Attributes of New Furan Technology
• New furan acid cured technology
– Application & solution focused
– To meet specific metallurgical needs
– To meet morestringent EH&S standards
– A furan with reactive components & additives
furan with reactive components additives
• Improve the deficiencies in furan no-bake system
– Worktime / Striptime ratio
–Through-cure
h
– Strength development post strip
– Eliminated or reduced phenol / formaldehyde odors
– 50% reduction in sulphur dioxide / pouring odors
– Reduce sulphur related defects
– Higher use ofrenewable resources
use of renewable resources
– Combined with coatings for max performance
