Casting resin is generally means phenolic resin and furan resin, usually with amino-containing silane coupling agent to deal with the surface treatment of coated sand with high strength, the key is that the coupling agent of the resin and special intergranular fracture mode changed from attachment fracture to cohesive fracture, indicating that the coupling agent can improve the adhesion of the special sand surface to the resin and make the resin adhere to the surface of the sand more firmly. The bonding efficiency of the resin is fully exerted, and silane can reduce the moisture absorption of core sand, resin to improve the adhesion of the resin, the core sand to improve the strength of many.
