Abstract
The present invention provides an improved bonding system including an adhesion promoter that may be used to help adhesively bond two or more components together. The preferred use of the present adhesion promoter is in a transportation vehicle (e.g., automobile), and more particularly in an engine assembly for use in such vehicles. The present invention includes a bonded automobile engine assembly including at least one plastic component, an adhesive that bonds the plastic component to at least one separate component, and an adhesion promoter between the adhesive and the plastic component. Fasteners for attaching components are optionally employed. In one specific example, an intake manifold including a plastic component is bonded to an engine assembly.
Claims26
A bonded automotive vehicle assembly, comprising:
- at least one plastic component;
- an adhesive for bonding the plastic component to at least one different component;
- and
- an adhesion promoter between the adhesive and the plastic component, comprising at least:
- a polyhydroxy compound;
- and
- a hydroxy group containing unsaturated monomer.
A method of manufacturing a bonded automotive vehicle engine assembly, comprising:
- combining a polyhydroxy compound and a hydroxy group containing unsaturated monomer in a solvent to form an adhesion promoter;
- applying the adhesion promoter to at least one plastic component;
- and
- bonding the plastic component to a second component with an adhesive.
A bonded automotive vehicle engine assembly, comprising:
- at least one plastic intake manifold component;
- an adhesive for bonding the intake manifold component to at least one different component;
- and
- an adhesion promoter between the adhesive and the plastic intake manifold component, comprising at least:
- resorcinol;
- and
- hydroxyethyl (meth)acrylic monomer.
