Corrosion Control With Plurotech RustEx*Hypercote™
 
 

A New Improved High Performance Waterborne Coating.

RustEx*Hypercote™ is a waterborne, single pack, elastomeric chloropolymer coating containing a blend of unique, complex anticorrosive pigments. The coatings dries to form an extremely flexible and highly impermeable barrier. RustEx*Hypercote™exhibits excellent adhesion to a wide variety of substrates which combined with its excellent chemical resistance mean the coating can be used for the protection of storage tanks containing a wide variety of aggressive chemicals.

Suggested Uses:

Plurotech RustEx*Hypercote™ has been successfully used on automotive shells and chassis, potable water tanks, steel bridges, brine tanks, harbour installations, lamp posts, oil rigs, railings, sewage treatment works, storage tanks, structural girders and railway vehicles.

CONSIDER THE FOLLOWING BENEFITS:

It is 100% water based; non toxic (acid free); non solvent and environmental friendly. Extremely user friendly and needs no thinner or solvents. It can be applied direct on metal surfaces without primer. Non flammable and non-inflammable - classified as General Cargo.

Preparation

  • Rusted Steel RustEx*Hypercote™ is tolerant of lightly rusted surfaces, however for heavily rusted surfaces, it should be pre-treated with RustEx*Hypercote™ Rust Converter.
  • Cold Rolled Steel Abrade & degrease.
  • Hot Rolled Steel Blast clean to Sa 2.5.
  • Aluminium Degrease.
  • Galvanised Steel Degrease.
  • Fibreglass Degrease

Application

It is recommended to carry out an initial test at all times. This test should take place in the working conditions of application. The topcoat system should be also be tested for compatibility. Stir the product thoroughly before use. Apply a minimum of TWO coats by brush, spray or roller to achieve a wet film thickness of 115-170um per coat (50-75um DFT).

BRUSH: Apply product evenly by brush using multi-directional strokes to ensure adequate coverage of the substrate

ROLLER: Use a short nap roller and apply the coatings evenly; edges may need to be stripe coated by brush to ensure complete coverage.

SPRAY: The coating may be applied by air assisted or airless spray techniques, typical gun settings are as follows:

 

 Airless Spray

 Air Assisted (siphon or pressure fed)

 100-130kg/cm2 (1,400-1,800 psi)  3.5-4kg/cm2 (50-60psi)
 250-400um tip  250-400um tip
 40-60 degree fan  40-60 degree fan
 For siphon fed guns dilution with up to 30% water is required.
 

Atmospheric Conditions

External
An air temperature of 5-30 deg C (40-86 deg F) is preferred, avoid applying if relative humidity is greater than 80%. Avoid applying if there is a risk of rain or condensation during the drying period.

Internal
Ensure air movement is available to remove excess moisture during the drying process.

Cleaning

Immerse brushes, rollers or spray tips in clean water during work breaks to prevent paint drying. Use water to clean equipment before paint dries. To remove dried paint use lacquer thinner or aromatic solvent.
