KM-4040M ADEKA ULTRA SEAL

GENERAL DESCRIPTION
KM-4040M is a chemically modified natural rubber product
with an embedded stainless steel wire mesh. A patented
process chemically binds a hydrophilic agent to the rubber.
The hydrophilic agent causes KM-4040M to undergo
controlled expansion in the presence of moisture. This
expansion capability provides a "double locking" waterstop.
KM-4040M stops water by compression from rubber's natural
resilience and by moisture induced expansion. When
hydrated, KM-4040M will fill any void within the limits of its
expansion capability (150% by volume). KM-4040M is a
vulcanized product. Since it is cross linked with sulphur in the
vulcanization process, it has high tensile and compressive
strength plus good restorability.
KM-4040M has excellent durability and resistance to
chemicals. It can perform in a wide range of solutions such as
salt or cement water. KM-4040M is environmentally safe. It
does not contain any toxic substance or heavy metals.
BASIC USE:
