Benefits of using combined drier mixtures: − Storage stability- avoiding degradation resulting in constant drying performance − Simplified handling and dosing. − Stock only one drier – easier logistic control – reserve funds. −Lower VOC - avoid addition of unnecessary extra solvent. One disadvantage of using mixtures of driers is that these are often been absorbed from pigments or other components of the system leading to loss-of-dry. In order to avoid this effect it is recommended to use an efficient wetting or loss-of-dry agent like zinc or calcium neutral driers before the addition of the mixture drier. These additives would be preferably absorbed by the pigments or by any other complexation substances. Powered By Web-support
