HC1110.71 Vinyl iso-Octyl POSS


Vinyl iso-octyl POSS® is a molecular union of functional olefin chemistry and inorganic-organic compositions.


Hardness enhancement with optical clarity for peroxide, hydroxylation, thiol, and UV/EB cured formulations.  Toughening and compatibilization can also be imparted by the iso-octyl group.  This additive is capable of free radical induced UV cure.

*unique wetting adhesion to polyolefins*


Vinyl iso-octyl POSS® should be considered as a replacement for generation 1, vinyl POSS® (OL1170, OL1160).  It is a highly adhesive and soluble system that imparts a plethora of vinyl-reactivity to olefin-curable formulations.  As a liquid it is readily miscible with a variety of olefinic resins, oligomers, and monomers.
