739 BrushSeal Water Based Elastomeric

739 BrushSeal Coating is an economical but effective vapor-barrier coating for use over all types of thermal insulation. It is most suited for insulated systems which are operating below ambient temperature but not below 32 degrees Fahrenheit, such as chilled water lines, air conditioning ducts, or other pipes or vessels within these temperature parameters. Colder systems than the above should be protected with Vimasco 749 VaporBlok which has a lower perm rating and is designed for heavy-duty applications.
