Features and Specifications

DOWSIL 3 1965 Conformal Coating – One part, transparent, solventless conformal coating meeting UL, IPC, and Mil Spec standards.

DOWSIL 3 1965 Conformal Coating is a one part, transparent, solventless, low viscosity coating designed for protecting sensitive electronic components. It cures at room temperature into a soft, low stress elastomer, offering excellent flexibility and stress relief. The inclusion of a UV indicator simplifies inspection, ensuring complete coverage of the protected surfaces. Its low viscosity allows for excellent flow and fill, even in tight spaces, enhancing protection against environmental factors and mechanical stress.

The coating adheres well to a variety of substrates, including low solids and no lead solders, contributing to improved reliability. While suitable for use on rigid and flexible circuit boards and printed wiring boards (PWBs), proper surface preparation may be necessary on low surface energy materials to optimize adhesion. Cure time is variable and depends on factors such as film thickness, temperature, and humidity; however, mild heat (60°C or less) can accelerate the curing process. Proper ventilation is crucial when using solvents or stripping agents for repairs.

Key Features:
