The Tip of the Week is presented by media sponsor Kamweld Technologies, Inc. based in Norwood, Mass.


Kamweld Product Manager Len Alter is back to share his experiences and this week he discusses corona treatment of thermoplastics, such as high-density polyethylene (HDPE), to overcome the material’s low surface tension. An example would be a plastic sign made of HDPE (not PVC, which does not require corona treatment) that needs lettering or paint added to it.


According to Mr. Alter, corona treatment creates an electrical field around the plastic sheet and changes its properties to allow for perfect adhesion.
