The present disclosure relates to a method of coating a non-conductive substrate, said method comprising the steps of: a) applying a coating composition to the substrate, wherein the coating composition comprises: i) at least one unsaturated compound, ii) a thermal initiator comprising an organic peroxide, iii) a photoinitiator, and iv) at least one pigment, wherein the coating composition is free of accelerator, is capable of decreasing the activation energy of the thermal initiator, and is free of Co compounds, b) exposing the coating composition to UV light effective to start polymerization of the unsaturated compound, and c) exposing the coating composition to microwave heating effective to decompose the thermal initiator, wherein step c) is performed either simultaneously with step b) or sequentially after step b).

An improved inside of can curing technology is provided. One implementation uses narrowband, semiconductor produced infrared energy which is focused into the inside of the can to affect a very high-speed curing result and will directly impact the coating covering the inside walls of the can to rapidly cure the coating. De-tempering and annealing of the aluminum can body does not have time to occur, thus leaving a stronger can with the same amount of aluminum or a can of the same strength but with less aluminum. It is also possible to eliminate the natural gas fueled oven that is the current standard and replace it with a completely hydrocarbon-free curing alternative that has superior performance. This high powered radiant, narrowband energy will be digitally controlled to introduce only the needed heat and to not overheat the can.

A method for coating a tile element includes providing a tile element made of a compressed fibre material having a porosity in the range of 0.92-0.99 and applying a water-based coating material to a side edge surface of the tile element extending between two opposite major surfaces of the tile element. The applying is performed by an applicator head of a continuous vacuum coating apparatus that applies the water-based coating material to the side edge surface of the tile element and removes excess through a vacuum. The water-based coating material is applied at a feeding rate of the tile element relative the applicator head in the range of 25-150 m/min. The water-based coating material forms a coating layer including an outer coating layer and an inner coating layer penetrating the side edge surface. The inner coating layer has penetration depth of at least 100 μm.
