Resins Cured by Carbon Dioxide Gas
ALKAFEN™
ALKAFEN™ resin system is alkaline phenolic binders that allow preparing fast hardening cores and molds with CO₂ gas.
Thanks to low emission values during core preparation and casting, ALKAFEN™ resins become eco-friendly in cold box core systems.
Product Advantages
- Suitable for fast and high efficient production
- Enables high strength cores production
- Nitrogen, sulphur or phosphorus free
- Environmental and user friendly via low emission value
- Easy clean-up with water
The strength performance of ALKAFEN™ resins, which have been specially developed to resist to environmental conditions such as temperature and humidity, continues to increase in the following hours after the gassing process. ALKAFEN™ resins can be specially modified and developed with the desired for customer’s requirements. As a result of innovative research, ALKAFEN™ resins are used for all casting.
Ideal Usage Guide
Addition of 2.5 % resin to 45-50 AFS silica sand and after 10 to 60 seconds of gassing process depending on the particle size to show optimum performance. After gassing with CO2, cores reach to 100 – 200 N/cm² bending strength.
