Low-VOC Adhesive Bonding Primer
Project Number: J-01-OC-025

The commercial industry accounts for the majority of primer usage and has taken the lead to qualify low-VOC primers for use on commercial aerostructures. Primers for structural adhesive bonding are widely used in the aerospace industry to optimize the service life of bonding components by protecting pretreated surfaces from contamination, enhancing environmental resistance at the bond interface, and improving overall bond performance.

The objective of this project is to demonstrate, validate and qualify the commercially acceptable low-VOC adhesive bonding primer across all affected military platforms.

Presently, the primary project activities are to identify and engage affected weapon systems managers and depot process owners and prepare to identify critical performance requirements for military aircraft using adhesive bonding primers. A project kickoff meeting was held on April 19, 2001. As the project scope become better defined, technical documents such as a JTP will be posted on this website.

Successful completion of this project will result in a low-VOC adhesive bonding primer qualified for use at defense contractor sites participating in this project and all affected military aircraft. It is anticipated that participation in this project will reduce technical risk in qualifying a low-VOC adhesive bonding primer and sustaining maintenance costs, and reduce pollution without disregarding structural adhesive bonding primer quality or performance.

On January 10, 2002 a stakeholders teleconference was held to discuss the status of the project. It was agreed to suspend this project. The sole use for BR127 primer currently being used is for military application only, and BR6747-1 remains the only viable alternative available at this time, which is not acceptable to all stakeholders. In April 2003, due to insufficient funding and the fact that the environmental driver had been rescinded until FY05 the project was suspended indefinitely. Therefore, JG-PP recommends keeping this project as an Information Exchange Project.
