Abstract
Low concentrations of a liquid silanol terminated polydiorganosiloxane with a number average molecular weight less than about 1000 extend the working time of tin-catalyzed moisture curable organosiloxane compositions without substantially decreasing the cure rate of the composition or adversely affecting the physical properties of cured materials, particularly elastomers, prepared using these compositions.
