Anti-Corrosion Solutions | Nippon Paint Professionals

Protect surfaces that are highly prone to corrosion, rust and the detrimental effects of the environment which lead to weaker structures, reduced value of goods and gain a high cost of fixing. Our anti-corrosion solutions encompass both conventional and heavy-duty type coatings — ideal for any metal surface such as structural steel works, storage tanks (for edible products, fuel, oil water etc.), pipes, piles, vessels and metal bridges.

A Globally Recognised Standard For Corrosion Protection

ISO 12944 has the best practices in protecting structural steel surfaces. It all starts by ‘Selecting the environment’ and ‘Selecting the lifespan’ to pick out your desired durability.

SAFEGUARD ANY SURFACE WITH ISO 12944

ATMOSPHERIC-CORROSIVITY CATEGORIES AND EXAMPLES OF TYPICAL ENVIRONMENTS

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 sulfur dioxide pollution; coastal areas with low salinity	Production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries, dairies
C4 High	Industrial areas and coastal areas with moderate salinity	Chemical plants, swimming pools, coastal ships and boatyards
C5 Very High	Industrial areas with high humidity and aggressive atmosphere and coastal areas with high salinity	Buildings or areas with almost permanentcondensation and with high pollution
Cx Extreme	Offshore areas with high salinity and industrial areas with extreme humidity and aggressive atmosphere and subtropical and tropical atmospheres	Industrial areas with extreme humidity and aggressive atmosphere

Note: Corrosivity categories can also be estimated by considering the combined effect of the following environment factors: yearly time of wetness, yearly mean concentration of sulfur dioxide and yearly mean deposition of chloride (see ISO 9223). The loss values used for the corrosivity categories are identical to those given in ISO 9223.

CATEGORIES FOR WATER AND SOIL

Category	ENVIRONMENT	EXAMPLES OF ENVIRONMENT AND STRUCTURES
IM1	Fresh water	River installations, hydro-electronic power plants
IM2	Sea or brackish water	Immersed structures 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

Durability	YEARS TO FIRST MAJOR MAINTENANCE
Low (L)	Up to 7 years
Medium (m)	7 to 15 years
High (H)	15 to 25 years
Very high (VH)	More than 25 years

Type Of Coatings

Conventional Protective Coatings

Nippon Paint’s conventional protective coatings are specially developed to protect surfaces under normal service conditions, an environment of light moisture condensation and presence of mild corrosive chemicals.

Heavy-Duty Type Coatings

Nippon Paint also has an extensive range of heavy-duty protective coatings that are designed to protect surfaces under severe service conditions, exposed to an environment of medium to high condensation and presence of corrosive chemicals.
