Abstract: The present disclosure concerns a system for curing a wet coating of a coated substrate, the system comprising: a curing room having a curing room inlet and a curing room outlet, the curing room being configured to receive the coated substrate being introduced at the curing room inlet thereof along a first displacement axis, the system comprising a conveyor assembly for conveying the coated substrate through the curing room along a second displacement axis transverse to the first displacement axis, wherein the system further comprises a gas catalytic IR system, provided in the curing room, for producing an infrared radiation to partially cure the wet coating while the coated substrate is in the curing room. The disclosure concerns also a corresponding process.

Abstract: Systems and processes for curing a wet coating of a coated substrate are disclosed. The system includes a ventilation system and a curing room configured to receive the coated substrate being displaced along a displacement axis and includes at least an upstream curing section and a downstream curing section. The upstream curing section includes an upstream catalytic infrared heating system for producing an upstream infrared radiation at an upstream radiation intensity to heat and partially cure the wet coating while the coated substrate is being displaced through the upstream curing section. On the other hand, the downstream curing section includes a downstream catalytic infrared heating system for producing a downstream infrared radiation at a downstream radiation intensity, being lower than the upstream radiation intensity, to further cure the wet coating while the coated substrate is being displaced through the downstream curing section for producing a cured coating.

Abstract: A catalytic heating apparatus 10 for drying, curing, polymerization and cross-linking of organic coatings and compounds, which includes a catalytic combustion chamber 1, a fuel supply 6, a regulating valve for controlling the flow of fuel 4, an injector for mixing the fuel with air thereby providing a uniform fuel-air mixture to the combustion chamber, a casing 5 connecting the fuel supply to the combustion chamber, and an air injection ring and a connector for connecting an air source to the air injection ring. The air injection ring may be a tube of circular cross-section, with regularly-spaced holes drilled on its surface so as to direct a flow of air towards the object being dried. The purpose of air injection is to facilitate evacuation of vapors from the surface of the object being dried. Drying is therefore achieved by a combination of radiation from the emitting surface and convection from the air injection ring.

Abstract: The present relates to a portable catalytic drying apparatus for use in applications such as drying, curing, polymerisation and cross-linking of organic coatings and compounds. The apparatus comprises a catalytic combustion chamber where a co-current lean mixture of fuel and air is combusted, a casing connecting a fuel supply to the combustion chamber, a regulating valve for controlling the flow of fuel, and an injector for mixing the fuel with air thereby providing a lean mixture of uniform fuel-air concentration.
