Operational Gap: Lack of environmentally friendly adhesives that could meet performance requirements.
Cements used to bond rubber to metal and rubber to rubber contain large amounts of hazardous volatile organic compounds (VOCs), including methyl ethyl ketone (MEK), toluene, and methyl isobutyl ketone (MIBK). These adhesives are essential to the bonding of gaskets, door seals, bumpers, heater boots, and other applications during Naval Aircraft maintenance and assembly operations. Environmental laws and regulations require the development of new non-hazardous cements that meet or exceed the performance requirements of MMM-A-121, MMM-A-122, and MMM-A-1617. Texas Research Institute Austin, Inc. has developed and tested a new environmentally compliant, high performance cements. This cement is available from W.W. Henry.
