REPURPOSED AEROSPACE MATERIALS wants to prevent short shelf-life, high value aerospace materials from going to waste.
Up for grabs is an expired kit (DOE: 11/30/23 - for use on aircraft) of 3M Scotch-Weld EC-3524 void filling compound. 3M Scotch-Weld Void Filling and Edge Sealing Compound EC-3524 B/A is primarily used in aerospace applications for void filling, edge sealing, and abradable applications in aircraft engines. It's a two-part, flame-retardant epoxy that can also be used for reinforcing honeycomb structures and bonding inserts.
Here's a more detailed breakdown of its uses:
-
Void Filling:EC-3524 B/A is used to fill voids in composite structures, ensuring a smooth, flush surface.
-
Edge Sealing:It seals the edges of honeycomb sandwich structures, providing protection and improving structural integrity.
-
Reinforcing Honeycomb:It reinforces honeycomb structures, improving their strength and impact resistance.
-
Bonding Inserts:It can be used to bond various inserts into composite structures.
-
Fairing Compound:EC-3524 B/A can be used as a fairing compound to achieve aerodynamic flushness.
-
Other Uses:
- Potting and Complex Gap Filling: It can be used for potting applications and filling complex gaps.
- Flame Retardant: Meets fire retardancy requirements for aerospace applications.
- Non-Sag: Its non-sagging property allows for easy application to multiple workpieces at once.
- Paintable: Can be painted after curing, allowing for a smooth, finished surface.
- Sandable: Sandable within 3 hours of mixing.
- Strong, Low-Density Material: Provides impact resistance and saves weight.
- Extended Worklife: Provides ample time for application and positioning of parts.
Due to aerospace shelf life restrictions, this material has expired for aerospace use yet still has tremendous value. Whether it be for automotive or RV repair, hobbyist work, or artists doing artist things, we are happy to see these landfill bound materials, help you realize their high value and a fraction of the original cost.
