What is SEAJET 039 PLATINUM PART A and why choose it?
SEAJET 039 PLATINUM PART A is the base component of Seajet 039 Platinum 2-Components, an advanced Self Polishing Copolymer (SPC) antifouling system. When mixed with its corresponding Component B, it delivers ultimate antifouling performance in the highest fouling areas and is ideal for blue water cruising yachts and other demanding marine applications. The system can be used on suitably primed GRP, wood and steel hulls and is not suitable for aluminium.

Drying and overcoating times (mixed product, 48 µm DFT)
- 5°C: Surface dry 3 h; hard dry 12 h; overcoating interval min. 12 h, max. none; dry to launch 24 h.
- 10°C: Surface dry 2 h; hard dry 8 h; overcoating interval min. 8 h, max. none; dry to launch 18 h.
- 20°C: Surface dry 1 h; hard dry 5 h; overcoating interval min. 5 h, max. none; dry to launch 12 h.

Drying times and overcoating intervals will increase with increasing film thickness. Before recoating, always ensure the existing film is fully dry.
Applications and use cases
Recommended uses
- Antifouling protection for sailing yachts and motorboats cruising in high fouling regions.
- Blue water cruisers requiring long-term, high performance fouling protection.
- Superyachts and performance vessels operating at varied speeds.
Suitable substrates and primers
- Existing antifouling (good condition): High pressure fresh-water wash (±200 bar), check SEAJET compatibility table. If compatible, apply directly.
- Existing antifouling (poor condition): Remove old antifouling. Wet sand or chemically strip only. Never burn off or dry sand.
- GRP / Steel (new application): Sand with P100 abrasive paper, remove dust and apply SEAJET 117 Multipurpose Epoxy Primer.
- Wood (new application): Sand with P100 abrasive paper, remove dust and apply SEAJET 015 Underwater Primer.
- Aluminium: Do not use Seajet 039 Platinum 2-Components on aluminium surfaces.
Coating system recommendations
- Preceding coats: SEAJET 015 Underwater Primer or SEAJET 117 Multipurpose Epoxy Primer (apply Seajet 039 within 48 hours when applied directly over Seajet 117).
- Number of coats: Apply two coats as standard, with an extra coat on leading edges, waterline, rudders and stern gear.
- Subsequent coats: --
Mixing and application notes for Part A
- Add Component B gradually to SEAJET 039 PLATINUM PART A while mechanically mixing.
- Do not add all of Component B at once; divide into 3–4 portions during mixing.
- Stir thoroughly before use to obtain a homogeneous mixture.
- Due to the chemical reaction, the product may thicken; as long as it is applied within the specified pot life there should be no problem.
- For airless spray application, use the product within 4 hours after mixing and use a prefilter.
- After immersion, the coating may exhibit a slight colour change. Colour differences between batches may occur; mix different batches together before use if necessary.
FAQ
