Abstract

A method for bonding PEBA plastic composition with dissimilar materials. Also, composite articles made in accordance with the method. The method uses only water-borne adhesive compositions.

First claim

What is claimed is:

1. A method for bonding a first substrate comprising a blend of polyether block amide and styrene/maleic anhydride copolymer a second substrate, the method comprising:
cleaning a surface on the first substrate with a first aqueous cleaning solution comprising oxalic acid to form a first clean prepared surface;
applying an aqueous primer to the first clean prepared surface on the first substrate to form a primed surface on the first substrate;
applying a water-borne adhesive to the primed surface on the first substrate to form an adhesive-coated surface on the first substrate;
applying an aqueous primer to a second clean prepared surface on the second substrate to form a primed surface on the second substrate;
applying a water-borne adhesive to the primed surface on the second substrate to form an adhesive-coated surface on the second substrate; and
contacting the adhesive-coated surface on the first substrate with the adhesive-coated surface of second substrate to bond the first substrate and the second substrate.

2. The method of claim 1 , further comprising cleaning a surface of the second substrate with a second aqueous cleaning solution to form the second clean prepared surface.

3. The method of claim 2 , wherein the second aqueous cleaning solution comprises oxalic acid.

4. The method of claim 1 , further comprising drying the aqueous primer on the primed surface of the first substrate before applying water-borne adhesive thereto and drying the aqueous primer on the primed surface of the second substrate before applying water-borne adhesive thereto.

5. The method of claim 4 , further comprising drying the water-borne adhesive on the adhesive-coated surface of the first substrate and drying the water-borne adhesive on the adhesive-coated surface of the second substrate before contacting the adhesive-coated surface of the first substrate with the adhesive-coated surface of the second substrate to bond the first substrate and the second substrate.

6. The method of claim 5 , further comprising activating the water-borne adhesive on the adhesive-coated surface of the first substrate and activating the water-borne adhesive on the adhesive-coated surface of the second substrate before contacting the adhesive-coating surface of the first substrate with the adhesive-coated surface of the second substrate to bond the first substrate and the second substrate.

7. The method of claim 6 , further comprising pressing the adhesive-coated surface of the first substrate to the adhesive-coated surface of the second substrate after bringing the adhesive-coated first surface and the adhesive-coated second surface into contact.

8. The method of claim 1 , wherein the styrene/maleic anhydride in the blend of polyether block amide and styrene/maleic anhydride copolymer is unmodified.

9. The method of claim 1 , wherein the styrene/maleic anhydride in the blend of polyether block amide and styrene/maleic anhydride copolymer is esterified.

10. The method of claim 4 , wherein the styrene/maleic anhydride in the blend of polyether block amide and styrene/maleic anhydride copolymer is unmodified.

11. The method of claim 7 , wherein the styrene/maleic anhydride in the blend of polyether block amide and styrene/maleic anhydride copolymer is unmodified.

12. The method of claim 4 , wherein the styrene/maleic anhydride in the blend of polyether block amide and styrene/maleic anhydride copolymer is esterified.

13. The method of claim 7 , wherein the styrene/maleic anhydride in the blend of polyether block amide and styrene/maleic anhydride copolymer is esterified.
