Abstract:
A method for the reactive coating or reactive encapsulation of fluidisable, 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 fluidising the substrates in a fluidised-bed coater at a temperature above the activation temperature of the cationic initiator and then injecting the one-pot liquid resin system into the fluidising coater through a spraying device, the one-pot liquid resin system used having a gelling time of from 1 to 60 seconds at from 100 to 150.degree. C., wherein coatings that are cross-linked on the particles are obtained without agglomeration of the individual coated particles while the coating is being cross-linked.
