Application
3-Methacryloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methylsilane (SiGMA) is a siloxane macromere, which can be used in the formation of hydrogels for the preparation of contact lenses.
This monomer is commonly used in the formulation of research silicone hydrogel contact lenses and other research ophthalmic devices. Silicone monomers are preferred for the synthesis of research ophthalmic materials due to their high oxygen permeability.
