Expand-A-Seal ES0105®
Expand-A-Seal ES0105 is a unique microencapsulated expanding threadlocking and sealing compound. Expand-A-Seal increases in volume 20 to 50% on installation, penetrating the gaps in fastener threads that are typically unfilled by conventional threadlockers.
How Expand-A-Seal Works:
- Install an Expand-A-Seal-coated fastener into its mating part.
- The installation pressure causes the Encapsulated Epoxy Resin and Expanding Capsules to burst and mix with the Epoxy Hardener.
- A chemical reaction makes the Epoxy expand, filling the fastener thread gaps while hardening.
- The fastener is fixed in place within 10-15 minutes. Full cure is achieved in 24 hours.
Fastener variation can create gaps (shown in white) between mating surface threads. Conventional threadlockers (blue area) are thin and insufficient at filling these spaces.
Expand-A-Seal (green area) expands 20 to 50%, completely filling the gaps between fastener threads, resulting in a strong lock and high-pressure seal.
Applications:
Use Expand-A-Seal ES0105 to seal critical applications where shock, vibration and fluid pressure cause the fastener to loosen or the joint to leak. Typical applications include:- Engine pipe plugs
- Air fitting connectors
- Compressor fittings
- Cooling connectors
- Marine ride plates
