Open the CIPO recordAbstract From the Canadian patent
The invention is a method for making an article containing an adhesively bonded joint by first placing the surfaces to be bonded in the path of an intense energy beam, such as a laser beam for a short, duration to modify the surfaces. Then an adhesive is applied to the modified surfaces and the joint is completed. The inventive method results in stronger and more durable bonds relative to untreated surfaces and relative to prior surface treatments such as solvent cleaning. The invention is also an article made using the above method.
