Polyurethane coating 2104
Polyurethane coating 2104 has good properties of moisture-proof, wear-resistant and chemical corrosion-resistant. It is widely used in all kinds of harsh chemical environment. The hard coating has a very good protective effect on circuit board. In addition, the polyurethane coating 2104 contains an external fluorescent agent, which is convenient for the quality control of the coating coverage area and thickness uniformity on the circuit board. The coating can be tested by standard and low-cost ultraviolet lamp (short wave black lamp). The thicker the coating is, the higher the luminous brightness is.
