Celeritas Unveils High-performance Grades of Organophilic Clays for Paints & Coatings

Published on 2012-10-29. Author : SpecialChem

Celeritas Chemicals, a specialty chemicals and materials supplier based in Southlake, TX, has introduced 3 new high-performance grades of organophilic clays specifically designed for the paint and coatings industry.

Organoclays are popular viscosity modifiers for paints and resins requiring thixotropic flow. Smectite-based organoclays are modified with a quaternary ammonium salt which facilitates compatibility with a variety of organic solvent systems. In suspension, organoclays form a shear-thinning gel which stabilizes pigments and fillers. These purified bentonite clays enable homogeneous application of paints and coatings, while minimizing the need for polar activators and excessively high shear during dispersion.

CELCHEM 31743-09, 31744-09 and 31745-09 are organoclays (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity. CELCHEM Organoclays offer the following advantages for paint and coatings formulators

  • High gelling efficiency over low to medium polarity organic liquids
  • Easy incorporation.
  • Consistent in rheology and thixotropy development
  • Excellent sag resistance and control of viscosity
  • Produce gel with light color and high transparency

CELCHEM 31743-09, 31744-09 and 31745-09 belong to the unconventional type of organoclays group, being easy-to-disperse, self-activated organoclays. They typically do not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks. However, certain applications may benefit from the addition of a polar activator to achieve the desired viscosity.

Typical applications include:
Acrylic paint
Chlorinated rubber paint
Solvent epoxy paint
Wooden paint
Nitro lacquer
Varnish
Adhesive
Primer paint
Zinc-rich paint
Alkyd paint
Sealant
Industrial paint
Inks (Mineral oil)
Polyester paint
Road paint
Inks (Nitro)
Anti-corrosion paint
Lubricating grease
