Cable grommets for retrofit installation, for interior and exterior use

KAFLEX post

Advantages

  • Keeps building components dry: practical joints to already installed cables
  • Easy to work with: extremely flexible and elastic
  • Reliable joints thanks to waterproof SOLID adhesive
  • Construction in adherence with standards: for airtight bonding in accordance with DIN 4108-7, SIA 180 and RT 2012
  • 3 months of outdoor exposure
  • Excellent values in the hazardous substance test, has been tested according to the ISO 16000 evaluation scheme

Areas of Application

For quick, permanently secure sealing of previously installed cables and conduits up to 20 mm in the interior airtightness layer. As a result of its waterproof adhesive and substrate materials, KAFLEX post is also suitable for exterior use (e.g. windtightness in underlay and facade area).

Installation instructions

General conditions

The bonds should not be subjected to tensile strain.
Press firmly to secure the adhesive tapes in place. Ensure that there is sufficient resistance pressure.
Windproof, airtight or rainproof bonding can only be achieved on vapour retarders, roof underlays or wall lining membranes that have been laid without folds or creases.
Ventilate continuously and systematically to prevent build-up of excessive humidity; use a dryer if necessary.

Substrate

Clean subsurfaces before sticking.
Adhesion to frozen surfaces is not possible. There must be no water-repellent substances (e.g. grease or silicone) on materials to be bonded. Subsurfaces must be sufficiently dry and stable.

Install the cables without strain, fix cables with a cable clip as required.

A permanent bond is achieved on all pro clima indoor and outdoor membranes, other vapour retarder and airtightness membranes (e.g. PE, PA, PP and aluminium foil) as well as roof and wall lining membranes (e.g. PP and PET).
Bonding and joints are possible on planed and painted wood, hard plastics and metal (e.g. pipes, windows etc.), hard wood-based panels (chipboard, OSB, plywood, MDF and wood fibre underlay panels).
Pretreatment with TESCON PRIMER is required in the case of adhesion to wood-fibre underlay panels and smooth mineral subsurfaces. Concrete or plaster subsurfaces must not be sandy or crumbling.

The best results in terms of structural stability are achieved on high-quality subsurfaces.
It is your responsibility to check the suitability of the subsurface; adhesion tests are recommended in certain cases.
Pretreatment with TESCON PRIMER is recommended in the case of subsurfaces with insufficient stability.
