CLAYMINTON 54 rheological additive can be incorporated into organic liquids using either high shear or high- speed types of equipment. Optimum gelling efficiency is obtained when the proper degree of mechanical, chemical and thermal energy is applied to the system. The mixing equipment should provide the necessary degree of mechanical and thermal energy. The required chemical energy is supplied by a polar additive.
Polar Additives
The polar additive acts as a wedge to help open up the clay platelets and make them more readily available
for developing maximum gelation. A polar additive must be used to help insure against changes in gel
strength and obtain highest gelling efficiency.
| Types of Polar Additives |
Relative Amount Required based on the weight of dry CLAYMINTON 58 additive |
| Methanol/Water (95/5%) | 33% |
| Propylene Carbonate (100%)* | 33% |
| Propylene Carbonate/Water (95/5%) | 33% |
| Ethanol/Water (95/5%) | 50% |
| Acetone (100%)* | 60% |
| Octylphenoxy Polyethoxy Ethanol* | 75% |
CLAYMINTON 54 additive is initially mixed with the major organic components followed by incorporation of the polar additive. The optimum high speed dispersion techniques for pigments are also optimum for
CLAYMINTON 54 additive. One proven successful approach for developing optimum performance in an organic system would be to add the following in the order listed:
(1) Take a portion of the total solvent/resin system (properly balanced) and mix.
(2) Add CLAYMINTON 54 additive and mix 10 minutes.
(3) Add the required amount of polar additive and mix 5 to 10 minutes.
(4) Add the pigments and disperse.
(5) Incorporate the remaining solvent/resin and other ingredients following standard practice.
If surface active agents are essential, add shortly after dispersion has begun. It is essential that CLAYMINTON 54 additive be subjected to shear forces (to produce full gel development) prior to possible interference from the surface active agent.
High Shear Equipment (ball mill, roller mill, colloid mill, homogenizer, etc.)
procedure
In general, the to be followed is similar to that shown above for high-speed dispersion. However, it has been found useful at times to pre-dampen the CLAYMINTON 54 additive with the required level and type of polar additive in cases where a ball mill, roller mill or pebble mill is employed. The pre-dampened gellant is then incorporated in a manner which is appropriate for the particular piece of equipment being used.
The amount of CLAYMINTON 54 rheological additive required depends upon the type of organic system and the degree of thickening or other properties desired.
In paints, for example, from 2 to 3.5 pounds per 100 gallons is recommended for a gloss enamel, while a stipple paint may need between 6 and 9 pounds per 100 gallons of paint.
In cosmetics, levels of 1 to 3% CLAYMINTON 54 additive based on the total formulation weight, are effective for introducing a thixotropic character and controlling syneresis in an end-product. Similar levels will also function as an auxiliary emulsifier in water/mineral oil systems.
