About this product
838 MS is a hybrid moisture cure elastomer sealant designed to seal the seams and fasteners of metal roofs. This hybrid technology is 100% solids and isocyanate free. It has less moisture sensitivity than standard polyurethanes and maintains excellent physical properties (tensile strength and elongation). 838 MS is designed to encapsulate seams and fastener heads on metal roofs with minimal sag. Additionally, it can be used to seal gutters and penetrations (750 ml re-sealable pouches work well in these applications). 838 MS is typically poured or extruded onto the roof and then brushed into place. A consistent sealant thickness minimum of 50 mils is required. Do not apply if air temperature is below 42°F or substrate temperature is above 120°F.
