BECKOPOX™ EH 623w/80WA is an aliphatic polyamine adduct used as a hardener for water-reducible coatings on mineral and metallic substrates, as well as hydraulic epoxy mortars. Here are the key points from its technical datasheet:
Type:
- Aliphatic polyamine adduct
Form of Delivery (f.o.d.):
Preliminary Product Information:
- This product is intended for trial purposes only and may undergo deviations during transfer into manufacturing in commercial scale.
Product Data:
- Dynamic viscosity: 12000 - 21000 mPa.s at 23°C
- Amine value: 195 - 220 mg KOH/g
- Iodine colour number: <= 10
- Density: Approximately 1.10 g/cm³ at 20°C
- Flash point: > 100°C
Special Properties:
- Used for water-reducible coatings on mineral and metallic substrates, as well as hydraulic epoxy mortars.
Suggested Uses and Processing:
- Used in combination with water emulsifiable liquid resins and other liquid resins to produce water-thinnable paints hardening at room temperature.
- Should be avoided drying at elevated temperatures (> 60°C) to prevent the release of acrylonitrile.
- Can be used in combination with Beckopox EP 128 as an additive for hydraulic mortars.
Mixing Ratio and Pot Life:
- Example blend: 50 g Beckopox EP 147w + 50 g Beckopox EH 623w + 50 g deionized water, with a processing time at 23°C of approx. 2 - 3 hours.
Storage:
- Storage stability in original containers at temperatures up to 25°C 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:
- Beckopox EH 623w is a standard hardener for concrete coatings, while Beckopox EH 613w is especially suited for coatings on metallic substrates and is higher in reactivity.
Safety at Work and Environmental Protection:
- Follow the rules and regulations established by local authorities when handling and processing epoxy resins and hardeners.
- Material Safety Data Sheet is available on request.
