GEOPOL – ecological geopolymer-based inorganic binder system

Self-hardening mixtures curable with SA series hardeners:

• High bonding ability, binder dosage 1.4 to 2.0 %.
• Ecological and economical system for producing moulds and cores.
• Mixture workability of 2 to 90 minutes.
• Good break down after pouring.
• Mechanical reclamation – mechanical abrasion can be used.
• Operational use of 100% recycled sand for backing sand.
• Operational use of 70 to 75% recycled sand for facing sand.

Curing by Hot Air:

• High strength, the ability to produce complex cores.
• Good shelf life of cores without the need for storage in special conditions.
• Possibility of low dosing of binder and additive at high strength.
• No cores deformation.
• Very good disintegration after casting, especially for aluminum castings usually better than for organic binders PUR cold box amine. Reduction of decoring time.
• It is not prone to gas holes and veinings on castings.
• The binder system is environmentally friendly.

Mixtures curable with CO2:

• Binder dosage of 2.3 to 3.0 %.
• Ecological and economical system for producing moulds and cores.
• Mixtures suitable for manufacturing cores by shooting.
• Good break down after pouring.
• Low CO2consumption.
• Seamless core storage life.
