Chem-Shield (30 oz., black/black color)
Chem-Shield liners are constructed with interpolymer alloy coating that combines excellent durability with
resistance to many chemicals. This fabric is suitable for containment of oily water, sludge, transformer
mineral oil, sulphuric acid, PCB transformer oils, 30% chlorine, ammonium hydroxide, ethanol and
fertilizer. This liner is designed to contain most chemicals suitable to -20 F. Call SEI to confirm usage of a
specific chemical. Using optional corrosion proof fittings, phosphoric acid (10%) and sodium hydroxide
(60%) is also permissible.
An alternative glue for repairs would be Loctite 495, which should be available
locally.
Arctic-Shield (tan/green color, used in Arctic berms)
Arctic-Shield liners are constructed from urethane-coated nylon that meets U.S. military specification MIL-
T-52983G for fuel tanks. The following fluids are acceptable for containment: Jet A, Jet B, JP-1, JP-4, JP-
8, kerosene, avgas, diesel fuels with less than 40% aromatic content and isopropyl alcohol suitable to -50 F.
Arctic-Shield fabric is not suitable for use with gasoline (contact SEI for information on the Desert King).
Arctic-Shield fabric meets U.S. military specification MI-T-52983G and ATPD-2266.
An alternative glue
for repairs would be 3M(DP420), which should be available locally.
Arctic-Shield fabric will provide longer service life due to a higher resistance to abrasion. It can also be
used in warmer climates.
Chemically Resistant Insta-Berm System
Chemically resistant Insta-Berm systems are made from polymer coated polyester or nylon fabric. This
fabric combines excellent durability with resistance to many chemicals.
The data shown in the chart on the following page is the result of laboratory tests and is intended to serve
only as a guide. No performance warranty is intended or implied. The degree of chemical attack on any
material is governed by the length of time, temperature and size of the area exposed.
When considering chemically resistant Insta-Berm system for specific applications, a fabric sample should
be tested in as close to actual service conditions as possible.
Important Note
Please contact an SEI representative for information on which fluids are acceptable for
containment in a chemical resistant Insta-Berm system. The user is responsible for ensuring the
berm is suitable for each application.
