If the epoxy has filler or glass beads, will that interfere with the strength of the bond – and create the need for a thicker bond line?
If an epoxy has a filler or glass beads, the manufacturer has included the filler for a reason. The filler is part of the material’s properties – a component of the whole mixture – that contributes to achieving the adhesion and performance listed on the datasheet. Theoretically, there could be reduced strength if the dimension of the filler approaches the thickness of the bond line. Most fillers are much smaller than 1 mil (25 microns) and should be no cause for concern. However, you should always test the bond lines as described above to have confidence the adhered joint achieves the strength and stability needed for the application.
