A process for the production of strongly adherent coatings on an inorganic or organic substrate is provided, wherein in a first step

Process for the production of strongly adherent coatings

The invention relates to a process for the production of strongly adherent coatings on an inorganic or organic substrate, in which process in a first step: a) the inorganic or organic substrate is subjected to the action of a low-temperature plasma discharge, a corona discharge, high-energy UV radiation or electron radiation, the radiation or discharge is then discontinued, in a further step: b) at least one electron- or H-donor, each containing at least one ethylenically unsaturated group, is applied to the inorganic or organic substrate in vacuo or at normal pressure and reacted with the free radicals formed there, and c1) the substrate so precoated with coinitiator is coated with a composition comprising at least one ethylenically unsaturated monomer or oligomer and a photoinitiator, and the coating is cured by means of electromagnetic and/or ionizing radiation; or c2) the substrate so precoated with coinitiator is coated with a composition comprising at least one ethylenically unsaturated monomer or oligomer and one or more thermally activatable initiators, and the coating is cured thermally. The invention relates also the use of electron- or H-donors, for example amines, thioethers or thiols, having at least one ethylenically unsaturated group in the production of such layers and to the strongly adherent coatings themselves.

This invention relates to a process for the preparation of UV protective coatings by plasma-enhanced vacuum deposition, using hydroxyphenyl-s-triazines as UV absorbers. This invention also relates to the use of hydroxyphenyl-s-triazines in plasma-enhanced vacuum depositions and to the substrates coated by this process.

Process for the preparation of UV protective coatings by plasma-enhanced deposition

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.
