Fig07 RESEARCH ON ROOF-PAD PADS I am interested in any data dealing with the use of low permiability, expandable polyurethane foam (app 2 lbs/cu. ft. expanded density)as part of a corrosion protection system for deep recess (app 25')aluminum extrusions (6061-T6)to be used in tropical/marine environments. I have a tubular (rectangular, 50' long) extrusion with internal dimesions of 2" X 20". I want to apply a chromate conversion coating and foam the inside and paint the outside.. IMPORTANT: If you are in a position of helping me out with this specific question then donšt bother not to call.
