KM-STRING ADEKA ULTRA SEAL

product. A patented process chemically binds a
hydrophilic agent to the rubber. This permits the KM
String to undergo controlled expansion when in the
presence of moisture. This expansion capability
provides a "double locking" waterstop. One from
rubber's natural resilience and one from the
expansion. Any void, within the limits of the
product's volume expansion coefficient, will be filled
by the expansion of the KM when it is hydrated.
Expansion occurs in all dimensions, diameter and
length. Expansion will follow the direction of least
resistance. The Volume Expansion Coefficient of 3
times indicates the material will increase 3 times by
volume, not 3 times in size. Linear expansion
coefficient is approximately 1.45.
