Description
Methacryl i-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 i-Octyl POSS® is a molecular union of both chemistry and inorganic/organic composition.
Free radical and addition cure. The combination of reactivity and hydrophobicity provides for interfacial compatibility 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-Butyl 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.
