406 - Rhino/CoverCat 406

Rhino/CoverCat™ 406 is a spray in place pipe lining for use exclusively with Covercat Plural Component Spray Equipment. It is a highly versatile formulation designed for use in a wide variety of applications ranging from potable water relining, to highly demanding chemical environment coatings such as gas and oil processing.



Rhino/CoverCat 406 has excellent heat resistance properties allowing its use in elevated temperature environments. It also superior adhesion to damp substrates such as iron, steel, clay, and cementitious pipe or similar conveyances requiring coating and rehabilitation.

Applications are tack free within 2-3 hours and may be immediately recoated to achieve additional coats of up to 20 mils to repair cracks or fill defects. Pipes lined with the Rhino/CoverCat 406 are returned to service within 24 hours, and will cure underwater providing an exceptionally fast pipe placement and service turnaround. Rhino/CoverCat 406 meets NSF 61 standards and fulfills other demanding and time critical application requirements.
