSF superplasticizers?
---- Advantages: Better sulfate resistance, less foaming.
---- Limitations: Lower water reduction than PCE.

 

Q5: Shelf life of SMF powder?
---- 24 months in sealed, dry conditions.
