Hylomar Limited manufactures a wide range of high performance sealants and adhesives used by some of the leading OEM’s in the world of automotive, aerospace, white goods, power generation/distribution, electronics/photonics and general engineering.
The original product was developed in conjunction with Rolls-Royce and was used for sealing aircraft engines. Hylomar continues to manufacture Rolls-Royce approved products for sealing aeronautical turbines, Engine, compressor, electric motor, heavy industrial equipment, gearbox, defence industry component, turbine, automotive and many other original equipment manufacturers choose Hylomar non-setting compounds for their sealing and bonding applications.
Hylomar® is a polyester-urethane based sealant that transforms from a gel-like material into a re-sealable, non-setting, non-hardening putty within minutes of application. Because it is non-setting, Hylomar® sealant offers unlimited assembly time and is resistant to vibration and thermal expansion.
Hylomar® is the leading brand of non-hardening sealants for a wide variety of high temperature and oil resistant gasketing applications.
HYLOMAR is adopted world-wide in sealing petrol and diesel engines and automotive transmissions. Typical applications:Water and oil pumps, instrument inspection covers, cylinder heads and cast oil pans. Coating pre-formed gaskets,weatherproofing motors and outdoor high voltage circuit breakers. Inlet manifolds, timing case covers, oil pump joints, gearbox and transmission components. Thread sealing, gas turbines,water-cooled generators, turbo vacuum systems and any machined flange.
Hylomar is non-setting and nonhardening, even at high temperatures, and can be used to seal machined joint faces and threaded parts. Highly engineered non-setting and non-hardening
sealant compound specifically developed for use in the aerospace industry. Defence specification DTD 900/4586. HYLOMAR Aerograde carries Rolls Royce approvals MSRR9055 and OMAT numbers 4/46 (light) and 4/47 (medium). Hylomar products are resistant to a wide range of fluids including most industrial fuels, oils, 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) as well as some fluorocarbon refrigerants.
