Reactive Gas Technology Offers Performance and Design Flexibility
by Prakash Iyer, Inhance Technologies Commodity polymers, such as polyethylene and polypropylene, often are chosen over engineering or high-performance polymers due to factors that include lower costs, availability and broad processing latitude. These materials, however, often exhibit very low surface energy, which creates poor adhesion characteristics and leads to poor … [Read more...] about Reactive Gas Technology Offers Performance and Design Flexibility
Q&A: Corona Discharge Surface Treatment
by Bruce Stobbe, Corotec Corporation How does corona discharge surface treatment work? A corona discharge treating system utilizes a high-voltage discharge to effect a molecular change in the surface structure of the material being treated. This effect is not visible, but causes the surface to be more chemically receptive to inks, coatings and adhesives. Inks and coatings … [Read more...] about Q&A: Corona Discharge Surface Treatment
Gas-Phase Surface Pretreatments for Plastics Adhesion
by Scott Sabreen, The Sabreen Group, Inc. Surface pretreatments are used to promote adhesion between difficult-to-bond plastic substrates and adhesives, coatings and inks. Among pretreatments, "gas-phase surface oxidation" processes are proven highly effective, economical and environmentally safe. The selection of which method is best for any given application can be … [Read more...] about Gas-Phase Surface Pretreatments for Plastics Adhesion
