Transocean Optima 2.32 Antifouling Blue 4L | Marine Growth Protection

🔧 Product Description

Transocean Optima 232 AU Self-Eroding Antifouling - Blue 4L - Reference: TO 2.32AU Blue 4L

A professional blue cuprous-oxide antifouling for submerged vessel hulls. The Australian Optima 232 AU formulation is a tin-free, self-eroding coating that gradually renews its active surface in service, helping protect against marine fouling for extended periods when applied over a compatible anticorrosive and tie-coat system.

⚙️ Key Features

• Designed for protection periods up to approximately 18 months and occasionally up to 24 months, depending on service conditions
• Compatible with approved Transocean anticorrosive coating systems
• Complies with the IMO Antifouling System Convention and is registered for Australian use

🔄 Related & Comparable Products

• Comparable polishing/self-eroding antifouling categories include International Micron Extra 2 and Hempel Mille NCT
• Comparable coatings are not direct overcoat substitutes; confirm compatibility, primer system, active chemistry and local registration before changing products
• Other Transocean systems may be preferred for different vessel speeds, service intervals or fouling environments

🎨 Application & Suitability

• Suitable for appropriately prepared steel, fibreglass, timber and other approved hull substrates over the specified primer or tie coat
• Apply by airless spray, brush or roller in accordance with the current Transocean product data sheet
• Use additional coats or stripe coats around waterlines, leading edges, chines, rudders and high-wear areas where the coating specification requires them
• Practical coverage will be lower than theoretical coverage because of surface profile, roller or spray losses, overspray and hull geometry
• Select colour and total film build as part of the complete antifouling specification

⚠️ Application Notes & Safety

• Do not apply directly to bare aluminium or other reactive metal without a manufacturer-approved barrier system
• Confirm the existing antifouling and tie coat are compatible before overcoating
• The hull must be clean, dry, sound and free of salt, oil, slime, loose paint and contamination
• Use only the specified Transocean thinner or cleaner when required and avoid excessive thinning
• Observe current temperature, humidity, recoating and launching windows from the product data sheet
• Contains cuprous oxide and solvents; use approved respiratory, eye, skin and environmental controls
