Phenolic Resins Technology Handbook

Until the early 1920, only naturally occurring resins, such as congo kauri gums or shellac were used in the surface coating industry.  Varnish makers combined these resins with oil.  The advent of the hard oil-soluble synthetic resins opened the say to a more scientific approach to varnish making.  The development of synthetic resins for surface coating applications has usually followed the use of similar material in the plastic industry.  One of the first synthetic resins ever used commercially, both in plastics and in surface coatings was the phenolic resin.  Phenolic resins result aldehyde with or without modification.  The present book covers manufacturing processes of phenolic resins.  This book is very useful for new entrepreneurs, technocrats, established units and research scholars.
