Abstract
Processes for treating polymeric surfaces to produce smooth, durable, slippery coatings which are able to withstand the rigors of sterilization and, long term exposure to human blood and other bodily fluids without substantial loss of their slipperiness. An article or device suitable as a wound drainage device coated in accordance with the process described is also disclosed.
Claims23
A process for treating an article or device having a polymeric surface to produce a smooth, durable, slippery coating comprising applying to the polymeric surface of the said article a combined solution of polyvinylpyrrdolidone (PVP) and N-trimethoxypropyl silyl polyethylenimine (PSO76) and then subjecting said article to the heat/dry cycle.
An article having a polymeric surface which has been treated to produce a smooth, durable, slippery coating, said coating being formed by applying to the polymeric surface of the said article a combined solution of PVP and N-trimethoxypropysilyl (PSO76) and subjecting said article or device to a heat/dry cycle.
