Methacrylpropyl iso-octyl POSS® is a clear viscous liquid hybrid molecule with an inorganic silsesquioxane core and organic groups attached at the corners of the cage. Methacryl iso-octyl POSS® is a molecular union of both chemistry and inorganic organic composition.
Free radical and addition cure. The combination of reactivity and hydrophobicy provides for interfacial compatibility, and and surface modification. The crosslinking capability in combination with i-octyl provides for resistance to moisture uptake and low surface energy while retaining optical transmission.
The i-octyl groups are more plasticizing than the i-butyll groups present on the HC0709 system.
APPLICATIONS: Surface energy control, Hydrophobic wetting and moisture barrier. Additional use as a compatibilizer can be realized in certain formulations.
