Protection

Offering Exceptional Performance

Polyurethane is a versatile synthetic material used across a wide range of industrial applications due to its outstanding durability, flexibility and resistance properties. Depending on the formulation, polyurethane can be engineered for use in protective coatings, paints, sealants, adhesives, foams and high-performance finishes.


Providing Polyurethane coating solutions for clients throughout the Northern Territory, helping protect valuable assets from wear, corrosion, chemicals, moisture and harsh environmental conditions.


One of the key advantages of polyurethane is its ability to be customised to suit specific applications. It can be formulated as a flexible coating for applications requiring movement and resilience or as a tough, hard-wearing finish designed to withstand heavy use and demanding conditions. Despite being applied in thin layers, polyurethane coatings provide excellent strength, durability and long-term protection.


Our experienced team can help determine the most suitable polyurethane coating system for your project, ensuring the right balance of performance, protection and finish.

  • What is abrasive blasting used for?

    Abrasive blasting is used to remove rust, corrosion, paint, scale and surface contaminants from materials such as steel, metal and other industrial substrates. It is commonly performed as a surface preparation method before applying industrial coatings, protective finishes or corrosion prevention systems.


    In heavy industry, abrasive blasting is especially important because it creates a clean, textured surface that coatings can properly bond to. Without proper preparation, coatings may peel, blister or fail prematurely, which can lead to costly repairs and downtime. Abrasive blasting is also used for restoration work, removing old coatings from machinery, vehicles and structural steel, and preparing surfaces for inspection, repairs or re-coating.


    Depending on the abrasive media used, blasting can be tailored for everything from aggressive rust removal to more controlled surface cleaning.

  • What’s the difference between sandblasting and abrasive blasting?

    Sandblasting is a type of abrasive blasting, but the term abrasive blasting is broader and more accurate today. Traditionally, sandblasting referred to blasting using sand as the abrasive material. However, due to health and safety concerns associated with silica dust, sand is less commonly used in modern industrial environments.


    Abrasive blasting can involve many different media such as crushed glass, steel grit, garnet and other engineered abrasives. Each abrasive has different cutting strength, surface profile results and suitability depending on the job.


    In industrial settings, abrasive blasting is typically preferred because it allows better control over the finish and is more compatible with modern corrosion prevention systems. The choice of abrasive material can also affect how well protective coatings adhere and how long they last.

  • How does abrasive blasting help with corrosion prevention?

    Abrasive blasting plays a major role in corrosion prevention because it removes the surface rust and corrosion that can weaken metal over time. More importantly, it prepares the surface for protective coatings by creating a clean profile, which helps primers and topcoats bond properly.


    When corrosion is left untreated, it can spread beneath coatings, causing them to lift or break down. Abrasive blasting removes those compromised layers and exposes a stable surface, giving protective coatings the best possible foundation.


    In industries such as oil, gas, marine and mining, this process is often the first step in long-term asset protection. A properly blasted and coated surface can withstand harsh weather, salt exposure, chemical contact and heavy wear far better than an untreated surface.

Frequently Asked Questions

  • What is polyurethane coating used for?

    Polyurethane coating is commonly used to protect surfaces from wear, corrosion, moisture and chemical exposure. It is widely applied across industrial, commercial and residential environments, but it is especially popular in heavy industry because of its durability and flexibility.


    Polyurethane coatings are often used on steel structures, industrial equipment, machinery parts and marine assets because they create a strong barrier between the surface and harsh external conditions. They can also be used as varnishes, paints, sealants, adhesives and foams depending on the product formulation. In many cases, polyurethane is applied as a topcoat to provide extra protection over primers and undercoats.


    One of the biggest reasons polyurethane is so widely used is that it can handle movement and vibration better than some other coating types. This flexibility helps reduce cracking or peeling over time, particularly in environments where equipment expands, contracts or experiences heavy use.

  • Is polyurethane good for corrosion protection?

    Yes, polyurethane is widely considered an effective coating for corrosion protection when it is applied correctly and used in the right environment. Polyurethane coatings create a protective barrier that helps prevent moisture, salt spray and contaminants from reaching the underlying surface, which is a major factor in corrosion development.


    In industrial settings, polyurethane is often used as part of a protective coating system rather than as a standalone solution. For example, it may be applied over a primer that provides strong adhesion and anti-corrosion properties, with polyurethane acting as the durable top layer that resists UV exposure, abrasion and chemical splashes.


    Polyurethane is particularly useful in coastal or marine environments where salt air accelerates corrosion. It is also commonly used in mining and oil and gas industries where surfaces are exposed to harsh conditions, heavy wear and chemical contact. The key to effective corrosion protection is ensuring the correct surface preparation and selecting a polyurethane product suited to the environment.

  • How long does polyurethane coating last?

    The lifespan of a polyurethane coating depends on several factors, including the product type, the surface it is applied to, the level of exposure to weather or chemicals and how well the surface was prepared before application. In many industrial environments, polyurethane coatings can last for years when applied as part of a properly designed coating system.


    In high-wear environments, such as areas exposed to constant abrasion, impact or heavy machinery traffic, polyurethane coatings may wear faster and require more frequent maintenance. In less abrasive environments, polyurethane coatings can maintain strong performance for extended periods, especially if they are protected from constant chemical exposure or extreme temperature cycling.


    Other factors that impact longevity include thickness of application, curing time and ongoing maintenance. Regular inspections and touch-ups can significantly extend the life of polyurethane coatings, helping prevent small surface failures from developing into larger corrosion issues.
