ECCOSORB^® CERSEAL is a factory applied vinyl based coating used to seal microwave absorbers in the ECCOSORB^® AN, LS and QR-13AF product lines.  CERSEAL is a superior low cost alternative to the neoprene-coated fabric used on ECCOSORB^® ANW and is UL 94HB flammability rated on UL 94 HF-1 foam.  CERSEAL is also sold as a liquid in quart cans for the patching of factory applied CERSEALED parts. 

CERSEAL is a tough coating that adds durability to foam and imparts abrasion and puncture resistance.  When applied, CERSEAL creates a barrier to moisture and chemicals and has excellent resistance to fluids and petroleum products.
