Hylomar® Product Range

Hylomar® Universal Blue

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 kerosene fluids (Avtur & Avcat) and fluorocarbon refrigerants. Hylomar® Universal Blue can be used to seal joint faces or threaded parts.

Applications

Hylomar® Universal Blue enables the effective sealing of metal to metal and plastic to plastic components. Typical applications include water and oil pumps, instrument inspection covers, cylinder heads and sumps, and it can also be used for the coating for pre-formed gaskets, weather proofing, motors and outdoor high voltage circuit breakers. Inlet manifolds, timing case covers, oil pump joints, gear box and transmission components or thread sealing it has also been successfully been used in the assembly of gas turbines, water cool generators and turbo vacuum systems. There is no staining of copper and silver, etc., from traces of volatiles at elevated temperature, and is therefore suitable for joints, and threads in close proximity to switch mechanisms, etc.

LIGHT GRADE: Inlet manifolds, timing case covers, oil pump joints, gearbox and transmission components, thread sealing and any finely machined surface.

MEDIUM GRADE: Water and oil pumps, instrument inspection covers, cylinder heads, sumps and most machined surfaces.

HEAVY GRADE: Gas turbines, water cooled generators, turbo vacuum systems, gearboxes and most rough machined surfaces.
