Tricyclodecane Dimethanol TCDDM CAS 26896-48-0 / 26160-83-8
Tricyclodecane Dimethanol TCDDM, with CAS number 26896-48-0 / 26160-83-8, is a white crystalline solid. Its melting point ranges from 102 to 106 degrees Celsius. It exhibits excellent thermal stability and is not prone to decomposition at high temperatures, nor does it have a high volatility. A tricyclic rigid aromatic ring framework with two primary hydroxyl groups (-CH₂OH) at both ends, and the rigid ring is the core of its properties.

Application
I. UV Light-Curing Raw Materials
PCB circuit board inks, solder mask inks, photoresists;
3D printing photosensitive resins, UV wood finishes, plastic UV topcoats;
UV coatings for optical lenses, fiber optic coatings.
II. Polyester / Polyurethane Synthetic Raw Materials (Coatings, Resins)
Saturated polyester resins: automotive original equipment paint, sheet coatings, high-end industrial baking paints; three-ring rigid structure improves paint film’s heat resistance, weather resistance, scratch resistance, chemical resistance, and does not powder or yellow over time outdoors.
Water-based polyurethane PU: high-end synthetic leather, fabric coatings, adhesives, ink resins; enhance PU hardness, hydrolysis stability, and low-temperature toughness.
Alkyd resins, high-solid content eco-friendly coating resins.
III. Environmental-friendly Plasticizers, Flavoring Intermediate
Produced by esterification with fatty acids to produce environmentally friendly cold-resistant plasticizers, without phthalates, used for food-contact plastics, PVC medical products, and rubber-plastic cold-resistant modification; replace DOS and DOP.
Synthetic high-end cycloaliphatic fragrance esters (tricyclic decane carboxylic acid esters), raw materials for daily chemical fragrances, fixatives.
IV. Optical, Electronic Special Materials
Optical polyester / polycarbonate modified monomers: high transparency, low birefringence, raw materials for spectacle lenses, light guide plates, optical lenses;
Electronic potting resins, liquid crystal matching resins, precision device packaging materials; excellent dimensional stability, low water absorption rate.
