Disclosed are a water-expandable rubber composition and a water-expandable rubber pad including the same. The water-expandable rubber pad manufactured using the water-expandable rubber composition is rigid enough to be directly inserted into a cylinder jacket even without a metal plate, etc. Moreover, the water-expandable rubber pad may increase in volume upon contact with engine coolant, thereby being optimized for an assembly process and facilitating design. Thus, since no separate assembly parts are used compared to conventional cases, the number of parts can be reduced, and costs can be reduced, and adhesiveness of the rubber pad is superior to that of conventional foam rubber and thus heat retention performance is excellent, resulting in improved engine fuel efficiency.

The invention pertains to a composition based on a fluoroelastomer comprising nitrile or carboxylate-type cure sites and including a curing agent and a Br-containing marker having reactivity towards the said cure-sites, which can be cured so as to deliver cured parts maintaining chemically bound bromine atoms; this material, when submitted to wear/damage would hence release Br-containing contaminants, which can easily spotted via notably an on-line mass spectrometer, so as to monitor and anticipate critical failures of sealing materials based there upon.

The present invention is directed to a phosphated epoxy resin comprising at least one terminal group comprising a phosphorous atom covalently bonded to the re sin by a carbon-phosphorous bond or by a phosphoester linkage; and at least one carbamate functional group.
