The invention relates to a dry free-flowing composite of a sub-micron polymer binder particles and interactive materials, and articles formed therefrom. The polymer particles are formed from a dilute latex polymer and blended with interactive materials, then the blend is spray-dried, to form a dry blend in which less than 10% of all polymer particles are in an agglomerated form. The polymer is preferably a polyvinylidene fluoride, such as Kyblock® PVDF from Arkema. The dry blend will be used to form articles and coatings by many means, for example forming a three dimensional article by heat and pressure, it can be redispersed into an aqueous coating composition, or can be electro-coated onto a substrate.
