U Prime 274 685SP

The 274 685SP/274 686SP U-Prime system is a two-component urethane primer with rust inhibitors for use on aluminum or steel. U-Prime is white in color which makes this a dual purpose product. An entire sign can be primed white with only the exterior surfaces requiring a Matthews Acrylic Polyurethane topcoat. When mixed according to directions, U-Prime will comply with emissions requiring a VOC level of 2.8 lbs./gal to 3.5 lbs./gal. It has good adhesion to properly prepared and cleaned aluminum or steel and provides an excellent base for all MAP® topcoats.
