Structural Formula:

Physicochemical Properties：

At room temperature, it is a colorless, highly viscous liquid with a slight, characteristic odor. It is miscible with common polar organic solvents and partially soluble in water, aliphatic, and aromatic hydrocarbon solvents.

Properties and Uses：

This compound is mainly used in the synthesis of polymers such as polyacrylates, polyesters, epoxy resins, and polyurethanes. These resins are used in varnishes and coatings, exhibiting good adhesion, high tensile strength, heat resistance, weather resistance, and impact resistance; they are also used in low-viscosity adhesives, sealants, and molding compositions. This special diol can also be used to synthesize photosensitive materials with high photosensitivity, high transparency, light resistance, and dry etching resistance; to synthesize high-refractive-index plexiglass; and to synthesize dental materials with high transparency and strength. TCD-based tricyclic diol diacrylate photocurable fiber optic resins exhibit excellent heat resistance, moisture resistance, and rapid curing performance. Epoxy resins based on this diol have high flexural and peel strength, hardness, and very low water absorption. It can also be used as a fixative in the fragrance industry, as a halogen-free immersion oil for microscopes with excellent optical properties, and can be used to synthesize lubricants.

TCD-based polyurethanes possess high adhesion, strength, modulus, and a high glass transition temperature.
