Baybond® XP 2728 is an anionic/non-ionic polycarbonate-polyether urethane polymer that is used as the film-forming component in glass fiber sizes. This product has a non-volatile content (1g / 1h / 125°C) of 58 - 62, a flow time at 23°C, (4mmcup) of < 90, and a pH value of 7-9. Baybond® XP 2728 was developed for the sizing of glass fibers used to reinforce thermoplastics, particularly polyamide. Glass fiber sizes based on Baybond® XP 2728 are characterized by their outstanding film-forming properties and very good adhesion. The product exhibits outstanding hydrolysis resistance and colorfastness, and is also very stable against shear forces.
