Ship hardener WS206A

Overview
Slow hardener 206 is a low-viscosity epoxy curing agent formulated to extend working time and provide a longer cure when required. When combined with Epoxy Resin 105, the cured system yields a rigid, high-strength, moisture-resistant solid suitable for bonding and non-transparent coatings.

Key properties

• Low viscosity for improved wetting and easier application
• Extended working (pot) time and slower cure profile
• Cured system is rigid, high-strength and moisture resistant when mixed with Epoxy 105
• Not formulated for clear or transparent topcoats
• May emit a strong ammonia-like odor during cure

Working times & cure

• Pot life at 25°C: 20–30 minutes
• Cure to solid state at 21°C: 9–12 hours
• Full mechanical strength at 21°C: 5–7 days
• Minimum recommended working temperature: 16°C

Consumption

• 1 kg mixture on porous surface at 25°C: 6.5–7.5 m²
• 1 kg mixture on non-porous surface at 25°C: 8.5–9.5 m²

Mixing

• Mix resin (105) and hardener thoroughly for two minutes or longer at low temperatures.
• Scrape sides and bottom of the container during mixing to ensure homogeneity.
