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.
Claims25
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.
The method according to any of the preceding claims, wherein the oxidative-heat process is applied selectively on selected parts of the product.
The method according to any of the preceding claims, wherein the silicone structure is an external urinary catheter.
The method according to any of the preceding claims, wherein the oxidative-heat process is a corona treatment.
A method for applying an adhesive material to a cured silicone structure, comprising curing adhesive together by a silicone tie-layer.
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.
An electrode for corona treatment with a spacing between the electrode edge and the inside surface.
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.
