Description

Description générale

3-[Tris(trimethylsiloxy)silyl]propyl methacrylate (TMSPM) is a silane-modified methacrylate characterized by its unique siloxy functional groups, which impart hydrophobicity and thermal stability. This compound serves as a versatile monomer in polymer synthesis, enabling the formation of siloxane-containing polymers with enhanced mechanical properties. Its excellent adhesion properties make it suitable for use in coatings, adhesives, and sealants.

Application

3-[Tris(trimethylsiloxy)silyl]propyl methacrylate can be used:

• As a silicone containing monomer to synthesize hydrogels for Opthalmic medical devices such as contact lenses with enhanced mechanical properties. Addition of TMSPM increases the oxygen permeability of the contact lens without affecting light transmission.
• As a precursor to fabricate dissolved oxygen sensor by embedding a highly stable and highly hydrophobic fluorinated matrix via free radical polymerization.
• To fabricate bio-based polymers for anti-stain and oil resistant textile coatings. The addition of TMSPM significantly enhances the oil repellence property of the coating.
