LOCTITE® SI 5990
Known as LOCTITE 5990
Features and Benefits
A 1-part, copper-colored, thixotropic, non-corrosive gasketing compound for applications involving large gaps.
LOCTITE® SI 5690 is a non-corrosive, oil-resistant, moisture-curing gasketing sealant, ideal for copper and applications involving large gaps. It can also be used for electrical insulating applications and is compatible with various surfaces, including metals and plastics. LOCTITE SI 5690 cures when exposed to moisture in the air to form a rigid rubber gasket. Its thixotropic nature makes it easy to apply and reduces sealant migration after application. LOCTITE® SI 5690 is label-free and offers excellent adhesive strength, even at temperatures up to 350°C (662°F).
