Sealing ventilation ducts
ADVANTAGES
▪ The fungicidal properties guarantee a
proven antibacterial inertia over a long
period.
▪ DLK is non-corrosive, and thus can be
used on aluminium, copper and zincplated
surfaces. This offers maximum
flexibility.
▪ Thanks to the high elasticity of 25%,
DLK is ideally suited to high-stress
expansion joints. This guarantees longlasting
sealing.
▪ DLK is low-odour and therefore ideal
for use in confined spaces.
