- the material When determining appropriate components for the activatable material, it may be important to form the material such that it will only activate (e.g., flow, foam or otherwise change states) at appropriate times or temperatures. For instance, in most applications, it is undesirable for the material to be reactive at room temperature or otherwise at the ambient temperature in a production environment. More typically, the activatable material becomes activated to flow at higher processing temperatures. As an example, temperatures such as those encountered in an automobile assembly plant may be appropriate, especially when the activatable material is processed along with the other components at elevated temperatures or at higher applied energy levels, e.g., during painting preparation steps. Temperatures encountered in many coating operations (e.g., in a paint curing oven), for instance, range up to about 250°C or higher.
- the activatable material can be accomplished according to a variety of new or known techniques.

- the activatable material is formed by supplying the components of the material in solid form such as pellets, chunks and the like, in liquid form or a combination thereof.
- the components are typically combined in one or more containers such as large bins or other containers.
- the containers can be used to intermix the components by rotating or otherwise moving the container. Thereafter, heat, pressure or a combination thereof may be applied to soften or liquidize the components such that the components can be intermixed by stirring or otherwise into a single homogenous composition.
- the activatable material may be formed by heating one or more of the components that is generally easier to soften or liquidize such as the polymer based materials to induce those components into a mixable state. Thereafter, the remaining components may then be intermixed with the softened components. Depending upon the components used, it may be important to assure that the temperature of the components remains below certain activation temperatures that might cause the activatable material to activate (e.g., form gasses, flow or otherwise activate), cure (e.g., harden, stiffen or otherwise change states) or both.
- activate e.g., form gasses, flow or otherwise activate
- cure e.g., harden, stiffen or otherwise change states
