Abstract

Provided are methods for making textured implantable materials made from two part RTV silicone foams and having a desired color or tone without the need for dyes or colorants.

Claims

1. A method of making a material having a preselected color and suitable for implantation in a mammal, the method comprising:

providing a silicone base component;

providing a catalyst for the base component; and

mixing the base component with the catalyst at about 50 rpm for about 30 seconds to achieve a foam solution; and

allowing the foam solution to polymerize to achieve a polymerized silicone foam material having a bronze brown tone having RGB color code values R=about 184 to about 225, G=about 114 to about 140, and B=45 to about 55.

2. The method of claim 1 that excludes the addition of any colorant, dye or similar agent.

3. The method of claim 1 wherein the viscosity of the foam solution is between about 4300 mPas to about 4700 mPas.

4. The method of claim 1 wherein the viscosity of the foam solution is about 4500 mPas.

5. An implantable material useful as a component of a breast implant made by the method of claim 1.

6. A method of making a breast implant shell comprising:

providing a silicone base component;

providing a catalyst for the base component; and

mixing the base component with the catalyst at about 50 rpm for about 30 seconds to achieve a foam solution; and

allowing the foam solution to polymerize to achieve a polymerized silicone foam material having a bronze brown tone having RGB color code values R=about 184 to about 225, G=about 114 to about 140, and B=45 to about 55.

7. The method of claim 6 that excludes the addition of any colorant, dye or similar agent.

8. The method of claim 6 wherein the viscosity of the foam solution is between about 4300 mPas to about 4700 mPas.

9. The method of claim 6 wherein the viscosity of the foam solution is about 4500 mPas.

10. An implantable material useful as a component of a breast implant made by the method of claim 6.
