Surface Texturing to Improve Bond Strength

Q: I am having a hard time bonding polyethylene. Will texturing the surface of my substrate with micro-blasting improve the bond adhesion?

A: Creating a texture on the surface will help with adhesion, however, the surfaces must be free of any dust or particles prior to bonding. An IPA wipe should be sufficient for cleaning. With some hard to bond plastics like polypropylene, silicones, HDPE, etc., this kind of abrasion may have minimal impact for bond strength.
