Pre-mixed frozen aircraft sealants

  • 13-Nov-2013 01:51 EST


Graco Supply now offers extended shelf-life options on pre-mixed frozen sealants for aircraft applications. As an authorized packaging distributor for the Royal Adhesives and Sealants product line, and a NADCAP-accredited packaging site, Graco’s location in Georgia conducted specification-required Final Acceptance Testing on the frozen sealant products. Testing revealed that the application properties of the products maintained at -40ºF for up to 90 days were unaffected (tack free, application time, and cure time). The products tested include those certified to AMS-S-8802, AMS-3281, AMS-3284, and Mil-PRF-81733. While the various specifications require a minimum shelf life of 30 days when stored at -40ºF, these products were verified to be well within specification application requirements for as long as 90 days from the date of mix/freeze.
