Protective Coatings

Protective Coatings are essential to achieve the full service life of most assets.

Billions of dollars are spent every year repairing and replacing the effects of corrosion, chemical attack, wear and abrasion. A good protective coatings strategy can reduce that spend dramatically.

Assets – buildings, bridges, steel structures, concrete slabs, runways, roofs, walls, bunds – have to compromise between their internal and structural properties, and resistance to the outside world.

The surface of any asset is where it is first attacked by nature, humans, traffic, chemicals, pollution, temperature changes, radiation and more. As the outer surface is degraded, the asset becomes more vulnerable to failure or early retirement.

Australasian Specialty Coatings will provide the best barrier on that surface to protect the asset, extending the service life and protecting your investment.

The protective coatings we offer can be broken down into the following areas. If there’s something you need, Contact Us to discuss your options.

Corrosion Protection Coatings

Every year billions of dollars are spent replacing assets that have corroded beyond their design tolerance. Billions more are spent rehabilitating less-corroded assets.

Australasian Specialty Coatings has NACE qualified staff and estimators. We can offer corrosion prevention treatments for any surface worth protecting. As well as a wide range of coatings, we work with you to determine the right strategy.

Acid/Chemical Resistant Coatings

Many operations have areas where unusual or aggressive chemicals must be stored and handled. Oils, cleaning detergents, CIP chemicals, batteries and strong acids and alkalis used in production processes all attack and break down concrete and many corrode steel.

Australasian Specialty Coatings can select and install specialist or custom-formulated materials designed to resist chemical attack and contain dangerous chemicals.

We will consider every chemical agent to which a surface may be exposed and then assign the right materials for the task. Our customers regularly rely on our expertise to contain and isolate acids, alkalis, solvents, oils, greases, animal by-products, coolants, fuels, alcohols and other aggressive substances.

Australasian Specialty Coatings is experienced in applying Secondary Containment materials such as Novolac Epoxies, Polyaspartics, Polyurethanes and other coatings to protect bunds and chemical storage areas. See also our Protective Coatings page or Tank Linings and Immersibles.

Immersion Coatings and Tank Linings

Very special attention needs to be paid to coating and lining systems that spend their life immersed in liquids.

These coatings are usually very specific to the environment in which they are installed. They are chemically formulated to ensure that the substrate is completely isolated from the liquid being contained. Detailed preparation, installation and testing is required to complete a successful installation.

Australasian Specialty Coatings work with clients and suppliers to understand the nature of the surface to be coated, the chemistry of the environment and the best materials and methods for the task.

Our NACE Qualified staff are required by most coatings manufacturers for these projects. Independently audited Quality Assurance provides the confidence for critical installations.

Sacrificial Coatings

Most coatings are designed to protect a surface or asset from aggressive attack by abrasion, impact or corrosion.

A sacrificial coating may be chosen when it is impossible to repel the attack, or if a sacrificial coating is more affordable over the life of the asset. The coating is abraded and depleted over time and is designed to be regularly replaced or topped up.

Sacrificial coatings can be various levels of thickness and strength to achieve different results. Longevity can be tailored to the environment, budgets and maintenance schedule.

Common areas for sacrificial surfaces to be used are:

  • Areas of high friction and high shear – turning zones, loading ramps, tipping floors
  • Areas holding abrasive materials – raw materials holding yards, mining processes
  • Areas with aggressive chemicals – waste transfer stations, surge tanks
  • Impact areas and drop zones

A waste transfer station tipping floor, where tons of raw materials are tipped before being bulldozed to an adjacent compactor, is subject to the impact of the material as it is unloaded, the intense friction of the material and the steel bucket edge of the front end loader as the waste is moved across the surface, and the chemical attack of the liquids from the waste.

A well designed sacrificial layer can be worn away slowly, preserving the concrete slab beneath.

High Temperature Coatings

High-temperature coatings are designed to prevent the corrosion of metal surfaces which are exposed not only to high heat, but to high humidity, condensation, corrosive gases, and salt air environments.

These coatings must be designed specifically for each particular harsh, corrosive situation and must be able to cope with extreme conditions placed upon them. High temperature coatings need a track history to prove their capabilities as many coatings claim to offer longevity in such aggressive conditions but very few do.

Power, cement and chemical plants, refineries, offshore rigs and other marine environments all have different needs with specific solutions.

At Australasian Specialty Coatings we ensure the product installed fits the criteria and the life span of the project specified.

Surface Preparation

The key to ensuring longevity of any coating is in the surface preparation. Without the correct substrate profiling the project will be flawed from the outset.

Selection of the most appropriate method of preparation requires careful consideration of the specific requirements of both the surface and the coating. At Australasian Specialty Coatings our team of qualified staff ensures that the right type of preparation is carried out every time works are undertaken.

From abrasive blasting of steel in sensitive environments to the removal of contaminated concrete over large areas we have the staff and equipment to complete the job on time every time.
