Description

Air-tight bonding of vapour checks and barriers as well as sealing films. Immediately in view: Indicator for hardening state of the mass!   APPLICATION EXAMPLES • For permanently elastic, airtight bonding of joints, structural connections and overlaps, sealing of diffusion barriers, vapour-proof barriers and sealing films in dry construction (except swimming pools) in accordance with the Buildings Energy Act (GEG). • Bonding/Sealing of diffusion-tight and moisture diffusing seal tapes with window and door assembly.   SPECIAL CHARACTERISTICS • Very low emission* • Colour changes by hardening • Permanently elastic self-adherent adhesive joint • Thixotropic, does not drop off • Joint filling • Solvent-free • Freeze-resistant • Very high initial adhesion • Fast functional strength • Can be used without contact pressure lath in accordance with DIN 4108-7 (2011-01) for joints and connections with new building and refurbishment measures. • It meets the requirements as per DIN 4108-11 • Excellent adhesion to the most varying building materials (stone, concrete, plaster, floor screed, dry lining boards, wood and diverse metals) as well as to the films in question • Achieves the required air-tight connections/final sealings of building envelops • Bonding of films, window joint tapes, on slightly humid, dusty and absorbent substrates • Accelerated curing behaviour on non-absorbent substrates • high adhesive strength after complete curing time • no corrosion caused on metals
