Dow Corning 3145 Silicone Adhesive
It's not just the big components that can cause big problems. Smaller housings can cause trouble too, if they have cracks. Dow Corning RTV 3145 silicone adhesive sealant can take care of small openings and cracks in metal casings. This company that brought the world glass ovenware (Corning) knows a thing or two about making an adhesive that can stand up to moisture and extreme heat while staying strong.
