    摘要： A heat-activable powder adhesive composition for use in bonding a component to a surface such as glass is disclosed. The composition of the disclosed invention includes at least two polymers, at least one solid di- or poly-isocyanate in powder form, and a catalyst. Each of the two polymers has a melting point above 40° C. The two polymers are selected from the group consisting of di-functional polymers and multi-functional polymers. The preferred method of preparing the composition of the disclosed invention includes first forming three parts, including a first melted part comprising the polymers, a second melted part comprising the polymers and a catalyst, and a third part comprising the isocyanate. Once cooled, each of the first and second parts forms solid blocks which are fragmented and sieved. The three dry parts are then brought together to form the adhesive powder of the disclosed invention. The adhesive powder can be pre-applied to the attachment surface of a component to be bonded. The composition does not require either a deactivating agent or a blocking agent for deactivating the isocyanate or the catalyst nor does it require either a deactivated isocyanate or a deactivated catalyst.

    摘要： A method and an apparatus are provided for the production of heat-activable adhesive pellets that can be formed into elements for holding an article to a surface such as a glass surface. The apparatus and method for the manufacture of the heat-activable pellets include the steps of introducing at least a first component comprising at least one difunctional polymer with at least one multifunctional polymer into an extruder, heating the first component, introducing a second component comprising isocyanate and a powder flow enhancer (such as fumed silica) at a point downstream of the introduction of the first component, combining the first and second components in the extruder to form a flowable compound, pelletizing the extruded compound exiting the extruder by cutting to form heat-activable adhesive pellets, and drying the pellets. In one embodiment of the disclosed invention a catalyst is applied to the pellets to form catalyst-coated heat-activable adhesive pellets. In another embodiment of the disclosed invention a catalyst is added into the extruder to form catalyst-containing heat-activable adhesive pellets.
