Fix built-in Electrolux oven door?

I have an Electrolux built in oven installed about 12 years ago. The outer oven door has come loose. The door is fixed at the bottom corners by two small plates - each with two small "pegs" which locate into two holes on the bottom corners of the door frame. The two small plates have become partially loose from the door frame. They have been originally fixed by some sort of "Dow Corning" mastic which I assume is high level heat resistant.
To repair I propose removing the small plates - cleaning off the old adhesive and re-sticking the plates back onto the door and refixing the door back onto the frame. Can you identify / sell the adhesive / mastic which I should use ?
