- Functions:Film Former
- Chemical Family:Polyesters, Unsaturated Polyester (UPE)
FILCO® 366 is a highly unsaturated polyester resin meticulously dispersed within a non-ionic water dispersion, dedicated to serving as a film former in glass fiber sizings. Its appearance is that of a milky liquid. Key product characteristics encompass its high unsaturation, integration of a non-ionic emulsifier within the polymer, stability against hydrolysis and sedimentation, a narrow particle size distribution, and high mechanical shear stability, even in diluted emulsions.
