H.B. Fuller 1956

3mm thickness in 24 hr; Full-cure is 7 Days at 25°C at 50% R.H. or 5 hours at 70°C.

• If storing below 25°C, bring material to room temperature 24 hours before using
• Prior to bonding, surfaces must be clean and free of any dust, oils, or other contaminants
• Using preheated substrates can reduce the time prior to handling
• Apply adhesive to one or both of the surfaces to be bonded. The surfaces can then be assembled and heat cured immediately.It is not recommended to use 1925 at temperatures below 5°C or higher than 35°C.
• 1925 is typically dispensed through a nozzle that has an opening with the desired dimensional extrusion size. This is done by cutting the opening on a cartridge of sausage pack tip or with custom metal designed nozzles for bulk dispensing. Once the packages are opened, it is recommended to use the shortest possible time to apply the materials.
• It is not recommended to reseal and use the material at a later date. After material is applied it can be smoothed with a spatula and soapy water. 1925 material surface can be painted after it is fully cured. It is highly recommended that a pre-test be done on a small sample area to confirm paint compatibility and adhesion.

For optimum shelf life, store below 5°C. Partially used containers should always be nitrogen purged to prevent moisture contamination, which could result in pressurized containers. Moisture contaminated material cannot be recovered.
