Toronto, Ontario — AkzoNobel has announced the launch of a new 2K solvent-borne primer for OEM exterior plastic parts to aid in the adhesion challenges for customers.
The solvent-borne primer comes in conductive and dark grey, and is designed so that there is no need to switch products in production, thereby reducing complexity and increasing efficiency on the paint line.
The low polarity for plastics such as polypropylene causes low surface energy and poor adhesion, notes AkzoNobel. As a result, this makes plastic parts such as bumpers, rocker panels and contrasting features challenging to coat.
AkzoNobel further reports that its “new multi-substrate ESP-950 primer belongs to a new technology family developed by AkzoNobel and will provide adherence to a broader range of automotive substrates, including polypropylene grades less than 20 percent talc and polycarbonate blends.”
Ed Hillborne, Global Product Marketing Manager for AkzoNobel’s Automotive OEM Coatings business notes that “there is an increasing focus on vehicle weight reduction and emissions, which is accelerating the growth of the market for automotive plastics, but conversely, the adhesion of coatings is becoming more and more difficult.
“Committed to creating products that power process efficiency, AkzoNobel’s new multi-substrate ESP-950 primer creates a paint system with wider versatility in adhesion on plastics, with lower dry film thickness in application than existing primers. It is compatible with automotive application lines—wet-on-wet or bake-on-bake technology—and fulfills most OEM specifications.”
