Preparation
- 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.
Bonding
- 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.
Overpainting
- 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.
Cleaning
- Körasolv CR, GL or Körasolv PU. Clean tools immediately after use. Once cured, the material can only be removed mechanically.
- Processing Information
-
Preparation
- For some substrates the use of mechanical pretreatment and/or cleaner or primer is necessary to achieve good adhesion. Refer to the product properties section of this data sheet for special surface requirements and suitable adhesion promoters.
Processing
- Refer to the technical data table regarding processing parameters. Low temperatures can cause a temporary increase in viscosity resulting in reduced extrusion and slower curing rates.
Cleaning
- Clean tools immediately after use. Once cured, the material can only be removed mechanically. Appropriate cleaners are listed in the product properties table.
Dimensioning
- The required thickness of the adhesive layer depends on the expected maximum strength and joint movement. We recommend a minimum layer thickness of 2 mm.
