HC0613.53 – Acrylic PEG


Acryl PEG POSS® is a molecular union of both functional chemistry and inorganic-organic compositions.

Surface energy control, Wetting and plasticization. Additionally dispersion and rheological diluency can be realized in certain formulations.

The reactive acryl groups provide for cross linking while the peg arms serve as dispersants, plasticization, and gloss effects. The HC0613.53 provides a very effective balance of viscosity reduction, dispersion and cross linking.

Acryl 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.

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
