Miller-Stephenson Chemical MS-472C Urethane Coating
- Chemical Family
- Polyurethanes (PU)
Miller-Stephenson Chemical MS-472C Urethane Coating is a non-flammable, solvent-based, one-component polyurethane conformal coating that be applied by brush, spray or dip methods. Our coating provides excellent electrical and barrier properties in a thin-film applications on components and PCBs. When fully cured, the applied urethane coating exhibits superior toughness, abrasion resistance, and excellent moisture and chemical resistance. MS-472C will maintain its properties even after long exposure to the elements with minimal color change.
