Miller-Stephenson Chemical MS-470C Urethane Conformal Coatings
- Chemical Family
- Polyurethanes (PU)
Miller-Stephenson Chemical MS-470C Urethane Conformal Coatings is a non-flammable, solvent-based, one-component polyurethane conformal coating provided in the convenience of aerosol. Our coating provides excellent electrical and barrier properties in a thinfilm applications on components and PCBs. When fully cured, the applied urethane coating exhibits superior toughness, abrasion resistance, and excellent moisture and chemical resistance. MS-470C will maintain its properties even after long exposure to the elements with minimal color change.
