Abstract

A lubricating composition includes an emulsion of a noncuring polysiloxane, a surfactant and water. Preferred polysiloxanes include a polar group, most preferably an aminoalkyl or carboxylalkyl terminating group. Preferred surfactants are copolymers of polysiloxane and polyoxyethylene. A metal article such as a needle, blade, cannula or quidewire includes a coating of the polysiloxane and the surfactant which renders the article surface lubricious. The article may be in a sliding relationship with a plastic article in an assembly such as a catheter-quidewire or a catheter-cannula assembly. The plastic portion of the assembly may also include a lubricant. The invention includes a method of making the lubricated article.

Claims

1. A metal article having thereon a lubricious coating comprising a noncuring polysiloxane lubricant selected from the group consisting of the formula ##STR3## wherein R₁ is NH₂ NHR₂ or COOH, R₂ is lower alkyl of 1 to 4 carbon atoms, n is 2 to 4, and x is an integer sufficient to give the lubricant a viscosity of about 10 to 2,000,000 centistokes, and a polyoxyethylene polysiloxane copolymer surfactant.

2. The article of claim 1 which is a guidewire.

3. The article of claim 1 which is a cannula.

4. The article of claim 1 which is a blade.

5. The article of claim 1 which is a needle.

6. The article of claim 1 wherein said coating further comprises an antibacterial agent.

7. A metal article having thereon a coating comprising a noncuring aminopropyl terminated polysiloxane lubricant selected from the group consisting of the formula ##STR4## wherein R₁ is NH₂ NHR₂ or COOH, R₂ is lower alkyl of 1 to 4 carbon atoms, n is 2 to 4, and x is an integer sufficient to give the lubricant a viscosity of about 10 to 2,000,000 centistokes, and a polyoxyethylene polysiloxane copolymer surfactant.

8. A method for lubricating a metal article comprising:

a) providing an emulsified lubricating composition which includes water, a polyoxyethylene polysiloxane copolymer surfactant and a polysiloxane lubricant selected from the group consisting of the formula ##STR5## wherein R₁ is NH₂ NHR₂ or COOH, R₂ is lower alkyl of 1 to 4 carbon atoms, n is 2 to 4, and x is an integer sufficient to give the lubricant a viscosity of about 10 to 2,000,000 centistokes;

b) applying a coating of said composition onto a surface of a metal article; and

c) removing said water from the coated metal surface to give a lubricated surface.

9. The method of claim 8 wherein said applying is performed by dipping said article into said composition.

10. The method of claim 8 wherein said applying step is performed by spraying said composition onto said article.

11. A method for lubricating a metal article comprising:

a) providing an emulsified lubricating composition which includes water, a polyoxyethylene polysiloxane copolymer surfactant and an aminopropyl terminated polysiloxane lubricant selected from the group consisting of the formula ##STR6## wherein R₁ is NH₂, R₂ is lower alkyl of 1 to 4 carbon atoms, n is 2 to 4, and x is an integer sufficient to give the lubricant a viscosity of about 10 to 2,000,000 centistokes;

b) dipping a metal article into said composition;

c) withdrawing said article from said composition to give a coating on said article; and

d) evaporating the water from the coating on the article to give a lubricated surface.
