# Commission Implementing Decision (EU) 2020/2009 of 22 June 2020 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for surface treatment using organic solvents including preservation of wood and wood products with chemicals (notified under document C(2020) 4050) (Text with EEA relevance), Division BAT 8: In order to reduce energy consumption and the overall environmental impact from drying/curing processes, BAT is to use one or a combination of the techniques given below.

Extent: E+W+S+N.I.

The selection of the drying/curing techniques may be restricted by the substrate type and shape, product quality requirements and the need to ensure that the materials used, coating application techniques, drying/curing techniques and off-gas treatment systems are mutually compatible.
Technique
Description
Applicability
(a)
Inert gas convection drying/curing
The inert gas (nitrogen) is heated in the oven, enabling solvent loading above the LEL. Solvent loads of > 1 200 g/m3 nitrogen are possible.
Not applicable where dryers need to be opened regularly.
(b)
Induction drying/curing
Online thermal curing or drying by electromagnetic inductors that generate heat inside the metallic work-piece by an oscillating magnetic field.
Only applicable to metal substrates.
(c)
Microwave and high-frequency drying
Drying using microwave or high-frequency radiation.
Only applicable to water-based coatings and inks and non-metallic substrates.
(d)
Radiation curing
Radiation curing is applied based on resins and reactive diluents (monomers) which react on exposure to radiation (infrared (IR), ultraviolet (UV)), or high-energy electron beams (EB).
Only applicable to specific coatings and inks.
(e)
Combined convection/IR radiation drying
Drying of a wet surface with a combination of circulating hot air (convection) and an infrared radiator.
Generally applicable.
(f)
Convection drying/curing combined with heat recovery
Heat from off-gases is recovered (see BAT 19 (e)) and used to preheat the input air of the convection dryer/curing oven.
Generally applicable.
