Series 434 | Perma-Shield H2S

Generic Type Modified Aliphatic Amine Epoxy Mortar
Common Usage A 100% solids, hybrid epoxy mortar designed for severe wastewater immersion and fume environments. Specifically formulated to withstand high levels of hydrogen sulfide gas (H2S), sulfuric acid (H2SO4), as well as other gases common to sewer exposures. Aggregate reinforcement provides additional resistance to abrasions and impacts.
