BECKOPOX™ VEH 2177W/80WA

BECKOPOX™ VEH 2177w/80WA is an aliphatic polyamine adduct primarily used as a curing agent for solid epoxy resin dispersions or emulsified liquid resins. Here are the key details:

Type:

• Aliphatic polyamine adduct

Form of Delivery (f.o.d.):

• 80% in water (80WA), also containing 5% isopropanol
• Hydrogen equivalent weight (f.o.d.): 175 g/mol (solid matter: 140 g/mol)

Product Data (Typical Properties):

• Dynamic Viscosity: 7000 - 12000 mPa.s (100 1/s; 23°C)
• Amine Value: 200 - 230 mg KOH/g
• Iodine Colour Number: <= 10
• Density: Approximately 1.10 g/cm³ (20°C)
• Flash Point: Approximately 48°C

Special Properties and Use:

• Used with solid epoxy resin dispersions or emulsified liquid resins.
• Suited for formulating coatings for mineral substrates, offering fast drying, abrasion resistance, and chemical resistance.
• When used with specific coating systems, offers excellent water and salt spray resistance.
• Rapid film curing at room temperature or forced drying at elevated temperatures.

Mixing Ratio and Pot Life:

• Processing time of approximately 2 - 2.5 hours at 23°C for a specific blend.

Storage:

• Storage stability at temperatures up to 25°C packed in original containers is at least 365 days.
• Synthetic resins containing water may freeze or become inhomogeneous below 0°C, requiring extended heat treatment for regeneration.

Distinguishing Features:

• More reactive than Beckopox EH 623w.
• Suited for coatings on mineral substrates, especially when used with Beckopox EP 384w.

Safety at Work and Environmental Protection:

• When handling and processing, local authorities' rules and regulations for epoxy resins and hardeners should be observed.
• Material Safety Data Sheet is available on request.

Overall, BECKOPOX™ VEH 2177w/80WA is a versatile curing agent suitable for various coating applications, offering fast curing, abrasion resistance, and excellent performance on mineral substrates.
