FILCO® JM 366 is an unsaturated polyester resin formulated in a non-ionic water emulsion. It's characterized by its highly unsaturated nature, which integrates a non-ionic emulsifier within the polymer matrix. This resin offers stability against hydrolysis and sedimentation, features a narrow distribution of particle sizes, and maintains high mechanical shear stability even in diluted emulsion forms.

Functions: Film Former

Chemical Family: Polyesters, Unsaturated Polyester (UPE)
