Hylomar Universal Blue is one of the world's leading non-setting gasket and jointing compounds, widely used in the automotive, aerospace, defence and general engineering industries where a non-setting, flexible seal is required.
Hylomar Universal Blue is a polyester urethane based sealant that is non-setting and non-hardening even at high temperatures. The compound is resistant to a wide range of fluids including all industrial fuels, oils, water and brine, air, turbine and piston engine combustion products, water, water/glycol and methanol mixtures, petroleum and synthetic diester lubricating oils, gasoline and kerosine fluids (Avtur & Avcat) and fluorocarbon refrigerants. Hylomar Universal Blue can be used to seal joint faces or threaded parts.
