Natural resins are substances that are secreted by certain plants in response to environmental factors. These resins are used for a variety of purposes, from providing materials for traditional crafts to providing sealants for various surfaces. The most common natural resins examples include rosin, dammar, tree sap, and copal.

Rosin, also known as colophony or pine resin, is a yellowish or brownish sticky solid material that is derived from sap of certain conifer trees. It is used as a glue or sealant, as a surface coating, and as a base for making varnish and other finishes. It is also used in manufacture of rubber, paints, and paper.

Dammar is a type of tree resin that is secreted by Dipterocarpaceae family of trees. It is a dark brown or black solid material that is used in manufacture of paints, varnishes, lacquers, and other finishes. It is also used as a preservative for some natural fibers, as well as a sealant for pottery surfaces.

Tree sap is a clear, sticky substance that is secreted from bark of certain trees. It is typically used as a waterproofing agent, to protect surfaces from moisture and water damage. In addition, some cultures use tree sap to make natural dyes and inks.

Copal is a type of tree resin that is secreted by Protium family of trees. It is a light brown or yellowish solid material that is used as a base for varnish, lacquer, and other finishes. It is also used as a protective coating on wood and other materials.

These are just a few of natural resins that are available. There are many other naturally derived resins, such as kauri gum, amber, frankincense, and myrrh, that are used in a variety of applications. All of these natural resins are derived from plants and are used for a variety of products, from traditional crafts to modern finishes.
