- Storage and Transport
The product should remain stored in properly closed original containers, dry and cool (15- 25 °C). Do not transport at temperatures below +5 °C. For best-before date, please see container label. After the elapse of the best-before date, it is essential that you again verify that the product is fit for your intended application.
- General Bonding Requirements
The properties (e.g. Surface tension, plasticiser content...) and the conditioning of the substrates, as well as the processing conditions (e.G. Ambient temperature, humidity...) will influence the processes of joining and bonding. Customer tests under consideration of everyday production conditions are therefore absolutely necessary to define stable process parameters and to ensure that the product is fit for purpose. For best bonding results, the materials to be bonded should be free of dust, oil, and grease, and be dry. Ideally, the minimum temperature should be at 18 °c. Avoid draft.
