Features & Benefits

Product Characteristics
  • Good adhesion to glass, many kinds of metal (zinc, aluminium, steel) varnished and primed surfaces. Bonds well to wooden materials, duroplastics and thermoplastics (except PE, PP, PTFE) and mineral surfaces
  • Usable for bonding of mineral glass in the ship and boat building industry
  • Good resistance to humidity, weathering and to temperatures from -40°C to +90°C (for short intervals up to +120°C)
  • Overpaintable in the wet-on-wet process

Processing Information

Processing temperature

  • +5°C to +30°C


  • Surfaces have to be dry, clean and free from dust and grease. To increase bond strength of absorbent materials such as wood we recommend the use of Körabond HG 74 E. Adhesion on non-absorbent surfaces can be increased by using Körabond HG 83. When bonding of mineral glass the glass panes must be pretreated with black primer Körabond HG 17. Preliminary tests are required.


  • Apply Körapop 954 Marine to the surface by using an appropriate application gun. Join the material within 5 minutes after application and press firmly together. The thickness of the layer depends on the expected movement of the joint. We recommend mechanical fixing until complete cure is obtained. The cure time depends on thickness of the layer, temperature and moisture.


  • The paint must be tested for compatibility by carrying out preliminary trails. The hardness and film thickness of the paint may impair air humidity. Thus, the curing reaction of the bond proceeds slower. The movement is determined by the characteristics of the film thickness.


  • Körasolv CR, GL or Körasolv PU. Clean tools immediately after use. Once cured, the material can only be removed mechanically.
