Frequently Asked Questions

Answers to the most frequently asked questions

Questions:

1. How is shelf life determined for the aerospace tapes?
2. What tests are run in determining whether the material is usable/good?

Answers:

1. How is shelf life determined for the aerospace tapes?
   Shelf life was determined by testing properties, peel adhesion, cone penetration, yield strength, and vacuum bag seal of the tape monthly from when it was manufactured until failure. The tape must pass the vacuum cycle and stay within acceptable limits for remaining properties.
2. What tests are run in determining whether the material is usable/good?
   We typically test the cone penetration (ASTM D 217), peel adhesion (AAMA 800), yield strength (ASTM C 908), and an in-house vacuum bag test.
