Electrical Insulation
Usage Guide
Electronic silicones provide reliable insulation, protection, and thermal management when applied to clean, prepared substrates. Correct application ensures component longevity and performance.
Surface Preparation
Ensure surfaces are free of dust, oil, and moisture. Mask sensitive areas if necessary.
Application
UV-Curable Coating: Apply thin uniform layer; cure under specified UV intensity.
Potting Compound: Mix if required; pour to cover components; avoid bubbles.
Sealant: Apply evenly around connectors, housings, or joints.
Curing
UV coating: surface cure in minutes; full cure depends on thickness.
Room-temperature or heat-cured grades: tack-free in 30–60 min, fully cured in 24–72 hours depending on thickness.
Key precautions for this type of product
- Avoid curing in completely enclosed, UV-blocked areas (for UV grade).
- Ensure substrates are dry for optimal adhesion.
- Follow thermal management specifications for heat-sensitive components.
