Petrarch PS077 (N-triethoxysilylpropyl) o-polyethylene-oxide urethane United Chemical Technologies Silyl-modified polymers ADHESIVE Because silicones are oxygen-permeable, flexible and have inert properties they are used in numerous medical devices. Industrial silicone applications are typically coupling agents for bonding elastomers to polar substrates, adhesive systems and silicone lubricants. Multiple bonding opportunities with both inorganic substrates and polymer matrices make these materials desirable in many adhesive bonding formulations. (N-Triethoxysilylpropyl) O-Polyethylene- Oxide Urethane (N-triethoxysilylpropyl)o-polyethylene-oxide urethane. Used in adhesive systems. Provides multiple bonding opportunities with both inorganic substrates and polymer matrices.
