Mois­ture ad­hes­ive seal­ing tape

 

Advantages

  • Pro­tects struc­tur­al ele­ments from wa­ter in­gress: wa­ter­tight and blocks rising damp
  • Cre­ates a se­cure bond: butyl rub­ber pen­et­rates deep in­to the sub­strate
  • Very elast­ic car­ri­er foil with par­tic­u­larly low restor­ing forces: it can be flex­ibly ad­ap­ted to sur­faces and corners
  • Bonds to min­er­al sub­strates
  • Air­tight bonds ac­cord­ing to DIN 4108-7, SIA 180 and OENORM B 8110-2
  • Low­est VOC rat­ing in haz­ard­ous sub­stance test
 

Application

Mois­turetight bar­ri­er tape to seal un­der sills in tim­ber struc­tures, for join­ing wood-based pan­els to smooth min­er­al sur­faces, to stick sub-roof pan­els one be­low the oth­er (e.g. in grooves and trans­itions) and to bond these to ad­join­ing struc­tur­al ele­ments.

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.

Per­man­ent ad­he­sion is achieved on wood­based pan­els (chip­board, OSB and ven­eer ply­wood, MDF board and wood fibre sub-roof pan­els).
Wood fibre sub-roof pan­els and smooth min­er­al sub­sur­faces re­quire pre-treat­ment with TESCON PRIMER RP 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 RP is re­com­men­ded in the case of sub­sur­faces with in­suf­fi­cient load-bear­ing ca­pa­city.

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.
To work with the tape, temperatures must be >5 °C during the day and night. If the initial bond is not satisfactory, a solvent (e.g. white spirits) may be applied to the grey butyl rubber side of the tape. The solvent increases the adhesiveness of the butyl rubber at low temperatures.
The tape is self-bonding under the effect of heat.
