Water Reducer
SNF Naphthalene-Based Superplasticizer
SNF naphthalene-based superplasticizer is a concrete water-reducing admixture in the Qiandao New Materials range. The brochure presents two SNF options: FDN-I and FDN-II (slow-setting). Their dosage ranges, setting behavior, air-content limits, strength ratios, and performance descriptions differ, so the selected grade should be tested with the intended cementitious materials and construction conditions.
