Dymax 4‑20418 GEL is a clear UV/Visible light-curable gel adhesive designed for precision bonding of small components, plastic frames, and glass in applications requiring high accuracy and aesthetic quality.
Key Features
- Fast curing under UV/Visible light, achieving tack-free surface within seconds.
- High-viscosity gel (approximately 25,000–45,000 cP) for accurate dispensing with no flow.
- Excellent adhesion to engineering plastics, glass, metals, and electronic components.
- Low shrinkage and high flexibility minimize stress on bonded parts.
- One-part, solvent-free formulation that is environmentally friendly and RoHS compliant.
- Optically clear and non-yellowing over time, suitable for visually critical applications.
