ABSTRACT:
A method for the reactive coating or reactive encapsulation of fluidizable, organic or inorganic, anisotropic or isotropic substrates with a cross-linking, thermostable and insoluble thermoset by spraying onto substrates a cationically curing one-pot liquid resin system comprising a cationic initiator, which method comprises fluidizing the substrates in a fluidized-bed coater at a temperature above the activation temperature of the cationic initiator and then injecting the one-pot liquid resin system into the fluidized-bed coater through a spraying device, the one-pot liquid resin system having a gelling time of from 1 to 60 seconds at from 100 to 150.degree. C., results in unagglomerated substrates having a cross-linked, thermostable and homogeneous coating.
