Disclosed herein are free flowing coated particles and low temperature methods of making same. Each particle has a curable coating disposed upon a substrate. The substrate is a particulate substrate including an inorganic material, a particulate substrate including an organic material, a composite substantially homogeneous formed particle including a first portion of an at least partly cured binder and filler particles, or a hybrid particle having an inorganic particle as a core and a composite coating including at least partially cured resin and filler. The curable coating includes a continuous phase including a curable liquid resin and reactive powder particles embedded or adhered to the continuous phase. The reactive powder particles typically include one or more of a resole phenolic-formaldehyde resin, a novolak phenolic-formaldehyde resin, a polyester resin, an acrylic polymer resin, a urethane resin or an epoxy resin. A method including applying a coating including the continuous phase including the curable resin and reactive or non- reactive powder particles embedded or adhered to the continuous phase.
