Harmonization Code : 3214.10.00 | Putty and other mastics | Resin cements, caulking compounds and other mastics

Main features
- Clear Two-Part Epoxy Bondline
- 5-10 Minute Handling Strength
- 4 mm Gap Filling
Product Description
Permabond ET502 is a colorless two-part epoxy adhesive for general-purpose bonding where a clear bondline and room-temperature cure are required. The 1:1 system has a mixed viscosity of 45,000-90,000 mPa s at 25 deg C, fills gaps up to 4 mm, and provides a 3-5 minute pot life at 23 deg C. Handling strength is reached in 5-10 minutes, with full cure after 24 hours at 23 deg C. Applications include wood, metals, ceramics, selected plastics, and composites.
Key features
- Clear Bondline: Colorless components cure to a clear epoxy bondline.
- Rapid Handling: Reaches handling strength in 5-10 minutes at 23 deg C.
- 4 mm Gap Fill: Fills bond gaps up to 4 mm with a 1:1 mix ratio.
Applications
Applications include general-purpose bonding of wood, metals, ceramics, selected plastics, and composites where a clear bondline is required.
