1K PU Conformal Coating


Polyurethane Conformal coating for printed circuit boards. A single component, low viscosity, solvent based elastomeric polyurethane coating that insulates and waterproofs electrical equipment.

The high transparency allows clear visualisation of the surface below. It is an excellent insulator on PC boards since it allows visualization of circuit paths.

Intended Uses


1K PU Conformal Coating is designed to protect and insulate printed circuit boards. It will protect printed circuit boards from caustic or humid inorganic acid vapours & help prevent any electrical leakages or short circuiting.

1K PU Conformal Coating can withstand continuous temperatures up to 100°C & intermittent temperature surges up to 150°C.

Used as an extra/after insulation coating on coils & transformers, motor windings, terminal, bus bars, commutator ends, stator coils and PC Boards
