Product Description

C7h6o2 Phenol Formaldehyde Resin for Coated Sand
 
Phenolic resin has good acid resistance, mechanical properties and heat resistance, and is widely used in anti-corrosion engineering, adhesives, flame retardant materials, grinding wheel manufacturing and other industries.
An important application of phenolic resins is as a binder. Phenolic resins are multifunctional and compatible with a wide variety of organic and inorganic fillers. The correct phenolic resin is designed for very fast wetting. And after cross-linking, it can provide the required mechanical strength, heat resistance and electrical properties for abrasive tools, refractory materials, friction materials and bakelite powder.
Water-soluble phenolic resins or alcohol-soluble phenolic resins are used to impregnate paper, cotton, glass, asbestos and the like to provide them with mechanical strength, electrical properties and the like. Typical examples include electrical and mechanical laminate manufacturing, clutch plates and filter paper for automotive filters.


Technical sheet (Coated sand as an example)

Coated sand series products have the characteristics of high strength, low free phenols, fast polymerization and shell resistance. Depending on the characteristics of different castings and products, customers can choose one type for use alone or multiple types for composite use.
