Alkyd resins chemically modified with polyamide resins are often used as thixotropic agents for air-drying non-drip paints and high — solid alkyd-based paints. Polyamide modified alkyds form a highly viscous mass that becomes reversibly free-flowing when shear force is applied. The mechanism for developing thixotropy is based on hydrogen bonding along the polymer structure.
