Abstract
Due to the reduction in costs and elimination of process steps, Industries manufacturing acrylic fibres prefer solution polymerization. In this technique, tile fibres are prepared in a form suitable for wet and dry spinning. The commonly used solvents include aqueous solution of thiocyanates of alkali metals at higher concentrations, It is reported that the structures and reactors in the manufacturing plant suffer from severe corrosion leading to huge tests for replacement of the same, To find the suitable coating material to protect the Structures in such atmosphere, four representative film forming polymers were chosen and the performance of their coatings was studied under different conditions of concentrations and temperatures, Four coatings based on polyacrylates, polyamide cured epoxy, polyurethane and chlorinated rubber were evaluated and among them the coating based on chlorinated rubber resin is found to give better protection in thiocyanates atmosphere
