Adhesive sealant for vapour-proof barriers
COSMO® DS-420.240
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
