Use Instructions for Crystalbond™ 509*, 555, 555-HMP and 590
- Using a hot plate or oven, heat a ceramic or glass mounting block to
the flow temperature of the selected Crystalbond™ adhesive. Make
sure to work in a well-ventilated area, and do not overshoot the flow
temperature, otherwise, the adhesive will begin to decompose,
degrading its strength.
- Apply a uniform layer of adhesive to the heated mounting plate and
place the substrate over the adhesive. Using a weight, apply even
pressure to the substrate to remove air bubbles and to ensure that
the substrate is parallel to the plate. Apply a fillet of adhesive around
the perimeter of the substrate to increase the holding strength.
- Remove the mounting plate from the heat source and allow it to cool
slowly to room temperature until the adhesive is hardened. Cool for
20-30 minutes before processing.
- Dice or process the substrate as required, then remove the parts by
re-heating the mounting block to the flow temperature. Use a tool to
slide the substrate off the mounting plate.
- For detailed cleaning procedures for Crystalbond™ 509 and 590,
refer to the pages for Crystalbond™ 509-S and 590-S Strippers. For
Crystalbond™ 555 or 555-HMP, follow the Process Diagram for
cleaning, substituting water for the other strippers.
Crystalbond™ 509 can be applied as a thin, uniform film by dissolving
it into a sprayable liquid. This can be accomplished by crushing the
adhesive stick into a powder and mixing it into a solution of 80 parts
acetone to 20 parts 509 by weight. Spray the solution onto the parts and
allow the solvent to evaporate for a minimum of 5 minutes. Use a heat
gun for one minute at less than 250 °F to evaporate further, then press
the parts together and cool at room temperature for at least 30 minutes.
