Construction sealant Premium DKM

The universal hybrid sealant and adhesive for interior and exterior use

The fischer construction sealant Premium DKM is approved for the permanently elastic sealing of connection and movement joints inside and outside and for the sealing of window and door connection joints. Its resistance to mould also enables use in sanitary applications. Testing as per DIN EN ISO 846 means that use as a ventilation duct sealant is also allowed. Due to its high resistance to mechanical stress, the fischer DKM is also ideal for sealing floor joints. Its additional usability as an elastic adhesive with a high initial adhesion to a variety of substrates - which can also be moist - makes the fischer DKM into a universal sealant adhesive. Its crystal clear property allows for unobtrusive sealing and glueing inside in cases where invisible joins are particularly important.

Product Description

  • Due to the high elasticity of 25%, the DKM is ideal for particularly stressed joints, and ensures lasting sealing.
  • The high initial adhesion rate of up to 75 kg/m² (50 kg/m² in the crystal clear version) enables the attachment of multiple components without additional fixing, thus reducing time requirements.
  • The fungicidal properties guarantee a proven antibacterial inertia over a long period.
  • DKM is low-odour and therefore ideal for use in confined spaces.
