  1. Product Overview
    DOWSIL™ 1-2620 Dispersion RTV Elastoplastic Conformal Coating is a one-part, transparent, low-viscosity silicone resin solution designed for printed circuit board protection. It cures at room temperature with optional mild heat acceleration after solvent flash-off. The coating provides a tough, abrasion-resistant surface with good adhesion to many substrates, UV indicator for inspection, and compliance with UL V-0 flammability and Mil Spec 46058C standards. It is suitable for electronic applications requiring dielectric protection, environmental resistance, and repairability.
  2. Applications
  • Protective coating for rigid and flexible circuit boards
  • Ideal for printed circuit board (PCB) assemblies
  • Provides abrasion resistance and dielectric insulation in electronic systems
