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
