Bentonite Clay

Bentonite clay is a natural layered aluminosilicate mineral dominated by montmorillonite, featuring powerful water-swelling capacity, thixotropy, colloidal gelation and pozzolanic reactivity. It serves as a multi-functional mineral additive widely used in cementitious mortar, concrete and both water-based & solvent-based coating systems.

🌱 Core Advantages in Mortar & Concrete

• Outstanding thixotropy and anti-segregation performance:
  Balances construction fluidity and static stability simultaneously, a core superiority over single thickeners. It’s fast gel reconstruction at rest to stop aggregates sinking, stratification and sagging on vertical surfaces.

• Plasticity & trowelability to improve workability:
  Boosts cohesiveness of stiff dry mortars, reduces dripping, no sticky to spatula and improves smooth finishing performance during plastering and tiling.

• Excellent Thickening & suspension function:
  Forms reversible 3D gel networks to adjust system viscosity, solving contradictions between brushing fluidity and vertical anti-sagging performance. Adsorbs and wraps pigment/filler particles via electrostatic force, preventing hard sedimentation, floating and color separation during long-term storage, extending coating shelf life.

• Temperature-resistant rheology stability:
  Viscosity barely fluctuates under high/low storage and construction temperatures.

• Crack resistance for thin-layer mortars:
  Suppresses rapid water loss and uneven shrinkage to minimize surface cracking of plaster and repair mortar.

• Excellent storage stability for coatings:
  Prevents irreversible hard sediment of heavy pigments like titanium dioxide; coatings can be homogenized easily by simple stirring after long standing.

• Wide compatibility:
  Compatible with Portland cement, gypsum, latex emulsion, alkyd resin, epoxy and various inorganic fillers; sodium bentonite for aqueous systems, organo-modified bentonite for solvent coatings.

• No negative impact on film gloss:
  Unlike cellulose thickeners, it rarely causes loss of surface gloss of decorative coatings at reasonable dosages.

• Non-toxic, eco-friendly & low carbon:
  Inert mineral without volatile toxic components; replacing cement reduces CO₂ emissions from clinker calcination, complying with green building standards.
