Lubricious silicone surface modifying treatments and/or coatings for modifying the frictional or slip surface characteristics of shaped elastomeric articles are provided in surface modifications including a coating or surface modifying composition comprising: n a crosslinkable silane having the formula:n n wherein R is selected from unsubstituted and halogen-substituted aliphatic, cycloaliphatic, aromatic and alkyl aromatic groups having less than or equal to about ten carbon atoms, R¹ is independently selected from hydrogen, hydroxyl, halogen, alkoxy and acyloxy groups, R² is independently selected from hydrogen, alkyl and halogen-substituted alkyl groups, n is an integer of 1 to 3 inclusive, and m = 3 - n . The cured, highly crosslinked, three dimensional silicone coatings are effective at reducing the coefficient of friction of surfaces of shaped elastomeric articles, such as those frequently used in medical devices, by a factors of from about 50% to about 80% as compared with the same uncoated substrates. |
