Abstract: A silicone-polyolefin composition is disclosed. The silicone-polyolefin composition comprises (A) a polysiloxane, (B) a functionalized polyolefin, and (C) a curable silicone elastomer component. The polysiloxane (A) comprises an average of at least one functional group X per molecule, and the functionalized polyolefin (B) comprises an average of at least one functional group Y per molecule, where the functional group X and functional group Y are reactable to form a bond therebetween. A silicone-polyolefin blend, a curable composition comprising the silicone-polyolefin blend, a cured product of the curable composition, and methods of preparing the silicone-polyolefin blend, curable composition, and cured product are also disclosed.

Abstract: A hand tool which can be a multibit fastener driver with an in-handle bit storage system. A fastener driver which can have bit storage system which can have a bypass angle which provide an exit path for a bit being removed from storage which is free of intersection with obstacles and achieves efficient removal of bits from bit storage chambers. A bit storage system which can have one or more bit retainers and/or one or more bit grips which reversibly maintain a bit in storage when the fastener driver is in any orientation. Methods, means and processes for effective and efficient bit storage and release of bits for use by an operator.
