SULPHONATED NAPHTHALENE FORMALDEHYDE (SNF)
SULPHONATED NAPHTHALENE FORMALDEHYDE (SNF) – High-Performance Superplasticizer for Concrete and Construction
Sulphonated Naphthalene Formaldehyde (SNF) is a high-range water-reducing admixture widely used in the construction industry, particularly in cement and concrete applications. The Russian-origin SNF offered in 25 Kg Box packaging is known for its excellent dispersing properties, making it an ideal choice for producing high-strength, flowable concrete with reduced water content.
This product is suitable for applications requiring early strength gain, improved workability, and enhanced durability.
