Description
A solid or semisolid amorphous organic material. Resins are usually high molecular weight materials that fracture conchoidally. Natural resins are clear to translucent brown exudates obtained from trees or insects, such as Copal, Rosin, Sandarac, Mastic, Dammar, or Shellac. Most natural resins are soluble in alcohols, ethers, and Carbon disulfide, but insoluble in water. They are used in varnishes, inks and adhesives. Synthetic resins, or polymers, are formed by a chemical reaction between two or more substances. Examples are acrylics, alkyds, vinyls, epoxies, polyesters, polyolefins, phenolics, Polystyrene, and Cellulose acetate. Synthetic resins are used in plastics, paints, textiles, and adhesives.
Synonyms and Related Terms
résine (Fr.); resina (Esp.; Port.; It.);
Risks
Combustible with a strong yellow flame and sooty smoke.
Physical and Chemical Properties
Insoluble in water. Most natural resins are soluble in alcohols, ethers and carbon disulfide.
