From the supplier: Alkoxide is formed when KOH is used to manufacture propylene oxide polyols. This reaction manufactures a monofunctional ether moiety which competes for propylene oxide with the polyhydric initiator. Unsaturation increases as a function of the urethane sealant's molecular weight. Unsaturation also decreases polyurethane's ability to withstand weather conditions.
