HENSOMASTIK® K 2000 special adhesive

HENSOMASTIK® K 2000 is a flexible special adhesive. It bonds fire-protection boards with additional mechanical fixing, serves as an installation aid when working with insulating materials and assists when bonding and sealing fire-protection boards for the construction of ventilation systems.

Its high degree of elasticity makes it suitable for joining materials with very different coefficients of thermal expansion, as well. HENSOMASTIK® K 2000 is therefore used in the construction of railway carriages to fix insulating material between exterior sheet metal panels and interior cladding, for example.

Use

• Incombustible adhesive joints
• Bonding of building materials with different coefficients of expansion

(e.g. fixation of isolation/insulation material between the inner and

outer walls in wagon construction)
• Bonding of fireproof boards to concrete or aerated concrete with

additional mechanical fastening
• Fixing and sealing of fireproof boards for ventilation ducts • Installation aid for the processing of insulation materials

Properties

• Building material classification A2 (non combustible) • Solvent-free
• Organic
• Colourless

• Permanent elastic (does not become brittle)
• Ready for spraying or viscous material available

Application

• The adhesive has to be stirred thouroughly before use
• Surfaces shall be free from any contamination!
• Temperature during application and drying > + 5 °C
• Substrate temperature should be at least + 3 °C above dew point

and in any case above 0 °C! •Workabilitytimeat+20°Cambienttemperature andarelative

humidity of 65 % = 15 minutes
• If materials of different densities should be glueed, the adhesive

must be applied onto the material with the higher density
• Coverage rate depends on the structure of the material surfaces

and purpose: 0.1 to 1.5 kg/m2
• Before joining parts, especially overhead or vertically, an 8 to

20 minutes interval of airing is recommended to guarantee an

instant fixing, bonding of parts under pressure
• Clean working tools and spraying machines if work is interrupted for more than 20 minutes immediately with water or pump ­HENSOMASTIK®­K­2000 "in the circle"
