Dymax 429‑GEL is a clear, structural bonding gel cured by UV/Visible light, engineered for bonding glass, metals, engineering plastics, and composites in optical and impact-resistant applications.
Features
- Ultra-fast UV/Visible cure, tack-free within seconds
- High-viscosity gel (~30,000 cP) for precise, non-sag dispensing in tight gaps
- Strong adhesion across glass, metals, plastics, glass, and composites
- Low shrinkage and high flexibility, minimizing joint stress
- One-part, solvent-free, environmentally safe and RoHS-compliant
- Optically clear cure, non-yellowing over time
- Technical Specifications
- Viscosity: ~30,000 cP
- Hardness (Shore D): ~60–70
- Tensile Strength: ~10–15 MPa
- Elongation at Break: ~150–200%
- Modulus: ~150–250 MPa
- Glass Transition Temperature (Tg): ~80–90 °C
