Fine-L-Kote UR Urethane Conformal Coating
Description
Key Points:-
- Single-component urethane conformal coating manufactured by Techspray for PCB chemical, moisture, and abrasion protection.
- Cures to form a flexible dielectric barrier operating across a temperature range of -65°C to 125°C.
- Meets IPC-CC-830B and MIL-I-46058C industry standards for mission-critical electronics.
- Contains an integrated UV indicator dye that fluoresces under black light for automated optical inspection (AOI) verification.
- Offers high chemical and solvent resistance against fuel oils, hydraulic fluids, and corrosive atmospheres.
- Suitable for application via automated selective coating, dipping, or manual spray systems.
JEC Technology distributes Techspray Fine-L-Kote UR, a high-performance single-component urethane conformal coating formulated to shield printed circuit boards against harsh chemical environments, severe humidity, and mechanical abrasion. Forming a durable, flexible dielectric barrier upon curing, Fine-L-Kote UR prevents parasitic leakage currents, dendritic growth, and electrochemical corrosion across densely populated SMT assemblies.
Engineered for mission-critical automotive, industrial control, and aerospace electronics, this urethane polymer maintains excellent flexibility and structural integrity across wide thermal cycling ranges (-65°C to 125°C). Through JEC Technology’s distribution network in Singapore, manufacturers gain access to qualified moisture-barrier solutions that conform to stringent IPC-CC-830B and MIL-I-46058C standards.
Features
Fine-L-Kote UR contains an integrated UV indicator dye that fluoresces under black light, enabling automated optical inspection (AOI) equipment and technicians to rapidly verify complete, uniform coating coverage and film thickness. The cured film exhibits superior solvent and chemical resistance, repelling fuel oils, hydraulic fluids, and corrosive industrial atmospheres.
Formulated for versatile application, it can be applied via automated selective coating systems, dipping, or manual spray equipment with predictable viscosity and flow control. The resulting high-dielectric coating insulates traces against high-voltage arcing while accommodating thermal expansion differentials between board substrates and soldered components.
