Hylomar Universal Blue

HYLOMAR UNIVERSAL BLUE
Non-setting gasket compound
Description
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.

Instructions for use
Hylomar Universal Blue should be applied to clean dry surfaces. Apply a thin film or bead to one or
both surfaces. Once applied, sufficient time should be allowed for the solvent to evaporate. Unlimited
assembly time allows precise alignment of joints to be made. Due to the nature of the compound,
fasteners may be required to be re-tightened to the correct torque.
Hylomar Universal Blue can be removed from dismantling components by rubbing with a cloth soaked
with Acetone. No scraping is necessary.
Information given in this publication is based upon technical data gained in our own and other Laboratories and is believed to be true. However the material is used in
conditions beyond our control thus we can assume no liability for results obtained or damages incurred through the application of the data present herein.

Typical 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.
Handling and Safety Properties
The compound is non-flammable
Product contains Dichloromethane
Labelling = Harmful. Carc cat 3. Phrases R40, S2, S23, S24/25 & S36/37.
Observe normal standards of industrial hygiene for handling chemicals. Avoid contact with skin &
eyes. Avoid breathing vapours.
Storage Precautions
Store in a cool, dry place between 5°- 25°C with adequate ventilation.
In climates where temperatures are likely to exceed 25oC we strongly recommend that the
customer buy cartridges rather than tubes.
Other Information
The shelf life is 2 years when stored in the original unopened containers as detailed above, for all
tubes, cartridges, and lever lid tins.
Packaging
Hylomar Universal Blue is available in 40 g tubes, 100 g tubes, 350 g cartridges, and 1 litre tins.
N.B. After filling, subsequent handling of the tube causes minor indentations. This may cause the
contents to be under a slight pressure. Care should be exercised when initially opening the tube as
a small amount of product may spurt out.
