Abstract

Disclosed is an adhesive system that allows for a strong adhesion of a member to a surface, while also allowing for easy removal of the member after a prolonged period of attachment. A releasing agent can be included in an adhesive layer of the adhesive system. A heating system, such as an induction heating system, can be used to heat the releasing agent to activate it to assist in removing the adhesive system.

Claims

1. A system to remove an appliqué

comprising;

an aircraft substrate;

a multilayer pressure sensitive adhesive placed between an appliqué and

the aircraft substrate to substantially form a bond between the appliqué and

the aircraft substrate;

a releasing agent dispersed in a single layer of the multilayer pressure sensitive adhesive, the single layer located adjacent either the aircraft substrate or the appliqué

, wherein the releasing agent includes a constituent adapted to be selectively activated to change between a neutral form and an activated form, such that the activated form dissolves the adhesive;

a heat source operable to heat the releasing agent in order to activate the releasing agent.

2. The system of claim 1, further comprising:

an edge sealant adapted to be placed on the exterior of the appliqué

;

an edge sealant releasing agent dispersed in the edge sealant;

wherein the appliqué

includes an exterior and the edge sealant is positioned on the exterior of the appliqué

to assist in the bond between an edge of the appliqué and

the substrate.

3. The system of claim 1, wherein the single layer is located adjacent the aircraft substrate.

4. The system of claim 1, wherein the single layer is located adjacent the appliqué

.
