Gum Copal

Gum copal, also known as manila copal, is a resin produced by the sap of the forest tree. Its properties of water resistance, solubility in alcohols, ability to give glossy finishing and superior binding abilities makes it an important source of raw materials for the production of varnishes, adhesives, paints and perfumes.

It is known as Sundras, Chandras and Karfa in different parts of our country.

Gum copal has had a extensively used in both past and present times. Mainly used as incense by ancient civilizations, it also found use as an early form of glue, and traditional medicine for cases such as dysentery, stomach pains, dizziness and fright. It was often used in religious occasions, too, in the form of sacrifices to deities (typically designating the copal as food for the gods).
Today, gum copal is generally used as incense. It is also used as a varnish or waterproofing material (when it is heated with certain oils, it becomes nearly transparent). It also can be used as an ingredient in adhesives, perfumes, printing ink, paints and films.  Gum copal is sold primarily two ways. The first way is as powder, which is usually mixed with turpentine to make varnish. The other way is as the natural "rocks" which can then be used in many different ways.


A tape is a strip either of cloth, paper, metal, fiber, and plastic used to bind things together. It is a sticky strip sold in a roll. It is coated with adhesive on one side or both the sides depending on the intended use. It can be used in packaging at home, industry.

Abrasive Products

An abrasive is a material, which is used to shape or finish any stuff through rubbing which leads to part of the substance being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the material which are used to cut, grind and polish other softer materials are known as Abrasives.

Abrasives are extremely common and are used very extensively in a wide variety of industrial, domestic, and technological applications. This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. A coated abrasive is an abrasive grain bonded to a flexible substrate using adhesives. Common substrates are paper, cloth, vulcanized fiber, and plastic films and come in various grit sizes.

Common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening and sanding.
