Acrylic Conformal Coating for PCB
What is acrylic conformal coating for PCB?
Acrylic conformal coating is a protective material applied to printed circuit boards (PCBs) to shield them from environmental factors like moisture, dust, chemicals, and temperature changes. It is made from acrylic polymers dissolved in a solvent, forming a clear and durable layer once cured.
N-PU 5200H is a midium-high viscosity, one-component, UV curing conformal coating specially designed for protecting circuit boards. It has high viscosity, is economical and environmentally friendly, can spray thicker films, and is suitable for various spraying processes. N-PU 5200H has excellent protective effects.
