Dammar gum

Natural resin obtained from trees of the family Dipterocarpaceae

Dammar gum is a natural resin obtained from trees of the family Dipterocarpaceae, primarily from the genera Shorea, Balanocarpus, and Hopea. It is commonly used in the production of varnishes, as well as in traditional medicine and food applications.

Etymology

The term "dammar" is derived from a Malay word meaning "resin" or "torch made from resin". This reflects the traditional use of dammar gum in Southeast Asia, where it has been used for centuries as a source of light and as a sealant.

Production

Dammar gum is harvested from the trees by making incisions in the bark, which allows the resin to exude and harden upon exposure to air. The hardened resin is then collected and processed for various uses. The primary regions of production include Indonesia, Malaysia, and India.

Properties

Dammar gum is known for its clear, pale yellow appearance and its ability to form a glossy, durable film. It is soluble in turpentine and other organic solvents, making it ideal for use in varnishes and as a component in oil painting mediums.

Uses

Varnish

Dammar gum is widely used in the production of varnishes due to its ability to produce a clear, glossy finish. It is often used in the restoration of oil paintings and as a protective coating for various surfaces.

Traditional Medicine

In traditional medicine, dammar gum is used for its purported health benefits. It is believed to have anti-inflammatory and wound-healing properties, and is sometimes used in the treatment of respiratory ailments.
