I'd like to "improve" MCH heater (50*50*1.5mm) for DIY reflower: add panasonic PGS on top side and aluminium foil on bottom side. That requires glue, operating at least on 300C, ideally up to 400C. Also, this glue should dry without air access and be easily available worldwide (ideally - at ebay/aliexpress).
Could you advice something suitable? Note, i know about RTV-1 silicones, those need air access to dry. The same with popular cements for car's smoke system. It would be nice to get something 2-components or temperature-activated, liquid enough for thin layer.
