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.
Bonding:
The thickness of the layer depends on the expected mechanical movement. Join the material to be bonded within 45 minutes after application. Due to the low initial tack, we re commend mechanical fixing until a complete cure is obtained. The cure time is dependent on temperature, humidity and the dimensions of the joint. The absolut moisture content depends on the air temperature. Therefore, we recommend the use of our hardener Köracur 110. Körapur 940 Marine will cure unaffected by water when using hardener Köracur 110.
Cleaning:
- Körasolv PU
- Clean tools immediately after use.
- Once cured material can only be removed mechanically.
