FILCO® 368 is a saturated polyester resin in a non-ionic water emulsion, functioning as a plasticizer in sizing glass fiber. It appears as a milky liquid with main product characteristics such as medium-low molecular weight, non-ionic emulsion, narrow particle size distribution, and excellent compatibility with both polyester and PVAC emulsions.

Functions: Film Former, Plasticizer

Chemical Family: Polyesters
