Abstract

A medical grade adhesive comprises a mixture of at least one cross-linkable pressure sensitive adhesive component and at least one non-cross-linkable pressure-sensitive adhesive component, wherein the amount of each of said components is such that the resultant adhesive can adhere to human skin for a period of up to about 7-10 days but can be removed without causing trauma to the skin.

Claims (8)

1. A pressure sensitive adhesive formulation comprising a mixture of at least one self-cross-linkable acrylic adhesive component and at least one non-self-cross-linkable acrylic adhesive component; said at least one self-cross-linkable acrylic adhesive and said at least one non-self-cross-linkable adhesive provided in such relative amounts that said adhesive formulation can adhere to human skin for a period of about 7-10 days but can be removed without causing trauma to the skin.

2. The pressure sensitive adhesive formulation of claim 1 , wherein said self-cross-linkable adhesive is provided as a solvent-based adhesive solution that contains a cross-linking agent.

3. The pressure sensitive adhesive formulation of claim 2 , wherein said non-self-cross-linkable adhesive is provided as a solvent-based adhesive solution that does not contain a cross-linking agent.

4. The pressure sensitive adhesive formulation of claim 3 , wherein said self-cross-linkable adhesive solution and said non-self-cross-linkable adhesive solution comprise the same acrylic polymer.

5. The pressure sensitive adhesive formulation of claim 1 , wherein said self-cross-linkable adhesive and said non-self-cross-linkable adhesive are provided within about a 60:40 to about 40:60 weight:weight ratio (dry solids).

6. The pressure sensitive adhesive formulation of claim 5 , wherein said self-cross-linkable adhesive and said non-self-cross-linkable adhesive are provided in about a 50:50 weight:weight ratio (dry solids).

7. The pressure sensitive adhesive formulation of claim 1 , wherein said adhesive formulation can adhere to human skin for a period of about 7 days.

8. The pressure sensitive adhesive formulation of claim 1 , wherein said adhesive formulation can adhere to human skin for a period of about 10 days.
