Product Description
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.
Resins In low grade coated abrasives, animal glue is used as the maker coat, but synthetic resins are required where water and heat resistance is required. Although several resin types are used, such as, urea formaldehyde, and epoxy, phenolic resin provides the highest heat and water resistance. Maker coat resins are normally water based, whilst the size coat can be aqueous or solvent borne. Solvent based resins offer the highest performance but special flame proof plant is required. One problem with phenolic resin is their comparative brittleness. Modified phenolic resins, and mixtures of polymers are used for very flexible abrasives. However, modified resins do tend to exhibit reduced heat resistance. Special high water tolerance phenolic resins grades are available with improved compatibility with water borne polymers such as PVA.
