Description

Sandarac is a natural resin derived from the *Tetraclinis articulata* tree, valued for its excellent film-forming properties and pale color. This high-quality resin is essential for creating durable, glossy varnishes and protective coatings with superior clarity. It serves as a critical raw material for industries including fine art conservation, specialty lacquers, and traditional incense manufacturing, where material purity and performance are paramount.

Application

• Fine Art Varnishes & Conservation: A primary component in high-grade picture varnishes for oil paintings, providing a reversible, protective, and non-yellowing finish.
• Specialty Lacquers and Coatings: Used in formulations for musical instruments, antique furniture restoration, and decorative objects requiring a hard, brilliant polish.
• Incense and Perfumery: Employed as a fragrant fixative and binder in the production of traditional incense sticks and resinoid perfumes.
• Printing Inks and Lithography: Acts as a hardening agent and gloss improver in specialty printing ink formulations.
• Dental and Surgical Varnishes: Historically used in certain protective dental cements and surgical dressing formulations.
• Adhesives and Sealants: Imparts specific tack and durability properties in niche adhesive applications.
