FILCO® 7607 is an unsaturated polyester resin offered in a non-ionic water emulsion, designed as a film-former for glass fiber sizings. Its appearance is akin to that of a milky liquid. Notable characteristics of this product include a built-in non-ionic emulsifier within the polymer, a narrow particle size distribution, an extended shelf life due to hydrolytic resistance and fine particle size, high mechanical shear stability when the emulsion is diluted, and exceptional hydrolysis and sedimentation stability across a wide pH range.

Functions: Film Former

Chemical Family: Polyesters, Unsaturated Polyester (UPE)

Processing Methods: Spray Lay-up
