The right glue for the right parts
Silicon as a glue
We use silicon to glue the back and front of the box. It acts as a glue - and also as seal. super glue, as we use it for the holders on the side of the box, doesnt work as a seal.
In this test we checked, if silicon has also sufficient adhearence properties.
Test parts can be found in this repository:
The adhesive surface is 4 cm2 each.
the force needed to separate the parts was:
13kg for the "double" parts (4 pieces glued together)
6kg for the "single" parts
The silicon did not bond with the ASA:
Similar results for Sika295 and Dosil732 - none bound really good with the ASA. Force needed part is similar - or worse - to the standard silicon used.
Also lightly sanding the surface of the ASA does not improve the bonding of the silicon.
