Damar resin

Types of Damar Resin

Incorporated into varnishes, typecasting plaster, and as a source of oil of turpentine, damar resin comes in various types. They include:

• White Damar

  White damar resin comes from the Shorea javanica tree, which mainly grows in Java, Indonesia. The tree produces clear, translucent resin, which is often brittle and breaks into glassy shards. We noted that white damar is prized for its purity and is often used in high-quality varnishes, especially for oil paintings. In painting and restoration, it is also a preferred medium since it dries clear and is doesn’t yellow.

• Star Damar

  Star damar engages in gum extraction from several trees in the Styrax family, such as Styrax benzoin. It is distinguished by its star-shaped crystal forms and is usually dark amber in color. Since it has a stronger aroma and is richer in certain acids compared to other damars, star damar is commonly used in incense and traditional medicine. Furthermore, it can also be used in varnishes, but often in lower quality compared to white damar.

• Red Damar

  Red damar originates from the resin of trees in the Shorea genus, such as Shorea robusta, and is often mixed with other resins or has a higher wax content. Both the color and consistency vary widely, often being darker and more opaque than other damars. Red damar’s density can make it slower to dry when used in paints or varnishes. Nonetheless, it is often used in lower-grade varnishes and in local art for pigments.

• Yellow Damar

  Yellow resin primarily comes from the Dipterocarpus tree species and is commonly collected in Malaysia and parts of Indonesia. It often contains more natural oils and waxes, giving it a more opaque appearance. Yellow damar is a less pure form of resin and is favored in local crafts and industries. In addition, it is used as a binding medium in traditional paints.

• Burmese Damar

  We noted that Burmese damar is extracted from multiple species of Dipterocarps in Myanmar (Burma), such as Dipterocarpus alatus. It’s similar to white damar, but often has a darker tint and is less transparent. Burmese damar is still used in varnishes and paints, but its resin quality can vary depending on the tree species.

Industrial Applications of Damar Resin

Damar resin is valued in multiple industries for its unique properties. Here are some of its applications:

• Varnishes and Paints

  Damar resin’s ability to dry quickly and form a hard, clear finish makes it ideal for varnishes, especially in oil paints. When mixed with oil or alcohol, damar resin creates a varnish that is clear, glossy, and protective. This makes it a popular choice among artists for preserving paintings while retaining their original colors.

• In Woodworking

  Damar varnish is used in woodworking to produce a protective layer on wooden surfaces. Its clear and glossy finish allows the natural beauty of the wood to show while protecting it from moisture, dust, and UV light. Varnished furniture, musical instruments, and decorative wood pieces maintain their aesthetic appeal and durability for longer, especially in artistic contexts.

• Adhesives

  In traditional and modern applications, damar resin is used as an adhesive. When heated, the resin becomes sticky and is used to bond materials together, like wood or porous surfaces. It’s also used in repairing ceramics and inlay work, where artisans need a glue that hardens solidly and invisibly. Its resilience and water resistance allow for durable and reliable repairs.

• Incense and Medicinal Products

  Damar resin, particularly in the form of red or star damar, is used extensively in incense. When burned, it releases fragrant smoke that has calming and purifying properties. This is especially popular in meditation and religious practices. In lesser cases, damar is included in traditional medicines. Here, it is believed to have multiple healing properties like anti-inflammatory and antiseptic effects.

• Papermaking

  Damar resin is used as a rosin size in paper manufacturing. The resin helps fill the paper’s fibers, giving it a smooth finish and enabling it to resist ink and moisture. This application is critical in producing high-quality printing papers. They have a polished look that allows crisp, clear text and images without ink bleed or absorption.

• Traditional and Modern Art Goods Manufacturing

  Damar resin is valued in both traditional crafts and modern manufacturing. For instance, in traditional batik or local paintings, yellow damar acts as a binding medium that mixes with pigments to produce vibrant, long-lasting colors. In contemporary art materials, damar varnish is used by artists to create protective, glossy layers over their paintings. In this case, damar resin is especially popular in oil painting. This is because it increases flow dynamics and reduces the paint’s tendency to crack.

These are the features of damar resins:

• Color: Damar resin ranges from clear and translucent to amber or opaque depending on its type.
• Appearance: It usually occurs in brittle, glassy fragments or yellowish beads. Occasionally, the resin may be in chunks or blocks.
• Odor: Freshly broken damar has a faint, pine-like aroma. On the other hand, older pieces may lose fragrance and take a dull color.
• Taste: It is bitter and slightly sweet with a resinous, pine-like flavor.
• Solubility: Damar resin is soluble in organic solvents like alcohol, ether, and essential oils.
• Melting Point: The resin melts at a temperature range of 100-120 °C (212-248 °F). This tends to vary slightly depending on the resin type and purity.
• Chemical Composition: Damar resin is composed of terpenes such as damasene and b-caryophyllene. It also contains acids like abietic acid, which are typical in many natural resins.

How to Use

• Art and Restoration

  Artists and restorers typically mix damar resin with solvent components like turpentine or alcohol to create a varnish. When used in painting, damar resin mixed with a medium produces a glossy, transparent paint layer. This enhances the paint's depth while safeguarding it. In restoration, varnish reestablishes the painting's protective layer and appears as a retouched surface.

