NWK 743 has 1000% elongation.
Elongation is measured by applying tensile force, or stretching the material in the same manner as described previously, and determining the change in length from original. Elongation is expressed as a percentage of the original length. Ultimate elongation is the percentage change in length from original to rupture.
NWK743 is Urethane component and shows 1000% elongation, excellent adhesion, waterproof.
That is, 1cm increases to 10cm.
