DESCRIPTION
Barrier
Pro 521 Coating is a single component,
latex polymer compound which forms a permanently flexible, elastic,
waterproof membrane. Barrier Pro Coating is resistant to hydrochloric
and sulphuric acid solutions exceeding 30 percent. The product is
highly resistant to water and salt penetration and the effects of most
chemicals. Barrier Pro Coating contains no volatile organic compounds
and is flame retardant. Barrier Pro Coating contains a built in biocide
and will not support mould growth.
Barrier
Pro Coating is ideally suited as a protective coating for
industrial applications where moist acidic or alkaline atmospheres
exist. Applied as directed, Barrier Pro Coating will protect steel
structural members and decking for up to 12 years without the need for
recoating.
Typical
applications would be steel mill clean lines, electroplating
shops, pulp and paper mills and mine installations.
APPLICATION
Barrier
Pro can be applied to steel surfaces showing surface rust, provided
that the steel is first cleaned using high pressure water blasting
combined with 5% bicarbonate of soda to adjust surface pH.
One coat of
our Neverox
Anti-Rust Emulsion is then applied.
After 24 hours, the surface
is then sprayed with one coat of Barrier Pro 920 Series Coating @ 80
sq. ft. per gallon using a high
pressure airless system. Allow 1 to 2 hours and apply a second coat at
the same rate. Airless spray settings: compressed air supply pressure
of 800 psi., compression
ratio of 28:1, tip size of .025” and a fan width of 8”. Typical airless
spray systems that work well with this product are: Graco Bulldog,
Graco GMAX II, Titan Speeflow 7900.
Because
there are no VOC’s and the coatings are non-flammable, they can
be used safely in enclosed areas without concerns about toxicity, fire
or explosion.
PRECAUTIONS
Although
Barrier Pro 521 Series Coating is unaffected by freezing when cured,
the
product must be protected from freezing prior to use as it is
perishable in the liquid state. Do not apply the product if freezing
conditions are imminent before the final cure period of the membrane.
Rubber or
nitrile gloves as well as protective clothing, splash goggles
and vapour respirator should be worn during application. 920 Series
Coating is extremely difficult to remove from skin or clothing once it
has cured. The product can be washed away with plain water prior to
curing. Equipment must be cleaned with fresh water immediately after
application.
