Name:
BP-283  Rheology Modifier
Type: 1.Rheology Modifier for solvent based system



BP-283 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity.

 

 

1.      Advantages:

 

☆ High gelling efficiency over low to medium polarity organic liquids.

☆ Ideal thixotropic and anti-sagging property.

☆ High viscosity and excellent thickening property over a wide temperature range.

☆ Imparts particle suspension, preventing hard settling of pigment and fillers.

☆ Exerts strong film reinforce action in organic binder systems.

4.      Incorporations:

BP-283 belongs to the conventional type of organoclay group, which requires mechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.

 

Polar Activator: Dosage of polar activator (such as 95%ethanol, 95%methanol, acetone or propylene carbonate) is 30%-45% by weight of BP-283.

It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result
in poorer viscosity development.

 

Recommended Procedures:

1)   Heat the specific oil to 60℃~70℃。

2)   Add BP-283 (7-10% by weight of total formula),mill for 5-10min.

3)   Add polar activator(3% by weight of total formula), then add other modifier,mill for 25-30min.

4)   Using pump for getting through colloid grinding or homogenizer.

5)   Remove air,filtrate and package.

 

In other systems like inks, heating is not necessary. Increasing dispersion speed,prolong dispersion time or enhance the temperature will improve the efficiency of BP-283.

5.      Recommended Levels:

The amount of BP-283 rheology modifier required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-2.0% based on the total
formulation weight.
