Sodium Naphthalene Formaldehyde (SNF) 18% Sodium Sulfate Grade
Non-air-entraining SNF superplasticizer for concrete, cement systems and oil well cementing.
SNF 18% Sodium Sulfate Grade is a free-flowing brown powder non-air-entraining superplasticizer for building cement, concrete formulations, oil well cementing and industrial dispersing use.
This grade is widely used where strong concrete workability, cement particle dispersion and practical water reduction are required in cost-sensitive construction systems.
It is also suited to selected industrial dispersing applications.
Key Performance Functions
High Water Reduction
Reduces water demand and helps improve strength development.
Concrete Workability
Improves fluidity, pumping and placing performance.
Dispersing Performance
Disperses cement particles and supports uniform concrete formulation.
Cost Optimization
Allows optimization of cement and water usage under validated mix design.
Non-Corrosive to Rebar
Does not contain chloride-based corrosive ingredients under normal specification.
