Emseal Chemseal
Short Description
Chemical-Resistant, Structural Expansion Joint and Construction Joint Sealant
A chemical resistant sealant and expansion joint, Chemseal is a precompressed, primary seal for retrofit and new structural expansion joints and construction joints where contact with harsh chemicals and chemical dilutions is expected.
The standard coating is a chemical-resistant silicone that is NSF compliant which also allows it to be installed in areas which are sensitive to food contamination. Chemseal can be manufactured with a polysulfide coating in place of the standard silicone seal. While polysulfide may offer a wider range of chemical resistance, it necessitates a more complicated installation procedure. Consult EMSEAL for applications involving a particular expected chemical exposure and head pressure.
NOTE: EMSEAL suggests the use of Submerseal for most submerged applications. Submerseal’s single bellows construction and increased silicone thickness makes it suited to accommodate the head-pressure of continuous submersion. When contact with extraordinary chemical compositions is expected, Chemseal may provide a suitable alternative. Consult EMSEAL.
