Naphthalene Superplasticizer (High-Solid Powder)

High-solid powder · Built for shipping and dry mixes

Naphthalene Superplasticizers (FDN / BNS) Powder Dosage: 0.40% – 1.00% by weight of binder

Overview

High-solid naphthalene powder is spray-dried from the liquid product. Its high active content makes transport and storage significantly cheaper than the liquid form, which is why it is a common choice for dry-mix systems and distant markets.

Key benefits

  • High active content — low cost per unit of dosage
  • Powder form ships easily with no leakage or freezing risk
  • Blends directly with cement and fillers on dry-mix production lines
  • Good solubility, dissolves on contact with water

Application notes

Store in dry conditions and reseal after opening. For dry-mix systems, pre-blend with other powders. The low-alkali grade is available where alkali content is restricted.

Typical uses

Dry-mix mortar, grouts, refractory castables, gypsum products, general concrete.

Typical applications

  • Dry-mix mortar
  • Grouts
  • Refractories
  • General concrete
