Petrarch PS901.5 Poly(acryloxypropylmethyl)siloxane United Chemical Technologies Silicone (Si) ADHESIVE >> Radiation Curing (UV/EB) 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. Acryloxypropyl-functional silicones undergo UV and visible light polymerization in the presence of photoinitiators such as ethylbenzoin. Poly(acryloxypropylmethyl)siloxane Poly(acryloxypropylmethyl)siloxane. Includes cyclics. Used in adhesive systems. Undergoes UV and visible light polymerization in the presence of photoinitiators such as ethylbenzoin.
