The relationships among softening point, minimum viscosity and strength were analyzed, indicating a direction for developing high-softening-point, high-strength phenolic resins. Resin-coated sand shell peeling...

Hot-box release agents can be used in resin-coated sand casting, while cold-box release agents can be used in self-setting furan resin sand casting, making release easier and improving efficiency...

A release agent is an interfacial coating applied between surfaces that readily adhere to each other. It helps surfaces separate easily and remain smooth and clean...

Dibutyl phthalate. Formula: C16H22O4. Properties: a colorless, transparent, oily liquid with an aromatic odor; combustible, insoluble in water and soluble in common organic...

1. Introduction. Types and applications: German chemist Baeyer first synthesized phenolic resin in 1872. In 1907, Belgian-American Baekeland proposed heat curing...

Resin-coated sand takes its name from the resin covering its surface. This solid novolac phenolic resin film distinguishes it from hot-box sand, which uses liquid...

This range consists of thermoplastic phenolic resins made by polycondensation of phenol and formaldehyde, with good flow, rapid polymerization, high flexural strength and free...

Alcohol-based coatings are mainly used in resin-bonded and sodium silicate sand casting, usually by brushing or spraying, especially for small and medium castings. No oven drying is required...
