Jotacote F60 6A + Jotacote Universal N10
Jotacote F60 6A + Jotacote Universal N10 by Jotun AS. DNV TA certificate TAK00001YM.
Inspector Detail
▸
Common issues
- Poor surface preparation before application leading to early adhesion loss or blistering
- Coating breakdown or rust bleed at edges, welds and high-wear areas ahead of the rest of the system
- Application outside the specified temperature/humidity window causing slow cure or poor film formation
- Overcoating outside the maker's recoat window causing intercoat adhesion loss
- Mechanical damage from chain, gear or foot traffic contact breaking through to bare metal locally
Inspection checklist
- Visual check for blistering, cracking, chalking or rust bleed
- Dry film thickness spot checks against the specified nominal DFT
- Adhesion cross-cut check at any suspect or repaired area
- Check coating continuity/coverage at edges, welds and corners, typically the thinnest points
- Confirm any repairs were made within the product's recoat window, or that the surface was mechanically prepared if it wasn't
- Review application records (batch numbers, ambient conditions at application) if a defect is being investigated
Service intervals
| Visual condition survey | typically annual, aligned with routine class/owner inspections |
| Spot touch-up of local damage | as needed when damage is found, not on a fixed interval |
| Full system renewal | condition-based, commonly on the order of several years depending on exposure and mechanical wear - confirm against the specific product data sheet rather than a generic figure |
| DFT verification after any repair | at the time of repair, before returning the area to service |
Typical wear limits
| Dry film thickness | commonly checked against a tolerance band around the specified nominal DFT - confirm the actual tolerance against this product's own data sheet, not a generic figure |
| Recoat window | coatings applied outside the maker's stated recoat window commonly need mechanical roughening before overcoating - confirm the actual window in the product data sheet, since it varies by product and temperature |
| Remaining film condition | any breakthrough to bare metal or primer showing through the topcoat is treated as a limit reached locally, regardless of overall coating age |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Critical spares
- Same product line and batch/colour-matched paint for touch-up repairs
- Correct primer for the system - do not substitute without checking compatibility
- Thinner/reducer specified for this product, not a generic substitute
- Surface preparation materials matching the specified standard (e.g. correct abrasive grade)
- Application/PPE consumables appropriate to the product's safety data sheet
Safety
- Solvent-borne coatings are flammable during application and cure - no ignition sources, adequate ventilation required
- Isocyanate or epoxy hardener components can cause respiratory or skin sensitisation - use the respiratory protection and PPE specified on the product's safety data sheet
- Confined space precautions apply if application is inside an enclosed compartment or tank
Class survey
This entry could not verify manufacturer-specific technical data beyond the DNV Type Approval reference (certificate TAK00001YM) supplied with the record - confirm the actual product data sheet, recommended DFT and recoat intervals directly with Jotun before specifying or ordering. Class surveys of coating condition typically use a simple condition rating (good/fair/poor) rather than numeric wear limits.
