Processing

Processing temperature: +5°C to +35°C

Preparation:

  • The surfaces to be bonded must be clean, dry and free from dust and grease. For cleaning we recommend Körasolv PU. In the case of powder coated substrates, Körasolv WL should be used.
  • To increase bond strength of non-porous substrates such as glass, glass-fiber reinforced plastics, gel coat, aluminum, stainless steel, etc. we recommend the use of Körabond HG 81. For porous substrates such as wood, Körabond HG 74 E is recommended. For certain plastics such as ABS or PVC we suggest the use of Körabond HG 77.
  • Due to the diversity of substrates, preliminary tests are necessary.

Bonding:

The thickness of the layer depends on the expected mechanical movement. Join the materials to be bonded within the skin formation time. We recommend mechanical fixing until a complete cure is obtained. The curing time depends on temperature, humidity and the dimensions of the joint. When necessary, the curing can be improved by water spraying. This may be required in winter.
