Dry powder paint binder

A method of forming a dry powder paint binder from milk or plant proteins and other natural materials comprises a shearing operation to produce consistent, homogeneous and uniform particles. The binder may be mixed with pigments and mineral fillers (such as kaolin, magnesium silicate and calcium carbonate) to form a dry powder paint. Other ingredients may include preservatives (such as zinc oxide and potassium sorbate), fungicides, antifoaming agents (such as silica sand), cellulosic thickeners, polysaccharide dispersants, and activators (such as calcium hydroxide, ammonium carbonate, and borax).

These cyclic oligomeric precursors exhibit dynamic properties to reversibly dissociate yielding isocyanate and amine components which polymerize to yield the polyureas, such as linear, branched or cross-linked polyureas. This method and system has advantages over conventional methods that utilize two-component systems. Such two-component systems require the segregation of the isocyanate and amine components to prevent premature or too rapid polymerization. The resulting polyureas are useful for a variety of applications including coatings. 2. A cyclic oligomer or polymer according to corresponding to formula (Ia).3.
