Loctite 5660/100ml – Flange Sealent
Loctite SI 5660 Silicone Sealant – excellent adhesive strength. Ideal for applications involving large gaps. Label-free. Excellent resistance against water/glycol.
Loctite SI 5660 is a moisture curing silicone. The thixotropic nature of Loctite SI 5660 reduces the migration of liquid product after application to the substrate. It has been designed specially for gasketing applications where good resistance against oils and coolants is required. Typical applications include transmissions and cast metal housings.
