PU1030-NF is one-component and fast air-drying conformal coating material based on modified polyurethane resin. PU1030-NF is non-hazardous chemical (GB / T261-2008) which flash point (closed cup) is higher than 61 ℃ ,so it can be stored and transported as non-hazardous chemicals. Any aromatic solvents, such as xylene, toluene is not concluded in the varnish. The cured coating film has a good performance in temperature resistance, humidity-heat tolerance, salt endurance and excellent adhesion. PU1030-NF can be applied in different insulating and anti-corrosion area for PCBA protection.
