521 Acid Resistant Coating
WATERPROOF COATING RESISTS UP TO
HYDROCHLORIC & SULPHURIC ACID SOLUTIONS
FOR PROTECTING STRUCTURAL STEEL AND ROOF DECKING, IN PLATING
FACILITIES, ACID CLEAN LINES, STEEL MILLS, PAPER
MILLS, AND MINING INSTALLATIONS.
EXCELLENT ADHESION TO STEEL,
FOAM INSULATION, ALUMINUM AND CONCRETE
BY HIGH PRESSURE AIRLESS SPRAY
•WATER BASED - EASY CLEAN-UP
•NON TOXIC, NON-FLAMMABLE
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 up to 32 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.
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
applications would be steel mill clean lines, electroplating
shops, pulp and paper mills and mine installations.
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
Anti-Rust Emulsion is then applied.
After 24 hours, apply two coats Barrier Pro 521, using a high
pressure airless system. Aplly each coat at 80 sq ft/gal and allow 1 to
2 hours dry time between coats. Typical airless
spray systems that work well with this product are: Graco GH833,
Graco GMAX II 7900, or Titan Speeflow 7900. Airless spray settings are
as follows: compressed air supply pressure
of 800 psi., compression
ratio of 28:1, tip size of .025” and a fan width of 8”.
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. Respirators must be worn in confined spray areas to
prevent inhalation of adhesive vapors.
Barrier Pro 521 Series Coating is unaffected by freezing when cured,
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.
Barrier Pro 521 should not be used in applications where ambient
temperatures exceed 130ºF (54.4ºC)
nitrile gloves as well as protective clothing, splash goggles
and vapour respirator should be worn during application. Barrier Pro
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
