CAT 003
EXTRA WHITE CLAY (ECONOMY) |
This grade is reasonably white and free from impurities and can be used as an economical substitute of CAT-052 in various cost sensitive applications e.g. putties & primers. |
| |
CAT 004
EXTRA FINE WHITE PLASTIC CLAY
|
This grade is hard china clay having semi-reinforcing properties and high plasticity due to its very small average particle size. It is easily wettable & dispersible in aqueous solutions and has anti setting characteristics. It is an excellent filler for: - |
|
|
PAINTS |
Water based and emulsions. |
| RUBBER |
Checks retardation due to basic pH. |
|
| |
CAT 005
EXTRA FINE REINFORCING CLAY |
This clay has been specially processed to a very fine particle size and surface characteristics by modification of its basic structure. It has a very low BD and high oil absorption, unmatched by any mineral filler. It is highly suitable for: - |
|
PAINTS |
As a reinforcing agent - replaces ppt. silica partially e.g. EVA Footwear sheets. |
| RUBBER |
For gloss reduction in matt-finishes, control of consistency (rheology) besides acting as a low bulking filler.
|
| INSECTICIDES |
As a superior substitute for mineral fillers. Serves dual purpose as a better carrying agent and provides free flow properties. Due to excellent dispensability especially suited for WDPs. |
