FILCO® 348HP is an epoxy resin formulated within a non-ionic water emulsion, designed specifically as a film-former within glass fiber sizings. Its appearance resembles that of a milky liquid. Key product characteristics encompass its composition as a pure epoxy resin, a narrow particle size distribution, stability against hydrolysis and sedimentation, high mechanical shear stability even in diluted emulsions, and, notably, a very high solid content.

Functions: Film Former

Chemical Family: Epoxy & Epoxy Derivatives

Compatible Polymers & Resins: Epoxies (EP), Phenolic Resins, Unsaturated Polyester (UPE)
