## Abstract

Using an oxidative process it is made possible to apply an adhesive material to silicone. The process is controlled, allowing selective oxidative treatment to a silicone structure enabling treatment to the inside of a tubular structure.

## Claims

### Claim 1

A method for applying an adhesive material to silicone comprising
(a) applying an oxidative process to the silicone;
(b) applying an adhesive to the oxidized silicone surface.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the oxidative process is performed by a process selected from a group consisting of oxidative-heat treatment, UV light, E-beam, gamma-irradiation and chemical oxidative treatment.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the oxidative-heat treatment is performed by a treatment selected from group consisting of corona treatment, plasma treatment and flame treatment.

### Claim 4 (depends on 1, 2, 3)

The method according to any of the claims 1-3, wherein the silicone forms a tubular body.

### Claim 5 (depends on 1, 2, 3, 4)

The method of any of the claims 1-4, wherein the adhesive material is a polar adhesive material.

### Claim 6 (depends on 5)

The method of claim 5, wherein the polar adhesive is based on acrylics, polyether, polyvinylether, polyurethane or polyvinylpyrolidone.

### Claim 7 (depends on 1, 2, 3, 4, 5, 6)

The method of any of claims 1-6, wherein the adhesive material is an acrylic pressure sensitive adhesive.

### Claim 8 (depends on 1, 2, 3, 4, 5, 6, 7)

The method according to any of claims 1-7, wherein the silicone is cured silicone.

### Claim 9 (depends on 8)

The method of claim 8, wherein the silicone structure is fully cured.

### Claim 10 (depends on 8)

The method of claim 8, wherein the silicone structure is partly cured.

### Claim 11

The method according to any of the preceding claims, wherein the oxidative-heat process is applied selectively on selected parts of the product.

### Claim 12 (depends on 11)

The method of claim 11, wherein the oxidative-heat process is applied selectively on the inside of a silicone external catheter.

### Claim 13

The method according to any of the preceding claims, wherein the silicone structure is an external urinary catheter.

### Claim 14

The method according to any of the preceding claims, wherein the oxidative-heat process is a corona treatment.

### Claim 15

A method for applying an adhesive material to a cured silicone structure, comprising curing adhesive together by a silicone tie-layer.

### Claim 16

A tubular body being produced of silicone, comprising
at least an encircling inner band of oxidized silicone, and
an outer encircling band of non-oxidized silicone,
wherein the outer encircling band at least covers the encircling inner band.

### Claim 17 (depends on 16)

A tubular body according to claim 16, wherein the tubular body is an urisheath.

### Claim 18 (depends on 16, 17)

A tubular body according to any of claims 16-17, comprising an adhesive on the oxidized encircling inner band.

### Claim 19

### Claim 20

A silicone urisheath comprising an adhesive bound to a part of the first side of the urisheath after a selective oxidative process of this part of the first side of the urisheath.

### Claim 21 (depends on 20)

The silicone urisheath according to claim 20, wherein the oxidative process is performed by a process selected from a group consisting of oxidative-heat treatment, UV light, E-beam, gamma-irradiation and chemical oxidative treatment.
