BECKOPOX™ EH 2162W/75WA

Beckopox EH 2162W/75WA is a type of hardener primarily used in concrete coatings. It offers lower viscosity and a longer pot-life compared to standard hardeners like Beckopox EH 623w. This extension of pot-life is particularly noticeable when formulated with lower VOC levels and used alongside liquid EP-resins.

Here are some key details about Beckopox EH 2162W/75WA:

• Type: Aliphatic polyamine adduct
• Form of Delivery: 75% in water (contains approximately 2.5% methoxy propanol)
• Dynamic Viscosity: 1900 - 7200 mPa.s (at 50 1/s; 25 °C)
• Iodine Colour Number: <= 10
• Amine Value: 160 - 210 mg KOH/g
• pH-Value: 10 - 11
• Non-Volatile Matter: 73 - 77%
• Density: Approximately 1.10 g/cm3 at 20 °C
• Flash Point: > 100 °C

Suggested Uses:

• Hardener for water-reducible coatings on mineral and metallic substrates.
• Used in combination with water emulsifiable liquid resins and other liquid resins to produce water-thinnable paints hardening at room temperature.

Mixing Ratio and Pot Life: A blend of 100.0 g Beckopox EP 147w and 116.5 g Beckopox EH 2162W has a processing time at 23 °C of approximately 3 hours. It's important to use the material within the stated time limit as the termination point cannot be visually seen through viscosity increase or gelation.

Storage and Handling:

• Follow local regulations when handling epoxy resins and hardeners.
• Synthetic resins containing water may freeze or become inhomogeneous below 0 °C, but they can be regenerated through extended heat treatment at 40 - 50 °C with continuous stirring. Ensure frostproof storage for such products.

Precautions:

• Lowest storage temperature: -15 °C.

Always refer to the technical datasheet and follow recommended procedures for safe and effective use.
