The following methods can effectively bond PP:
Method 1: Use flexible glue with high solid content, as shown in the figure, to seal more firmly. And it should be able to adapt to the requirements of wet or waterproof environment. This glue generally has a certain flexibility, has good adhesion to the PP surface, and can be waterproof, sealed, and resistant to chemical corrosion.
Method 2: Use a modified acrylic structural adhesive. Of course, ordinary acrylic structural adhesives cannot bond PP. There is a special structural adhesive that can attract each other with PP molecules, and has low odor and no solvent.
