COMMET
paint drier
can be supplied in various concentrations, metal blends and solvents according to customers' requirements.
COMMET Barium
Barium Octoate is used as an auxiliary drier in combination with primary driers like Cobalt and Manganese. It also improves gloss and prevents the adsorption of primary driers and thus inproves the drying stability during long storage. Barium also acts as wetting agent for pigments and fillers.
COMMET Bismuth
Bismuth Octoate can be used to replace Zirconium in paint applications where low temperatures and high humidity conditions prevail.
It is also used as an EP-Additive to replace Lead and also for Polyurethane Catalysis.
COMMET Lead
Lead Octoate is used mainly in industrial paint applications. Its use has been limited because of environmental effects. Lead promotes an even through drying and in combination with Calcium and Barium it prevents precipitation of difficult to dissolve Lead compounds. In conjunction with Butyltitanate Lead is used as an accelerator for the hardening of silicon resins.
COMMET Calcium
Calcium Octoate is used as an auxiliary feeder drier and prevents the adsorption of primary driers resulting in improved drying stability.
COMMET Cobalt
Cobalt Octoate is the most active primary drier and is used in conjunction with auxiliary and through driers to promote an even surface and through drying. Care needs to be exercised when dosing Cobalt in order to prevent a too fast initial drying which would result in surface wrinkling.
COMMET Manganese
Manganese Octoate is the second most important primary drier. It can be used as a Cobalt replacement in darker coloured paints where discolouration due to the dark brown Manganese colour is not important. High humidity may however lower the effectivity of Manganese as well.
Manganese is also used in combination with Cobalt in the offset printing ink applications.
COMMET Zinc
Zinc Octoate reduces rapid film formation and therefore improves through drying. It prevents wrinkling and is used in combination with primary and auxiliary driers. Zinc can be applied as a fungicide and in the formulation of PVC stabilizers.
COMMET Zirconium
Zirconium Octoate is only effective as an auxiliary drier in combination with primary driers. It promotes surface and through drying. It has been extensively used to replace lead because of environmental effects.
