Phenolic Urethane No-Bake Resin
Self-hardening phenolic urethane resin is specially designed to meet the demands of efficient and large-scale production on self-hardening sand molding lines. It is suitable for casting steel, iron, and non-ferrous metals, offering excellent adaptability across various foundry applications.
This binder system consists of three components:
Component I: Benzyl ether phenolic resin solution
Component II: Polyisocyanate solution
Component III: Catalyst
The curing time of this fast self-hardening phenolic urethane resin system is adjustable between 30 seconds and 2 hours, providing great flexibility for different molding requirements. The usable working time of the sand can reach up to 75% of the demolding time, allowing for efficient production scheduling and better control over the molding process.
In addition, the phenolic urethane resin for casting sand exhibits excellent flowability, making it ideal for both small batch operations and large-scale, continuous casting production. This ensures consistent quality and productivity across a wide range of casting scenarios.
Features
• High strength enables reduced phenolic urethane resin for casting usage without compromising casting performance.
• Good environmental performance help no-bake phenolic urethane resins improve working conditions at the production site.
• The excellent regeneration properties of phenolic urethane resin for casting enhance the reuse rate of reclaimed sand.
• Self-hardening phenolic urethane resin can effectively address casting cracks and structural defects, ensuring higher casting quality.
