TTA27: 1,2:5,6-Diepoxyhexahydro-4,7-methanoindan Cas 81-21-0

TTA27 (dicyclopentadiene epoxide) is a typical cycloaliphatic epoxy resin. Its molecular structure is characterized by a close bicyclic structure between two epoxy groups and a stable methylene bridge across the six-membered ring. Therefore, the cured product of TTA27 has the characteristics of high crosslinking density, strong rigidity, high heat resistance, strong weather resistance, UV resistance, and self-extinguishing in case of fire. It is especially suitable for outdoor using and radiation conditions.

Application of Tetra TTA27 (Cas 81-21-0)
Coating
The product containing a partial epoxy group can be prepared by condensation TTA27 with unsaturated fatty acids (such as dehydrated ricinoleic acid, linseed oleic acid, soybean oleic acid, tung oil acid, etc.), and then cure it under the action of catalysts BF3 and SnCl4. The obtained coating has excellent UV resistance and alkali corrosion resistance, as well as good hardness and toughness.

Epoxy Castable
The physical, mechanical, and thermal aging properties of maleic anhydride-cured TTA27 and epoxy resin E44 castables are shown in the table below.

Composites
Bisphenol A epoxy resin E51 can effectively improve the mechanical properties of TTA27 composites.

High Temperature Resistant Adhesive
TTA27 adhesive has common bonding strength at medium and low temperatures, TTA27 adhesive shows very good bonding strength when the temperature increases, especially above 150 ℃, so it can be used as a high temperature-resistant adhesive.

Material Tetra has been positioned in high-end epoxy resin since its establishment. As one of the famous cycloaliphatic epoxy resin manufacturers in China, after more than 15 years of development, the company has formed a series of technical systems with independent intellectual property rights.
