Product Description

 

Nelson Compound (CMP™) is a cementitious material that is mixed with water. It is similar in appearance to mortar and can be troweled to a smooth finish that provides a weather resistant, non-shrinking fire-rated seal.

Application

CMP™ has been tested for a wide range of penetrants including metallic pipes, cables, cable trays, as well as combustible penetrants such as insulated pipes. It is ideally suited for medium to large openings filled with or without penetrants.
