What it is and why choose it
INTERCURE 3420HG PART A INDIVISIBLE KIT is the Part A base of Intercure 3240HG, a two-component, high-solids, low-VOC, fast-drying polyaspartic high-gloss primer/finish coating. Designed to be mixed with its dedicated curing agent (Part B), it delivers the anti-corrosive performance typically associated with epoxy coatings combined with the high UV durability and gloss of premium topcoats.
Applied as a single-coat, direct-to-metal system at ambient temperatures, it supports rapid handling and high production throughput without the need for force drying or baking ovens. This makes it particularly suited to OEM environments seeking to reduce application time, energy consumption and labor costs while maintaining high aesthetic and protective performance.
Main features
- Two-component polyaspartic system: Part A base formulated to be mixed with the corresponding Part B curing agent.
- High-gloss finish: Delivers >85 gloss units at 60° (when correctly applied as Intercure 3240HG system).
- High solids, low VOC: Approximately 84% ± 2% volume solids with typical VOC of 152 g/kg (EU Solvent Emissions Directive 2010/75/EU) for the mixed product.
- Fast drying at ambient temperature: Touch dry from 30 minutes at 25°C; hard dry from 2 hours at 25°C (mixed product, 50% RH).
- Single-coat direct-to-metal protection: Provides primer and finish performance in one coat over correctly prepared substrates.
- Energy-efficient curing: Rapid cure at 20–25°C helps avoid costly force drying and reduces energy consumption.
- Good adhesion: Performs effectively over correctly blast-cleaned steel profiles.
- Compatible with automated application: Suitable for manual (single-leg) and automatic (plural-leg) application systems.
- High productivity: Short handling times and high build in a single coat support high-throughput OEM lines.

Surface preparation and application
Surface preparation – steel substrates
- All surfaces must be clean, dry and free from contamination (oil, grease, dust, salts).
- Clean in accordance with ISO 8504:2000; oil and grease removal to SSPC-SP1.
- Abrasive blast clean steel to a minimum of Sa2½ (ISO 8501-1:2007) or SSPC-SP6.
- If oxidation occurs between blasting and application, re-blast to the specified visual standard.
- Recommended surface profile: 40–60 µm (1.6–2.4 mils).
- Lower profiles of 20–30 µm (0.8–1.2 mils) may be used to enhance overall aesthetics of the coating system.
Mixing and pot life (Part A + Part B)
- Material is supplied in two containers as a complete unit. Always mix a full unit in the supplied proportions.
- Agitate Base (Part A) thoroughly with a power agitator.
- Add the entire contents of Curing Agent (Part B) to Part A and mix thoroughly with a power agitator.
- Mix ratio (by volume): 2 parts Part A : 1 part Part B.
- Working pot life (mixed):
- 5°C (41°F): 2.5 hours
- 15°C (59°F): 2 hours
- 25°C (77°F): 75 minutes
- 40°C (104°F): 60 minutes
- At high relative humidity (>85%), pot life may be reduced; adding approximately 100 mL of GTA713 thinner per 20 L mixed unit can help maintain surface solvency in the can.
Application methods (mixed product)
- Plural component airless spray: Recommended. Tip size 0.33–0.48 mm (13–19 thou). Minimum total fluid pressure at tip 176 kg/cm² (2503 psi). Suitable proprietary equipment required.
- Single-leg airless spray: Recommended using suitable proprietary equipment (as above).
- Air-assisted airless spray: Suitable proprietary equipment; electrostatic application requires appropriate trials.
- Air spray (pressure pot): Recommended. Example set-up: DeVilbiss MBC or JGA gun with 704 or 765 air cap and E fluid tip.
- Conventional air spray: Recommended using suitable proprietary equipment.
- Brush: Suitable for small areas only; typically 80–100 µm (3.2–4.0 mils) DFT achievable.
- Roller: Suitable for small areas only; typically 80–100 µm (3.2–4.0 mils) DFT achievable.
- Thinner: International GTA713. Do not thin more than allowed by local environmental legislation. Do not use alternative thinners.

Application conditions and notes
- Relative humidity during application and cure should generally not exceed 85%; humidity above 50% may accelerate drying.
- Avoid application where condensation is likely; surface temperature must be at least 3°C (5°F) above dew point.
- Avoid dry film thickness above 200 µm (8 mils) to prevent excessive gloss build and potential defects.
- Level of sheen and surface finish depends on application method and DFT; avoid mixing application methods on the same job where possible.
- Ensure adequate ventilation, especially when applying in confined spaces.
- As with other fast-dry systems, control overspray to prevent contamination of previously coated workpieces.

FAQ
1. Is INTERCURE 3420HG PART A INDIVISIBLE KIT a complete coating?
No. It is the Part A base of a two-component system and must be mixed with the specified Part B curing agent at a 2:1 volume ratio to form the Intercure 3240HG coating.
2. Can it be applied directly to bare steel?
Yes, when mixed as Intercure 3240HG it is designed as a single-coat, direct-to-metal system on correctly prepared steel blasted to Sa2½ (ISO 8501-1:2007) or SSPC-SP6 with the recommended surface profile.
3. What application methods are recommended?
Plural-component airless and single-leg airless spray are recommended for high-production work. Air-assisted airless and air spray (pressure pot or conventional) are also suitable. Brush and roller are only recommended for small areas and touch-up.
4. How fast does the coating dry at 25°C?
At 25°C and 50% relative humidity, the mixed product is typically touch dry in about 30 minutes and hard dry in about 2 hours.
5. Is force drying or baking required?
No. The system is designed to cure rapidly at 20–25°C without high-temperature baking, helping to reduce energy consumption.
6. What is the recommended dry film thickness in one coat?
Typical application is 80–150 µm DFT in a single coat, with wet film thickness of approximately 95–179 µm.
7. Can I overcoat Intercure 3240HG with other products?
The product is designed as a single-coat system and no standard overcoating intervals with other topcoats are specified. Consultar ficha técnica del fabricante.
8. What is the VOC content of the mixed coating?
The typical VOC value of the mixed product is 152 g/kg in accordance with the EU Solvent Emissions Directive (2010/75/EU).

- Wear safety glasses with side shields or equivalent eye protection compliant with relevant standards when there is risk of splashes, mists or aerosols.
Hand protection
- Wear chemical-resistant, impervious gloves compliant with EN374 or equivalent.
- For frequent or prolonged contact, use gloves with protection class 6 (breakthrough time >480 min), recommended materials: Viton or nitrile, thickness ≥ 0.38 mm.
- For brief contact, use at least class 2 gloves (breakthrough time >30 min), recommended material: nitrile, thickness ≥ 0.12 mm.
- Replace gloves regularly and immediately if damaged or degraded.
Skin and body protection
- Wear appropriate protective clothing selected based on the task and risk assessment.
- Where ignition from static electricity is a risk, use antistatic protective garments, including overalls, boots and gloves conforming to EN 1149 or equivalent.
- Use suitable protective footwear and any additional skin protection as required, approved by a safety specialist.
Respiratory protection
- When ventilation is insufficient or risk assessment indicates, wear a respirator conforming to EN140 with A/P2 filter or better.
- Respirators must be used under a formal respiratory protection program ensuring correct selection, fit and training.
- During dry sanding, flame cutting or welding of the dry coating, wet methods are preferred. If exposure cannot be avoided by local exhaust, use suitable respiratory protection.
Hygiene and environmental measures
- Avoid breathing vapours, spray or mist; avoid skin and eye contact.
