PUS3101 Fast drying Polyurethane Conformal Coating
PUS3101 is a low-viscosity neutral polymer composite material, one-component, easy to spray, dip, and brush for conformal coating application. It has good high and low temperature resistance; After curing, PUS3101 forms a transparent protective film, which has excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, anti-corrosion, anti-aging, corona resistance, and other properties. Widely used in the surface coating protection of electronic components.
PUS3101 has a modified polyurethane chemical base and is free of silicone, ketone, phenol, and other materials, blue under UV light, and easy to detect.
Features and benefits
- Polyurethane conformal coating (free silicone coating)
- Fast drying time – 3 ~ 10 mins at room temperature
- Transparent protective layer
