Dymax Multi‑Cure 9‑20558‑REV‑A is a high-viscosity, flexible encapsulant/conformal coating designed for UV + heat dual-curing—ideal for protecting electronic components in shadowed areas. It delivers strong adhesion, flexibility, and environmental resistance.
Key Features
- Dual-cure system: UV/Visible light rapidly creates a tack-free surface; heat cure (110–150 °C) completes cure in shadow regions.
- Thixotropic, high-viscosity formulation: Ideal for coating tall or densely populated components without slumping.
- Flexible and resilient: Minimizes mechanical stress; compatible with flexible circuits (FPC).
- One-part, solvent-free: Easy to process; halogen-free; RoHS compliant; UL 94 V‑0 flame rating.
- Excellent substrate adhesion: Bonding to FR4, metals, ceramics, epoxy-fibers.
