wetting/ dispersion

  • TYTAN Titanate Coupling & Dispersing Agents are molecular bridges at the interface between inorganic fillers (such as CaCO3, BaSO4, graphite, talc, carbon black, silica and metal oxides) and polymers (such as PP, PE, PVC, PBT, PET, ABS and rubbers). When incorporated into polymers, the coupling agent could improve filler loading, pigment dispersion, processability and composite mechanical properties to achieve the specification desired. As a comparison, silane coupling agents only reacts with hydroxyl groups on the filler surface via water condensation of silanol-siloxane process, therefore it is suitable for glass, alumina hydroxide, magnesium hydroxide etc. The advantage of titanate coupling agents is that they not only react with hydroxyls, but also the free protons on the inorganic interface, which results in the formation of organic monomolecular layers on the inorganic surface forming the bonding for polymers. Dosage is up to the property required and the filler type used is dependent on its surface area, the larger the surface area, the more Tytan titanate coupling & dispersing agent are needed. As a guide, the general dosage range is 0.2% ~ 2.0% by weight of filler.
  • Polyether polymer modification with acidic groups for dispersing in solvent-based paints. Specially developed for PVC, UPE and PU foam systems where it can help to disperse filler and inorganic pigment in the system with good viscosity reduction & extender dispersions.
  • High molecular weight dispersant with solid surface affinity groups. Gives excellent wetting to the fiberglass leading to faster wetting of resin to the fiber glass & eventually gives better bonding strength & performance in the final product.
  • Special block-copolymer for wetting and dispersing in solvent & water-based primers and high filler loads. Good viscosity  depresser and mattting.
  • Pigment synergist for pthalocyanine, carbon black and violet pigments. To be used in combination with a HMW dispersant. Lowers viscosity of the mill base, improves gloss, jetness & pigment stability.
  • Modified polyurethane polymeric dispersant for solvent-based systems. Higher molecular weight compared to 4046. Improves dispersing performance, especially with carbon black pigments to provide higher jetness. First choice for high end applications such as OEM, refinish and industrial coatings.
  • Modified polyacrylic polymeric dispersant for water-based systems. Improved version of 4560 that gives better viscosity depression on pigments, especially carbon blacks and transparent iron oxides. More effective dispersant for colorants within water-based systems.
  • Modified polyurethane polymeric dispersant for solvent-based systems. Improved version of 4070 with no crystallizing problem and supplied in higher solids (45%). Recommended for refinish, can coatings, dispersion of transparent iron oxide and other industrial coatings and pigment concentrate preparations.
  • BTX-free modified polyurethane polymeric dispersant for solvent-based systems. Very effective in inorganic, organic pigments and carbon black dispersion preparation. Very-effective 3-dimensional steric hindrance design allows for good stability for all pigments. Very good viscosity reduction and improved color strength.
  • Modified polyurethane polymeric dispersant for solvent-based systems. Supplied in 100% active form. Recommended for solvent-free systems where conventional wetting and dispersing agents cannot perform with organic pigments and carbon blacks. Extremely good compatibility with thermoplastic acrylic, NC and CAB. Great for ink dispersions also.
  • Fatty acid modified polyester emulsifier. It is recommended to improve color acceptance of colorants in base paints. The use in colored NC can improve the gloss. 96% active.
