Ludwig Hatschek

About Inventor. Ludwig Hatschek (1856 - 1914) began manufacturing asbestos board and asbestos gaskets (asbestos) in Vöcklabruck. In order to make the asbestos board hard so it can be used to produce panels, Hatschek experimented with various binding agents. The addition of Portland cement in 1900 led to the sought-after achievement.
