Slow SPUR growth

摘要

Silanes have been used in polyurethanes for about 30 years, starting with their use as adhesion promoters in the late 1960s, Crompton's Sadler said. Japanese firm kaneka started making MS (modified silylated) polymers in the late 1970s-but these generally have polyether backbones and are not marketed as PUs, Sadler pointed out.
