Rheology modifiers

Rheology modifiers CP-24  is a new style of organoclay rheological additive made from bentonite. Organoclay is used in solvent and resin systems covering medium polarity to high polarity range. Rheological additives 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.

Rheology modifiers, which are divided into volumetric bentonite and water-based bentonite, which is what we often call inorganic water-based spraying, it is a montmorillonite clay after strict purification and modification, it is a highly efficient Water-based inorganic gel and solvent-based gel, it is widely used in solvent-based systems and water-based systems to thicken suspension and control rheology.

This is a white or off-white powder. It is non-toxic and tasteless, relatively soft, and its mutation is particularly prominent. It has a relatively wide range of pH values. It is widely used in some different types of paints. At the same time, it is also widely used in some cosmetic lubricants. At present, the largest application field is in oil field drilling.

If you want to write specifically, it is mainly used as an anti-settling agent, latex stabilizer and rheological additive in water-based systems, and will be used in latex paint, real stone paint and some other types of crystals.

At present, our main packaging form is kraft paper bag or polyethylene woven bag. At the same time, we also use valve bag packaging and 50 packs. Finally, we will customize the packaging according to the needs of customers. Usually We recommend that you store it in a ventilated and dry place, which has a better meaning for its performance guarantee.

The following table is the parameters of our products for your reference, but here we would like to point out that in the bentonite of the water-based system, its bulk density is generally 0.6~0.8 grams per cubic meter.In the end, please use your experimental results as the standard.

Of course, we also have some types of organic bentonite, which are suitable for medicine, toothpaste, food and other industries. They are used as a sorbent in medicine, a binder for ointment flakes, a decomposer and stabilizer, and an additive for toothpaste.

In some daily chemical products, Rheology modifiers is used as a suspending agent, thickener, and dispersant. Of course, in some dry mortar putty powder, there is also a large amount of water-based organic bentonite used.

In the use of putty powder, we must admit that Rheology modifiers most prominent characteristics are its strong water saturation and excellent lubrication. It can improve the effect of the official image and optimize the entire production formula, because our product has good viscosity, it can effectively reduce the addition ratio of other products, which is conducive to reducing the production cost of human capital.

Rheology modifiers  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 of Organic bentonite clay

Rheology modifiers 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.

Rheology modifiers 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.
