MPC-based modifier Lipidure®-CR3001 for SILICONE

MPC-based surface modifier

The Lipidure®-CR3001 is a surface modifier for metals and silicone rubber that can provide excellent hydrophilicity and excellent biocompatibility.

Hydrophilization of Silicone Rubber Surface

A silicone rubber sheet was modified with Lipidure®-CR3001. Contact angle (air in water) of the CR3001-modified surface was measured to confirm the improvement of hydrophilicity.

Lipidure®-CR3001 impart excellent
hydrophilicity to silicone rubber surface.

Coating Procedure

Mechanism of Immobilizing Lipidure®-CR3001

MPC : A Source of Ultra High Hydrophilicity

MPC is a methacrylic monomer having phosphoryl choline group.
Phosphoryl choline is a hydrophilic part of phospholipid, which
exists on cell membrane.
 Phosphoryl choline coating imparts excellent biocompatibility
and excellent hydrophilicity onto the substrate.

Alkoxy silane: A crosslinking point

  1. Alkoxy silane group is hydrolyzed in an acidic condition to form silanol group [-Si(OH)3].
  2. In coating process, hydrogen bond is formed between the silanol and hydroxy group on the substrate.
  3. Dehydration condensation occurs in heating process to form Si-O covalent bond.
