With the outbreak of the Second World War, production is restricted, but can be largely maintained until 1943. In the summer of 1939, the offices were even modernised. In the July nights of 1943, however, the production facilities and the warehouse on the company premises were destroyed by bombs. Tragically, two employees were also killed while working as night guards. War and fire leave their mark, but also spur Rudolf Hensel to new thoughts. How can the protection of people and material be improved? The infernal chaos gives rise to the idea of developing fire-retardant paints that protect the material like a wall and are henceforth to become the focus of Hensel’s development.
