In 1941 Gremolith Ltd. was founded in Bazenheid (Switzerland) and in the following years positioned itself successfully in the market. The production and the worldwide distribution of Galalith, an artificial material used in the button industry, provided the basis for the success. In the 60s the company already established a good reputation and started to invest in the development and production of resins. In 1976 the innovative actions in the foundry industry led, in collaboration with a German partner, to the founding of ASK Chemicals Gremolith AG. Enrooted in the region the company still has its office and production in Bazenheid and employs approximately 20 well qualified specialists. With their know-how and many years of experience, they develop and produce various resins for individual applications.
