When one talks of the Indian rosin industry, one cannot but talk of the house of dujodwala, the oldest and the largest primary producers of rosin in the private sector in India. From small beginnings with a small scale unit in 1949 for manufacturing rosin and turpentine, the dujodwalas have today emerged as the dominant players in the field of rosins and rosin derivatives, terpene chemicals, synthetic resin, alkyl phenolic resin, pure phenolic resin, foundry resin, ester gum, ketonic resin, polyester resin and camphor.
