The additive is mixed with the core sand and thuscontributes to reducing expansion and penetration defects. Aftercore breakdown, ANTRAPEX ® passes into the moulding materialwhere it has a positive effect on the casting surface and sandstability. The amount of adhering moulding sand is also minimised.Double benefits: The effects of ANTRAPEX ®The doubly positive effect of ANTRAPEX ® gives it a significant lead over conventionalcore sand additives.CastingReduction in expansion andpenetration defects in the coreHighly effective lustrous carbonformer in the moulding sandThe productsANTRAPEX ® P is a blend of synthetic organic and inorganic components.The core sand additive has been developed by S&B especiallyfor the PUR Cold Box process.ANTRAPEX ® M is a pure mineral-based inorganic additive. It is applicablefor the PUR Cold Box process as well as for the core productionin the Hot Box and Warm Box processes.The S&B service includes customer-specific product variants ofANTRAPEX ® . This means that we offer modified additives individuallyaligned to the core making requirements of the foundry concerned.Your benefitsANTRAPEX ® facilitates the production of high-quality castings:• Casting surfaces of near-perfect finish• Significantly reduced expense in terms of finishing work and corecoating operations• Excellent compatibility with the moulding sand after core breakdown• Good recyclability, minimum pollution burden• Significantly reduced gas formation in the core compared with additivesbased on wood flour3
