Why 212k Outperforms Standard Assembly Adhesives
Fast Strength Without Cure Delays
Unlike moisture-cure systems, 212k cures independently, so you get consistent, predictable performance and faster throughput.
High Elongation That Prevents Failures
With ~464% elongation, this elastomeric adhesive flexes with movement, vibration, and thermal expansion—reducing cracks, bond failure, and callbacks.
Built for Multi-Material Bonding
Bond metal, glass, wood, fiberglass, and more with one adhesive to simplify your process and reduce SKU complexity.
Non-Sag Performance for Vertical Assembly
Stay exactly where you apply it. Ideal for panel bonding and vertical applications without slump or mess.
Built for Harsh Environments
Performs in demanding conditions with resistance to temperature swings (-65°F to 250°F), moisture, and environmental exposure.
Key Performance Data:
- Elongation: 464%
- Peel Strength (Aluminum): ~47.6 pli
- Tensile Strength: ~221 psi
- Mix Ratio: 1:1
- Working Time: Moderate (~22 min skin time)
- Service Temperature: -65°F to 250°F
(All values based on typical test data)
