New Product Announcement: Aerospace Adhesives

TUESDAY, FEBRUARY 20, 2024


Global coatings company PPG recently announced the release of two new adhesives to its aerospace portfolio, PPG PR-2940 epoxy syntactic paste adhesive (ESPA) and PPG PR-2936.

According to PPG, PR-2940 can help bond the internal structures of an aircraft, while PR-2936 utilizes the properties of a shim and sealant to attach the outer skin of an aircraft to the internal structures.

“We are excited to add these adhesive technologies to our product offering,” said Sean Purdy, PPG global director, coatings and sealants, Aerospace. “They will provide our aerospace customers with significant performance benefits as well as sustainability advantages through lightweighting.”

PPG states that PR-2940 ESPA adhesive is a lightweight potting compound for both original equipment manufacturers (OEM) and maintenance, repair and overhaul (MRO) customers on secondary aircraft structures.

The coating reportedly fills and reinforces the honeycomb structures used to build an aircraft’s internal components, including the inner wing structure, galley, lavatories, overhead bins and flooring.

Global coatings company PPG recently announced the release of two new adhesives to its aerospace portfolio, PPG PR-2940 epoxy syntactic paste adhesive (ESPA) and PPG PR-2936.

Additionally, the PR-2936 adhesive is reportedly used by OEMs to attach the metallic or composite skin of an aircraft to the internal structures of the fuselage, tail assembly, wings and stabilizers.

This epoxy-based adhesive can reportedly cure at ambient temperatures and was created to fill gaps or irregularities between the surfaces of the primary and secondary structures. It reportedly combines mechanical strength with flexibility and microcracking resistance across a large operating temperature window.
