Mention paint and the first thing that usually comes to mind is to give the space a new look. However, paint and coatings offer a myriad of functional solutions beyond just enhancing wall surface aesthetics.
As mentioned, besides providing a dash of colour, paint and coatings provide a layer of added protection to surfaces. Take for instance infrastructures such as bridges, train stations and airports. These projects have extremely high safety requirements and protocols – and are meant to last a lifetime. Being constantly subjected to demanding conditions and the harsh environment, it is only vital that they be protected to prevent any untoward incidents.
For instance, unprotected steel structures are exposed to the elements, which may lead to corrosion, and this will affect the structural integrity. Hence, it is important to apply tried and tested protective coatings for longevity and reduced maintenance costs, in addition to enhance the structure to prevent it from rust.
To assure peace of mind for its users, Nippon Paint Protective Coatings, the professionals preferred solutions, always adhere to stringent quality controls. They also comply with ISO 12944, an international standard on corrosion protection of steel structures by protective paint systems. Thus, you can enjoy quality in every drop to fulfil your project’s purpose.
Where to begin? First, when selecting the best coating system for your project, you must consider the environment and then the desired durability – as outlined in ISO 12944.
Befitting its status as “Asia’s No. 1 Total Coatings Expert”, Nippon Paint offers all-inclusive products catering to a wide array of solutions, from basement to roof and every layer in between, from architectural and industrial coatings to protective coatings and many more!
1. Determine the environment
| Corrosivity category | Exterior | Interior |
|---|---|---|
| C1 (very low | - | Heated buildings with clean atmospheres (e.g. offices, shops, schools, hotels) |
| C2 (low) | Atmospheres with low level of pollution: mostly rural areas | Unheated buildings where condensation can occur, e.g. depots, sports halls |
| C3 (medium) | Urban and industrial atmospheres, moderate sulphur dioxide pollution; coastal areas with low salinity | Production rooms with high humidity and some air pollution (eg. food processing plants, laundries, breweries, dairies) |
| C4 (high) | Industrial areas and coastal areas with moderate salinity | Chemical plant, swimming pools, coastal ship and boatyards |
| C5 (very high) | Industrial areas with high humidity and aggressive atmosphere and coastal areas with high salinity | Buildings or areas with almost permanent condensation and with high pollution |
| CX (extreme) | Offshore areas with high salinity, industrial areas with extreme humidity and aggressive atmosphere and subtropical and tropical atmospheres | Industrial areas with extreme humidity and aggressive atmosphere |
Corrosivity categories can also be estimated by considering the combined effect of the following environment factors: yearly time of wetness, yearly mean concentration of sulphur dioxide and yearly mean deposition of chloride. The loss values for the corrosivity categories are identical to the those given in ISO 9223.
| Category | Environment | Examples of environment and structures |
|---|---|---|
| IM1 | Fresh water | River installations, hydro-electronic power plants |
| IM2 | Sea or brackish water | Immersed structure without cathodic protection (e.g. harbour areas with structures like sluice gates, locks or jetties) |
| IM3 | Soil | Buried tanks, steel piles, steel pipes |
| IM4 | Sea or brackish water | Immersed structures with cathodic protection (e.g. offshore structures) |
Note: For corrosivity category IM1 and IM3, cathodic protection can be used with a paint system tested accordingly
2. Desired durability
| Durability | Years to first major maintenance |
|---|---|
| Low (L) | Up to seven years |
| Medium (M) | Seven to 15 years |
| High (H) | 15 to 25 years |
| Very high (VH) | More than 25 years |
Once you have determined the environment and desired durability, it is time to choose an ISO 12944-recommended coating system for your project. There is an extensive range of coating systems offered by Nippon Paint which are readily available in the market today.
The systems cater to both atmospheric and immersion corrosion condition and Nippon Paint Protective Coatings are specially formulated solutions that protect surfaces that are highly prone to corrosion, rust and the other detrimental effects from the environment.
These are ideal for any metal surfaces, for example structural steel works, storage tanks (even for edible products, fuel, oil, water and more), pipes, piles, vessels and metal bridges.
As a testament to its reliability, thousands of completed projects in Malaysia such as KVMRT Sungai Buloh Depot, Selangor; Saloma Bridge, Kuala Lumpur; Kimanis Power Plant, Sarawak; Kelloggs Factory, Negeri Sembilan; Kuala Lumpur Convention Centre and many more have employ Nippon’s coating solutions for their high durability, longevity and resistance to the elements – allowing them to stand the test of time.
