Pro-Series SBR-100 window and siding caulk

OSI Sealants' Pro-Series SBR-100 window and siding caulk is formulated for year-round use, extruding consistently and easily from 0 to 100 degrees F. When cured, the rubber base forms a tight seal that maintains its bond under most weather conditions. Designed primarily for the aluminum siding industry to eliminate the problems of extrusion, cut-off, stringing and dirt collection commonly found in oil-based and butyl caulking compounds, SBR-100 goes on easily and needs no tooling when applied as directed.
