Anwendungen & Verwendung
Verwenden
Methacrylamide is a reagent used in the production of polymers and copolymers. It is also used as a raw material in the production of chemicals for industrial and professional use such as textiles, leather, fur, bulk, large scale chemicals (including petroleum products), fine chemicals, formulation [mixing] of preparations and/or re-packaging (excluding alloys), building and construction work, electricity, steam, gas, water supply and sewage treatment.
