FILCO® JS 208 is an unsaturated polyester-epoxy resin, available as a non-ionic water dispersion, utilized as a film-former in glass fiber sizings. It boasts several key characteristics, including a narrow distribution of particle sizes, ensuring consistency. The resin offers an extended shelf life due to its resistance to hydrolysis, which is attributed to its fine particle size. Additionally, it exhibits high mechanical shear stability when diluted, contributing to its effectiveness in various applications within the glass fiber industry.
