Glue for Plexiglas
To attach the canopy:
glue Teroson Macroplast UK 8303B60
hardener Teroson Macroplast UK5400
mixing ratio: 6 : 1 by mass
thickened with Aerosil.
To repair cracks in the canopy:
Röhm Acrifix 192 which hardens by exposure to light.
Filler
For gluing, the resin-hardener mix should be thickened with chopped cotton
fibres FL l f. (add enough so that the resin no longer flows). The surfaces to be
glued should be wetted with non-thickened resin + hardener before.
To glue foam pieces into place when repairing sandwich sections and to fill in
irregularities and gaps etc. around the repair, Microballoon BJO - 0930 can be
used mixed with the resin + hardener. Application and mixing is the same as for
the cotton flocks.
