#187401 - Epoxy resins
Responding to: Oliver Sedlacek's previous message

Ap,
Epoxy resins typically have a maximum service temperature of around 130C, so many go soft or oxidise if heated to 150C. They are however much stronger, with a tensile strength of up to 80 MPa. Some like ResinTek E130-HT are also rated to 180C. In my experience, a big problem is that they are so strong that they can rip small components off their solder pads during the curing process as the epoxy moves.

Polyurethane compounds are the easiest to use, so I would suggest something like ResinTek U900 to start with as it wont damage delicate components.



Hello Oliver, But Epoxy resins are very prone to dissolving....
