All adhesives tend to lose strength on immersion in water. Water acts in two ways on a bonded assembly: It can be absorbed into the adhesive and soften it, and it can degrade the interface between the adhesive and the bonded surfaces.
HyPox RA875 reportedly enables improved peel strength at room temperature and temperatures down to -40°C, as well as enhanced adhesion to oily substrates when compared to core-shell rubber (CSR).

Liquid polysulfide polymers are aliphatic resins that provide beneficial chemical resistivity, weatherability, gasoline and jet fuel resistance, and gas barrier properties, as well as easy processability. In the cured state, these polysulfides feature plasto-elastomeric properties in which polysulfides can undergo self-healing.
The one-part epoxy can reportedly be activated by UV or blue light from 365-405 nm with an intensity of about 150 mW/cm2 for 5-10 sec.
