Methacryl PEG POSS® is a molecular union of both functional chemistry and inorganic-organic compositions.
Surface energy control, Wetting and emolliancy. Additionally dispersion and rheological diluency can be realized in certain formulations.
The reactive methacryl groups provide for high crosslinking while the peg arms serve as dispersants, plasticization, and gloss effects. The HC0713.31 system provides higher crosslink capacity that related methacryl-peg heterocages.
Methacryl PEG POSS® is provided in neat form. It is intended to be utilized as an additive. At additive concentrations compatibility is expected with a wide range of resins and monomers bearing similar chemical functionality. Compatibility testing is recommended for higher concentrations.

Viscosity (@25°C): 310-330 mPa s
RI (@19.2 °C): 1.470
Solubility: Water, alcohols, acetates, and nearly all aromatic/aliphatic epoxy, acrylic, and urethane resins.

Methacryl PEG POSS® is a provided as a mixture of cages sizes 8, 10, 12. The organic groups are randomly distributed around each cage core. The molar ratio of methacryl and PEG groups is 5:3 for HC0713.53
The distribution of cage size, and functionality around the cage core is analogous to that for functional copolymers.
Heteroleptic Cage POSS are represented by the catalog designation HC. The structure shown is idealized and should not be considered exact. MOLAR RATIOS AVAILABLE
