Cable grommets for subsequent installation

 

Advantages

  • Easily create secure seals around cables that are already in place
  • Extremely flexible and elastic
  • Quick and easy installation
  • Waterproof, also suitable for penetrations in façades and roof linings
  • Airtight bonds according to DIN 4108-7, SIA 180 and OENORM B 8110-2
  • Lowest VOC rating in hazardous substance test
 

Application

The sealing grommets, pro clima KAFLEX post, are used for the quick and long-term, secure airtight installation of pre-installed cables in accordance with DIN 4108-7. As a result of the waterproof adhesive and carrier materials, KAFLEX post is also suitable for outdoor use (e.g. windproofing in the roof lining and façade).

General conditions

The bonds should not be subjected to tensile strain.
Press firmly to secure the adhesive tape. Ensure there is sufficient back-pressure.
Windproof, airtight or rainproof seals can only be achieved on vapour retarding membranes, roof lining membranes or façade membranes that have been laid without folds or creases.
Ventilate regularly to prevent build-up of excessive humidity and use a dryer if necessary.

Substrate

Before sticking, subsurfaces should be brushed off, wiped clean with a cloth or cleaned using compressed air.
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 have sufficient load-bearing capacity.

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).
Adhesion and joints can be carried out on planed and painted wood, hard plastics and metal (e.g. pipes, windows etc.), hard wood-based panels (chipboard, OSB and plywood panels, MDF board and softwood fibre sub-roof panels).
Wood fibre sub-roof panels and smooth mineral subsurfaces require pre-treatment with TESCON PRIMER before bonding. 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 load-bearing capacity.
