Methacrylpropyl iso-butyl 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-butyl 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-butyl provides for resistance to moisture uptake and low surface energy while retaining optical transmission.
The i-butyl groups are more reinforcing than the i-octyl groups present on the HC0710 system.
APPLICATIONS: Surface energy control, Hydrophobic wetting and moisture barrier. Additional use as a compatibilizer can be realized in certain formulations.
