ADVANTAGES
▪ Thanks to the high elasticity of 25%,
DDK is ideally suited to high-stress
expansion joints. This guarantees longlasting
jointing.
▪ DDK holds without a base coat,
including on moist and bituminous
substrates, and is therefore suitable for
all applications in the roofing area. For
a high degree of economy.
▪ The immediate rain resistance allows
for external application in all weather
conditions, thus avoiding interruption
of work.
▪ DDK is non-corrosive, and thus can be
used on aluminium, copper and zincplated
surfaces. This offers maximum
flexibility.
