FAIRING COMPOUND 202 CONVERTER

What is ALEXSEAL Fairing Compound 202 Converter and why choose it?

ALEXSEAL Fairing Compound 202 Converter (C2075) is the polyamine-based hardener component of the ALEXSEAL Fairing Compound 202 epoxy fairing system. Designed for professional, industrial serial painting, it reacts with the 202 bases to create a solvent-free, lightweight epoxy filler that cures without shrinking. When correctly mixed and applied, it delivers excellent anti-sagging performance, sandability and a stable surface for overcoating with other ALEXSEAL Yacht Coating products on yachts and other marine structures.

Main features

• Dedicated converter for Fairing Compound 202: Formulated to react with ALEXSEAL Fairing Compound 202 Standard Base (P2094) and Thick Base (P2083).
• Polyamine / amino-adduct hardener: Chemical nature specifically tuned for epoxy fairing applications.
• Solvent-free fairing system: The catalyzed system has 100% volume solids without reduction, helping to build thickness efficiently.
• Excellent application properties: Supports easy mixing, application with trowel or spatula and anti-sagging behavior of the 202 filler.
• High-build fairing capability: Suitable for build-up in multiple thin layers up to typical practical thicknesses of 6–10 mm when combined with the base.
• Fast or standard curing options: C2075 is the standard converter; the system can also use Fast or LV converters (C2017, C2028) where specified.
• Low VOC content: VOC content of the converter is 0.01 % (0.07 g/l) according to Directive 2010/75/EU.
• Professional-grade safety and handling information: Classified as corrosive and harmful; shipped and labeled under UN 3259, ensuring clear transport and handling guidance.

Applications and use cases

Typical applications

• Marine fairing on yachts: Filling and fairing of hulls and superstructures that require a smooth, stable surface for high-level yacht coatings.
• Above and below the waterline: When used within the complete ALEXSEAL Fairing Compound 202 system, the fairing material can be applied on suitably prepared substrates both above and below the waterline. Below the waterline it must be sealed with ALEXSEAL Finish Primer 442.
• Industrial serial painting: Designed for professional environments where consistent, repeatable fairing performance is required.

Suitable substrates within the system

• Metal substrates: After proper surface preparation and priming with ALEXSEAL Protective Primer 161. The fairing compound with converter may be applied directly to Primer 161 without sanding for up to 6 months after application.
• GRP substrates: Over correctly prepared surfaces primed with ALEXSEAL Super Build 302, High Build Primer 357, Finish Primer 442 or Protective Primer 161. All primers except 161 must be sanded with P60–P80 after overnight dry before applying the fairing compound.

Application guidelines (system)

• Application tools: Trowels, spatulas and straight-edge materials.
• Mixing control: Base and converter components are different colors to visually confirm complete mixing; the mixed filler should be homogeneous in color.
• Mixing method: Mix mechanically with slow-turning dough mixers or manually. Do not use drill mixers. Avoid entraining air.
• Application technique: Apply in thin layers and build up to the desired thickness, pulling out with a straight edge to minimize air pockets.
• Equipment cleaning: Use R4042 ALEXSEAL Epoxy Primer Reducer.
• Sanding: Block sand with P36–P120 grit. Finishing with P80 or finer helps prevent sand scratch print-through in the final coating system.
• Recoating with 202 over itself: Follow minimum dry-to-sand times; scratch sand with P36–P60 to ensure intercoat adhesion.
• Overcoating with other ALEXSEAL products: Products including 302, 303, 328, 357 and 442 may be applied after minimum time and block sanding with P36–P120.

FAQ – ALEXSEAL Fairing Compound 202 Converter

1. What is the role of the 202 Converter in the fairing system?

   The converter is the curing component for ALEXSEAL Fairing Compound 202. When mixed 1:1 with the base, it initiates the epoxy reaction, allowing the filler to cure, develop strength, anti-sag properties and a stable, sandable surface.

2. Can I thin or reduce ALEXSEAL C2075 Converter?

   No. ALEXSEAL Fairing Compound 202 must not be reduced. Do not add thinners to the base or converter when preparing the mix.

3. How long can I work with the mixed fairing compound?

   With C2075 or C2028 at 20 °C, pot life is approximately 50 minutes. At 15 °C it is about 1 hour and at 30 °C about 30 minutes. Always prepare only the amount that can be applied within the pot life.

4. When can I sand the fairing after mixing with C2075?

   At 20 °C, the system is typically dry to sand after about 24 hours when using C2075 or C2028. Lower temperatures require longer drying times; higher temperatures shorten them.

5. Is the converter suitable for use below the waterline?

   Yes, within the complete ALEXSEAL Fairing Compound 202 system on appropriately prepared substrates. Below the waterline, the cured fairing must be sealed with ALEXSEAL Finish Primer 442 before further coating.

6. Which tools should I use to apply the fairing compound mixed with 202 Converter?

   Apply with trowels, spatulas or straight-edge tools. Avoid using drill mixers for blending and avoid creating air pockets during application.

7. What are the storage conditions for the converter?

   Store in tightly closed original containers, upright, in a cool, dry, well-ventilated place away from heat, direct sunlight, oxidizing agents and strongly acidic or alkaline materials. Recommended storage temperature is 5–35 °C.

8. Is ALEXSEAL C2075 hazardous?

   Yes. It is classified as harmful if swallowed, causes severe skin burns and serious eye damage, may cause an allergic skin reaction, may cause damage to organs through prolonged or repeated exposure, and is very toxic to aquatic life with long lasting effects. Appropriate personal protective equipment and handling precautions are mandatory.

9. Can the converter be used on its own without the base?

   No. It is a hardener component and must only be used mixed with the specified ALEXSEAL Fairing Compound 202 bases in the recommended ratios.

10. How should leftover material and packaging be disposed of?

    Dispose of product and uncleaned packaging in accordance with local regulations. Contaminated packaging should be emptied as far as possible and cleaned before potential reuse or disposal.
