Polyamides are reacted with alkyd resins to give thixotropic (nondrip) consistency. The Existing thixotropic technology often fails due to too weak structures. Also paints based on higher solid systems are more sensitive to tinting systems based on water, surfactants & other solvents, the thixotropic structure is hence not stable any more, also they lose their structure forming ability at temperatures above 45 C. This is due to poor association capability of H-bonding network of polyamide based modifiers. So to get the desired rheological properties, if stabilizers are added in the final paint formulation, such paints could also become sensitive to changes in weather conditions and may not remain stable over a period of time. The answer to this problem is to incorporate the rheological properties into resin instead of paint formulation. So there is a need for stronger & more stable thixotropic structures. If a polymide resin based on aromatic amide moieties was reacted with a dimeric fatty acid, it could be used to develop alkyd resins which show superior gel forming properties. Thus a new family of thixotropic alkyd resins for decorative applications has been developed.)
