Sigma Coatings specialises in systems which offer the utmost protection in the most severe environments, than can adhere to the most difficult surfaces and that can be applied under imperfect working conditions.
POWER GENERATION AND DISTRIBUTION
Sigma Coatings was one of the first coating brands to develop products to meet the very specific needs of the power industry. We offer a full range of coating solutions, providing protection across all sectors within the Power generation and distribution such as nuclear, wind power and hydropower plants around the globe.
Our expertise has ensured a long and successful track record in power plants with solutions for corrosion protection, epoxy systems with good chemical resistance and specially developed coatings for handling extremely high temperatures as well as chemical and ash abrasion for the following areas:
Marine - Newbuilding, maintenance & Repair
Our Marine coatings brings unrivaled levels of experience and expertise in coatings technology to answer the ever-changing needs of major asset owners, ship builders and maintenance yards, consulting engineers and the construction industry.
Correct coating choice and application at the new-building stage is the easiest way of ensuring that the coatings applied will provide maximum corrosion protection, thus improving the vessel's efficiency and helping to reduce on-board maintenance costs.
The building of a new vessel involves a large investment for the owner and is a labour intensive process for the shipyard. Coatings form a relatively small part of the total vessel cost, yet they are a key factor in subsequent asset protection, safe operation and maximising revenues when the vessel is in service. Maintenance with coatings prevents the steel from returning to its original oxidised state during the course of the vessels life. It slows the rate of the decline in value and well-planned maintenance with specialty designed coatings can provide a substantial increase in service life. Therefore good coating maintenance practice is really asset protection.
Sigma Coatings Marine coatings offers a unique range for new-building and maintenance designed to cope with the most demanding service conditions whilst at the same time being designed to allow efficient application in shipyards. These coating systems provide both productivity benefits for the shipyard and superior performance for the owner.
Our marine coatings products are available worldwide, providing coatings for the protection of ocean going and coastal vessels.
The mining industry is a big volume sector for new projects and maintenance in South Africa. Sigma Coatings understands the needs and requirements in this industry. Our expertise is extensively used in the Gold, Coal, Diamond and Platinum sectors
Infrastructure is a diverse field covering a wide variety of structures many of which involve huge investment and which are exposed to corrosive environments.
Some examples are
Bridges have benefited from the increases in the durability of modern coating systems developed for markets such as marine and offshore. Both long term corrosion resistance and aesthetics have benefited, as has maintenance of less than perfectly prepared services Bridge coating systems generally have to be approved by bodies in the country where the bridge is located. Sigma Coatings has approvals and extensive experience.
Sigma Coatings Protective coatings has a range of products that are ideal for the protection of civil structures. Key aspects are long service periods between maintenance, abrasion resistance and colour and gloss retention. Nowadays the majority of structures are fabricated and easy in-shop application of all or part of the coating system is crucial. The SigmaFast range of products efficiently balances the needs of the contractor with those of the specifier and client - easy in-shop application, fast curing and good site performance and appearance.
Sigma Coatings has a unique range of products for the refurbishment of cladding.
The following products are suitable for use on civil structures and infrastructure:
Sigma AquaCover, SigmaCover, SigmaDur, SigmaFast, SigmaLine, Sigmarine, SigmaShield, Sigma Vikote, SigmaWeld, SigmaZinc
Whilst Sigma Coatings' protective coatings have applications across a wide range of industrial sectors, there are specific areas in which we offer outstanding levels of technological expertise, product superiority and dedicated technical field support. The markets we serve are diverse and Sigma Coatings are committed to work closely with Asset Owners, specifiers, engineers, project managers, contractors etc.
