Properties Iron is an active drier only at elevated temperatures while it exhibits very poor drying activity at room temperature. Therefore, it is used extensively as a primary drier in baking – stoving systems where it provides durable flexible and high gloss films. When used in air drying alkyd coatings it improves through drying. The main disadvantage of iron is its dark colour; its high staining power and yellowing effect limit its use in dark coloured baking systems. Iron carboxylates also function as pigment wetting agents and help the fast and better grinding of carbon black pigments. Finally, it can be used as an adhesion promoter in the anti-corrosion coatings and as a replacement of lead in aluminium paints. Iron complexes are very potent redox catalysts in aqueous solutions unlike solvent based alkyds because in polar solvents and ambient conditions Fe+3 is easily reduced to the necessary hydro peroxide initiator compounds. Iron can also substitute manganese as combustion catalyst, especially at ferric state, exhibiting high efficiency with much lower toxicity. Applications Active drier in baking systems.

Toggle High Contrast Toggle Font size About Us Products Downloads Contact Dispersing Agents The stabilization of solids in the liquid phase of the paint can be achieved with the use of dispersing agents. These additives produce a long-term stable, fine and homogeneous distribution of the inorganic and the organic particles in polar and non polar liquid phases. The whole process is called de-flocculation of solid particles and the substances used for this process are high and low molecular surfactants. As surfactants are in principle amphiphilic compounds that they have one or more “adhesion groups” which can dock with the solid particle by anionic (electrostatic effect) and/or non anionic (steric effect) and a more-or-less long segment which can be solvated. This class of additives has a marked effect on a series of different, essential characteristics of the paint formulations. So whenever their full action is achieved, they decrease viscosity, increase colour intensity, prevent flocculation flooding and floating of the solid particles and increase levelling, leading to higher gloss. Our company has developed dispersing agents for water and solvent born coatings distributed under the trade name DISPORGAN. Powered By Web-support
