Contact SupplierAct as oxidation catalysts, as their metal soaps exhibit more than one oxidation state. Primary driers catalyse cross linking of the resin and in the process hydroxyl, carbonyl and carboxylic groups are formed
Through driers:
Ensure that a coating dries at a uniform rate throughout the body of the film. Primary driers without the presence of through driers would mainly dry the surface of the film, whilst the coating underneath would remain wet. Through driers are used to ensure that the coating dries at a uniform rate throughout the body of the film not just at the surface. Through driers link fatty acid chains via oxygen-metal-oxygen bridges leading to cross-links.
Auxiliary driers :
Modify the effect of other driers but do not demonstrate any drying action on their own.
Product | Metal Content | Non-Volatile Content | Benefits and Uses |
---|---|---|---|
Cobalt Octate 12% | 12 | 68 | Strongly promotes surface drying. It is Bluish Violet in color, but low effect on color on the dry paint film. It produces less discoloration in wet paint and upon ageing of dried paint. |
Cobalt Octate 10% | 10 | 57 | Strongly promotes surface drying. It is Bluish Violet in color, but low effect on color on the dry paint film. It produces less discoloration in wet paint and upon ageing of dried paint. |
Cobalt Octate 8% | 8 | 50 | Strongly promotes surface drying. It is Bluish Violet in color, but low effect on color on the dry paint film. It produces less discoloration in wet paint and upon ageing of dried paint. |
Cobalt Octate 6% | 6 | 3 | Strongly promotes surface drying. It is Bluish Violet in color, but low effect on color on the dry paint film. It produces less discoloration in wet paint and upon ageing of dried paint. |
Cobalt Octate 3% | 3 | 12 | Strongly promotes surface drying. It is Bluish Violet in color, but low effect on color on the dry paint film. It produces less discoloration in wet paint and upon ageing of dried paint. |
