Safely seals

Leak-free alternatives to pre-cut paper or cork gaskets, these new silicones are chemically neutral and odour-free. Their formulation requires no hazard labelling and Henkel says that this has been achieved without any compromise on performance.

The range comprises three products that meet the needs of most under-bonnet sealing tasks as well as a wide range of industrial applications. All are supplied in a  pressurised can with integrated nozzle for easy application.

Loctite SI 5980 Quick Gasket is a premium, high performance black silicone suitable for flanges that are in permanent contact with oil.

Characterised by its long term resistance to water and glycol the new Loctite SI 5660 is a grey silicone. Typical applications are sealing thermostats and water pumps.

The copper coloured Loctite SI 5990 is defined by its excellent temperature resistance – up to 350°C for temporary exposure. It is suitable for flanges in turbo charger housings, exhaust systems and for applications where resistance to water, glycol and oil is required.  

In common with all Loctite silicones, these new additions are said to provide outstanding long term durability.  They do not cause component corrosion, are extremely flexible and highly resistant to external stresses.  In addition to the 200ml self-dispensing can, these Health and Safety silicones can be supplied as a 40ml blister card, 100ml tube and 300ml cartridge.
