Product Properties And Characteristics

PropertyDetails
ThickeningImprove product viscosity, sag resistance, and adhesion to different substrates
Water RetentionReduce moisture loss, delay the absorption of water by the porous materials, conducive to cement hydration and longer opening hours
Anti-saggingImprove the thixotrophy of the product and prevent sagging on a vertical surface; ensure the stability of the final products.
rheology controlEnhance workability and smooth on-site application; Enhance final consistency
Open timeExtend the hardening time of the product; make the raw materials fully hydrated; improve the tensile strength and flexibility of the product
Surface activityFunction as surfactants in aqueous solution; Act as a protective colloid and emulsifier.
EmulsificationReduce the surface and interfacial tension and thicken the aqueous phase to ensure the stability of emulsion liquid
NonionicWithout ionic charge
SolubilitySoluble in water and organic solvents
PH stabilityStable in a range between pH 3.0-11.0

Main Applications And Product Benefits

  • Tile adhesives: MelaColl high viscosity grades are recommended for tile adhesive to effectively improve its adhesion, water retention, sag resistance and workability features.
  • Wall putty/skim coat: MelaColl medium viscosity products are recommended for the skim coat. It can improve product mixing, enhance product lubricity and workability. It can also prevent cracks and improve sag resistance, water retention, and open time of the construction.
  • ETICS/EIFS: Our products are widely used in EIFS adhesives and base coats to improve the adhesion and cohesion features of the products. It can enhance water retention, prolong open time, and improve construction workability and consistency.
  • Cement plaster: Our medium viscosity products are used in cement renders to improve the water retention, workability, sag resistance, final consistency and production rates.
  • Flooring system: Our low viscosity product is recommended for the application in self-leveling flooring compounds to improve the rheology (e.g. fluidity), leveling, and workability.
  • Gypsum-based building materials: Our medium viscosity products are recommended in gypsum applications to improve the workability, water retention, sag resistance and adhesion to different substrates.
  • Detergents: Our high viscosity grades are recommended for detergent application to control the thickening, rheology, emulsification, and optical clarity properties of the products.
