Organic bentonite clay powder with good self-activated property

Organic bentonite clay powder CP-24  is a new style of organoclay rheological additive made from bentonite. Organophilic clays is used in solvent and resin systems covering medium polarity to high polarity range. It is adapted for aromatic solvent, ester, ketone, alcohol and resins in medium and high polarity such as two-component polyurethane, fluorocarbon coating, epoxy coating, zinc-rich coating etc.

Advantages

  • High purity, low silica content. The Quartz content is less than0.5%.
  • Fine dispersion and particle size.
  • Good self-activated property.
  • Gel is very transparent and of light color.
  • Wide application range including low polarity to high polarity systems.
  • Polar activator can be eliminated.
  • High anti-settling and anti-sag performance.

Application

Organic bentonite clay powder CP-24 is used in the following applications:

  • Paints including top grades paint, decorative paint, industrial

paint.anti-corrosion,container paint, marine paint and auto paint.

  • Printing
  • Sealants and adhesive.

Using

It can be added directly in powder under high shear condition. Addition level is commonly 0.1%~1.0% (7%-10% in greases) of total formulation by weight. in low and medium solvents, Polar activator is required to achieve better performance. The addition procedure is suggested as below.

  1. Add resin in solvent.
  2. Add CP-24 under slow agitation.
  3. Disperse under high speed for 10-15 minutes.
  4. Add polar activator (95% ethanol or 95% acetone)
  5. Disperse under high speed for 10-15 minutes.
  6. Add wetting agent and other additive.
  7. Grinding and next procedure.

If to make pre-gel, better efficiency can be achieved. Addition level in pre-gel is 8%-10% of total pre-gel in weight. Pre-gel procedure is as below.

  1. Add solvent or solvent mixture.
  2. Add CP-24  under slow agitation.
  3. Disperse under high speed for 5-10 minutes.
  4. Add polar activator.
  5. Disperse under high speed for 10-15 minutes.

Polar activator is suggested to be ethanol/water (95/5)or acetone/water (95/5). Dosage of polar activator is about 10%-35% of CP-24 by weight.

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.
