Cera Foam®

Our water-based, paintable coating with “chemical direct foaming” expands to 2.5 times its size to form adherent, porous, black foam when first heated up to 700 C. Cera Foam provides highly porous thermal insulation as well as sealing/filling holes and gaps or deteriorated surfaces. Usable to 800 C after foaming on all refractories and atmospheres, Cera Foam is so unique it is “Patent Pending”.