• Wood Finishing

  In woodworking, damar varnish is applied using a brush or cloth like any other varnish. It’s generally prepared by dissolving damar resin in turpentine or paints through a heat process. Artisans create a protected wooden finish which highlights the wood's beauty and acts as a protective barrier against moisture and wear. Moreover, when mixed with other damar resin and varnish types, damar resin can create a unified and polished juxtaposition of various woods in complex designs.

• Craft and Repair

  In crafts, the resin is typically heated and applied as a glue. This binds materials like wood or porous surfaces together. Crafters use it to repair items such as ceramics by combining adhesive properties with its capacity to restore aesthetic appeal. Crafters rely on its ability to produce solid repairs that are seamless and keep the items’ looks intact.

• Incense and Aromatherapy

  Users typically burn damar resin alone or mixed with other ingredients to create incense. This is mainly for meditation or religious purposes. In aromatherapy, it purifies spaces and provides relaxation. Moreover, temple and ritual incense gives users a spiritual and calming atmosphere. Burning resin releases smoke that calms the user. This lets them clear their space of negative energy.

Maintenance and Care

Proper maintenance ensures longevity and consistent performance when using damar products:

• Storage

  Users should keep damar resin varnish in a cool, dark area where it won’t solidify or deteriorate due to excessive heat or light exposure. Further, they should seal containers tightly to prevent air contamination. This can lead to resin forming a hard crust on its surface. It’s also important to ensure that damar varnish is isolated from direct sunlight. Prolonged exposure to sunlight may degrade the resin and affect its protective qualities.

• Tools Cleaning

  Users should clean any tools or brushes used with damar varnish immediately after use. They can do so with solvents like mineral spirits or turpentine. This prevents damar resin from hardening on the more difficult to remove surfaces of the tools. During cleansing, brushes can be soaked in solvent to release varnish deep within the bristles. This prolongs the brush’s life.

Quality Considerations of Damar Resin

Buyers should consider a few aspects to ensure they get high-quality Damar gum. They include:

• Purity

  High-quality damar resin is typically pale in color or clear and has a transparent appearance. To identify this, buyers should avoid resin mixed with other substances or impurities which makes it darker and less translucent. Manufacturers of pure resin often label their products accordingly.

• Type

  Different damars are suited for various functions. For instance, white damar is used in high-quality varnishes and art restoration. On the other hand, red and yellow damars are ideal for incense or local crafts due to their heavier density. Buyers should choose the appropriate type depending on their use requirements. They should also ensure that the resin is sourced from reputable suppliers who use correct harvesting methods. This preserves the quality and integrity of the resin.

• Smell

  High-quality damar resin is usually fragrant with a pine-like aroma. Buyers should avoid any resin that has little or no smell. It’s often a sign of low-quality or old resin that has lost its essential oil content. Strong, natural fragrance indicates that the resin is fresh and full of natural oils. These are excellent for various applications.

• Consistency

  Buyers should get resin that usually breaks into brittle pieces or shatters like glass. It is a feature of high-quality damar gum. This resin typically dissolves easily in alcohol or turpentine to form a uniform mixture without any sediment at the bottom. When resin is of low quality, it forms clumpy mixtures that settle at the bottom or do not dissolve consonantly.

• Testing

  Buyers can do several tests to confirm resin quality. For instance, they can burn a small piece of resin and check the smoke. Pure damar resin burns with a clean flame and minimal ash. The residue is often sooty with low-grade resin. They can also dissolve a small sample in alcohol. Pure damar resin dissolves entirely without residue formation. This makes a clear solution. Affected resin mixtures are unable to dissolve completely or leave a gritty texture behind.

Q&A

What is damar resin made of?

Buyers should note that damar resin is sourced from the gum produced by specific trees in the Shorea and Dipterocarpus. It mostly grows in Southeast Asia’s tropical forests. The trees exude resinous sap as a healing mechanism when the bark is injured or harvested. This sap then hardens into what is commonly known as damar resin over time.

What is the difference between damar and copal resin?

Damar resin primarily comes from trees in the Shorea and Dipterocarpus families. Conversely, copal resin is extracted from various tree species. These include the Boswellia tree, which produces frankincense, and the Commiphora tree, which produces myrrh. Damar resin is usually clear and more brittle when broken. On the other hand, copal resin is often cloudy and less brittle. It tends to be softer and stickier than damar resin.

Is damar resin toxic?

Damar resin is generally regarded as safe for most purposes. These include incense burning, art materials, and traditional medicine. Nevertheless, a small number of people may experience skin irritation, respiratory reactions, or allergies upon exposure to the resin or its smoke. It’s worth noting that damar resin is primarily exuded by trees in the Shorea and Dipterocarpus genus. These trees are commonly found in tropical regions of Southeast Asia.

Is damar antifungal?

When burned or applied topically, damar possesses several beneficial properties, such as antifungal, antimicrobial, and anti-inflammatory properties. These are mainly due to the terpenes and other bioactive compounds it contains. The resin has historically been used to treat infections, promote wound healing, and inhibit fungal growth. Recent studies confirm the resin has potential antifungal activity against numerous fungal species.
