Advanced Polymer Coatings - High Performance Cargo Tank Coating

Advanced Polymer Coatings (APC) is a manufacturer of a wide range of Siloxirane® lining and coating systems, designed for demanding requirements for corrosion, high temperature and abrasion resistance. APC's MarineLine 784 product is a high performance coating for the marine transport industry.

MarineLine Coatings and Linings have been proven worldwide under arduous conditions. From resisting the most aggressive cargoes to handling hot cargoes in the sub-freezing Arctic, MarineLine has a history of success. Sailing into its tenth year of continuous successful service, MarineLine coated ships have withstood the tremendous stresses and extremes of changing chemical cargoes on almost a weekly basis.

MARINELINE 784 - HIGH CHEMICAL RESISTANCE

MarineLine provides more chemical resistance than other coatings, including Phenolic Epoxies, zinc and stainless steel. It is resistant to all 131 of the most frequently carried cargoes, whilst stainless steel is resistant to 97, Phenol Epoxy is resistant to 35 and Zinc Silicate is resistant to 22.

Furthermore, MarineLine is resistant to all IMO cargoes including the following: Methanol; EDC; Acrylonitrile; fatty acids; super Phospohoric; caustics; MTBE; MEA; Methylene Chloride and Sodium Hydroxide.

MarineLine provides superior resistance to the following: acids, alkalies and solvents; thermal shock (-40°C to +200°C); flex stressing; wear and abrasion; product absorbtion; impact and undercreep corrosion.

BENEFITS OF MARINELINE COATINGS AND LININGS

• Superior bond strength and adhesion
• Maximum cargo flexibility and product cycling
• Repairable
• Can be applied to pitted corroded steel
• Can carry food grade cargoes
• Maintains product purity
• Virtually non-absorbant

PROBLEMS WITH PHENOLIC EPOXY MARINE COATING

Compared to APC's MarineLine product, Epoxy coatings present several deficiencies. they absorb cargoes to high levels (depending on cargo), and have a relatively slow cargo absorbtion rate. Epoxy coatings release absorbed cargo very slowly. Furthermore, small traces may be retained by the Epoxy coating, contaminating the next cargo.

PROBLEMS WITH ZINC SILICATE COATING FOR CARGO TANKS

A Zinc silicate coating absorbs cargo quickly. It retains oil-like cargoes, endangering a subsequent cargo contamination. Zinc silicate coatings limit back hauling capability, and are not resistant to acids, caustics, acid-containing oils or urea.

PROBLEMS WITH STAINLESS STEEL COATINGS FOR MARINE TRANSPORT

Stainless Steel is four to five times more expensive than MarineLine coatings, and does not resist chloride-containing cargoes. Furthermore, stainless steel is attacked by salt water, has high maintenance costs and is more difficult to clean than MarineLine coatings.

MARINELINE COATING - DECREASED DOWNTIME

MarineLine's virtual non-absorbency (absorption only takes place after 45 days immersion) results in decreased downtime with faster tank cleaning. The MarineLine coating provides a faster drying time, and does not normally require the use of any cleaning chemicals. With less slops, it also ensures less environmental problems.

MARINELINE - SMOOTH CARGO AND TANKER COATING

MarineLine is 2½ times smoother than Phenolic Epoxy, five times smoother and 50 times less slippery than stainless steel:

• MarineLine - Surface roughness = 0.7Ra - 09.Ra; slipperiness = 34.0dynes/cm
• Phenolic Epoxy - Surface roughness = 1.8Ra - 2.1Ra; slipperiness = 80.0dynes/cm
• Stainless steel - Surface roughness = 3.2Ra-4.5Ra; slipperiness = 1800.0dynes/cm

MarineLine offers:

• Easy, safer and faster cleaning and drying
• No contamination from cargo to cargo
