Anti-settling organoclay for marine coatings
Camp-Shinning Supply water based anti settling agent and water-based anti-settling additive for different paints and coatings.Speically in marine coatings.
Organoclay CP-24
CP-24 is a economical grade of organoclay rheological additive made from bentonite. It is used in solvent and resin systems covering low polarity to medium polarity range.
Advantages – Anti-settling organoclay additive for marine coatings
- Fine dispersion and particle size.
- Gel is very transparent and of light color .
- Thixotropy with low viscosity.
- Cost effective.
- Imparts particle suspension, sag resistance without impairing flow and leveling, preventing hard settling of pigment and fillers.
- Exerts strong film reinforcing action in organic binder systems.

Using
CP-24 disperses under high shear and requires a polar activator (30%~40%) for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 30%~40% of CP-24 in weight. Pre-gel procedure is as below.
- Charge solvent to mill
- Slowly add CP-24 (8-10% by weight of total pregel) to mill under agitation.
- Mix at high speed for 5 minutes.
- Add polar activator.
- Mix at high speed for 5 minutes.
Note: The suggested addition level of our organoclay and polar activator is based on our lab testing. Exact dosage for detail formulation should be based on user’s testing.
