Abstract: A stirrer for stirring a curable composition extracted from a squeezable container may include a body extending along a stirrer axis. A slot may be defined in the body along the stirrer axis. The slot may be configured to retain or squeeze at least a portion of the squeezable container. A total length of the slot may be less than 80% of a total length of the body. The stirrer may further include a tab extending from the body, which may have a substantially polygonal contour. The slot may extend to a teardrop-shaped end facing the tab. The slot may extend along a zigzag line. The tab may be held during engagement of the squeezable container with the slot to extract the curable composition and during stirring. The body may defining a tubular section defining the slot. The stirrer may further include a scoop extending from the tubular section.

Abstract: A liquid additive delivery composition for introducing an additive into a curable silicone composition may include a liquid carrier and at least one additive. The liquid carrier may include one or both of polyvinyl acetate or polyvinyl alcohol.

Abstract: Rosin esters are provided. The rosin esters can exhibit improved color (e.g., the rosin ester can have a neat Gardner color of 4 or less), improved oxidative stability (e.g., when 1000 ppm or less of an antioxidant is present in combination with the rosin ester, the rosin ester can exhibit an oxidative-induction time at 130° C. of at least 30 minutes), improved color stability (e.g., the rosin ester can retain a neat Gardner color of 5 or less when heated to a temperature of 160° C. for a period of three hours), or combinations thereof. Also provided polymeric compositions comprising the rosin esters, as well as methods of making the rosin esters.
