Modified Epoxy Adhesives
Chemistry Overview
ForzaBuilt modified epoxy adhesives combine epoxy strength with improved peel, impact, and fatigue resistance for dynamic assemblies.
Modified epoxies are epoxy formulations enhanced with flexibilizers, rubber particles, or reactive tougheners to improve peel strength, impact resistance, and fatigue performance.
Production Challenges We Help Solve
- Brittle bond failures caused by impact, drop, or vibration in standard epoxy joints.
- Peel-prone configurations where classic epoxy can crack and propagate.
- Applications needing high tensile strength with a more ductile failure mode.
- Bonding flexible or semi-flexible substrates that stress-crack rigid epoxy.
Typical Use Cases
Performance Snapshot
| Performance Factor | Typical Range |
|---|---|
| Chemistry | Epoxy resin with rubber or urethane toughener and amine hardener |
| Cure Speed | 15 minutes to 24 hours |
| Tensile Strength | Up to 35 MPa with improved elongation |
| Temperature Range | -55 C to +150 C |
| Substrate Range | Metals, CFRP, GFRP, SMC, ABS, PC, wood |
| Key Improvement | Peel strength 2-5x higher versus standard epoxy |
