Types of resin
There are three main types of this material: resin gum is produced by distillation of the resin material collected from living trees, and the raw material of the resin is obtained by creating a longitudinal incision through which the resin flows, and the second type is the wooden resin that is extracted from the remaining logs after cutting using The third type is sulfuric resin, also called resin pine oil, a byproduct that lags behind the manufacture of wood pulp.
Usage
Galvanized resin is used in many industrial purposes, and is most commonly used with sodium carbonate to cover paper with colloidal material to prevent paper absorption of moisture, and is used in the preparation of paints, varnishes, adhesives, sealants for insulation purposes, as well as printing inks.
