Terokal TK 395

Single component polyurethane foam, specially developed for the adhesion of insulation materials in flat roofing such as: polystyrene (PS), hard foam, insulation boards, etc. Terokal TK 395 can be bonded to both absorbent and non-absorbent substrates, such as concrete, timber, brickwork and profiled metal, as well as onto aged bitumen, asphalt or even mineral topped felts which are still firmly attached.


  • Efficient and economical.
  • Levels off uneven substrates.
  • Reliable holding power.
  • Short curing time.
  • Works in cold weather (as low as -5 degrees C).


  • Suitable for bonding thermal insulating products on flat roofs such as:
  • Mineral fibre insulation materials.
  • Rigid phenolic resin (PF) foam.
  • Rigid polystyrene (PS) foam (boards, roll-on membranes, folding membranes).
  • Rigid polyurethane (PUR) foam.
