Abstract: A composition that forms an insulating layer contains an epoxy-thiol-based binder. Because the expansion rate of the composition is relatively high, coatings having the layer thickness required for the relevant fire resistance duration can be applied in a simple and rapid manner, and it is possible to reduce the layer thickness to a minimum while still achieving a good insulating effect. The composition is particularly suitable for fire-protection, in particular as a coating for metal and non-metal substrates, e.g., steel components such as supports, beams, and truss members, to increase the fire resistance duration thereof.

It is characteristic in this case that a low-methane material stream is withdrawn from the H2 separation column and is then applied to the CO/CH4 separation column as reflux.
