Cycloaliphatic Epoxy Resin

Cycloaliphatic epoxy resins refer to a series of products obtained by oxidation with butadiene and acrolein as base materials and the mixture of hydrogen peroxide and peracetic acid as oxidant. They have a variety of applications, including 3D printing, coating, ink, adhesives, composites, and electronics, among others.

Cycloaliphatic epoxy resins may be cured by anhydride-based methods as well as UV/EB- and thermally-curable methods.

Types of Cycloaliphatic Epoxide Resins

TTA21: 3,4-Epoxycyclohexylmethyl- 3',4'-Epoxycyclohexane Carboxylate

As the typical cycloaliphatic epoxy resin, TTA21 is most widely used in coatings, inks, adhesives, 3D printing and other fields.

TTA26: Bis (3,4-Epoxycyclohexylmethyl) Adipate

TTA26 has excellent weather resistance and electrical insulation, low curing shrinkage, good heat resistance, low viscosity and good toughness.

TTA3150: Poly[(2-oxiranyl)-1,2-cyclohexanediol] -2-ethyl-2-(hydroxymethyl)-1,3-propanediol Ether

TTA3150 contains very few chloride ions and chloride salts, and has the characteristics of high transparency, high heat resistance, high Tg, excellent weather resistance, and excellent electrical properties.

TTA3150 CE: Mixture of TTA3150 & TTA21 (TTA3150CE)

Mixture of TTA3150 & TTA21.

TTA27: 1,2:5,6-Diepoxyhexahydro-4,7-methanoindan

TTA27 is characterized by a close bicyclic structure between two epoxy groups and a stable methylene bridge across the six membered ring.

TTA28: Tetrahydroindene Diepoxide

TTA28 is characterized by the saturated double cycloaliphatic epoxy structure without ester bond, small molecular weight and extremely low halogen content.

TTA11: 4-Vinyl-1-Cyclohexene 1,2-Epoxide

TTA11 contains a double bond structure which can be used for hydrosilation in the synthesis of cycloaliphatic epoxy resins containing siloxane segments.

TTA15: 3 4 Epoxycyclohexylmethyl Methacrylate

This product is an epoxy acrylate resin with a saturated alicyclic structure.

TTA16: 3,4-Epoxycyclohexylmethyl Acrylate

TTA16 does not contain methyl group, and the acrylate resin generated after participating in the synthesis reaction has better reactivity performance than TTA15.

TTA22: 1,2-Epoxy-4-epoxyethylcyclohexane

TTA22 is a kind of cycloaliphatic bisepoxide, which can react with anhydride, amine, and other curing agents.

TTA800: (3,4,3',4'-dicycloxyl) Bicyclohexane

TTA800 has excellent heat resistance, high electrical insulation property, high cation reaction activity, low viscosity, and high transparency.

Advantages of Cycloaliphatic Epoxy Resin



The cycloaliphatic epoxy resin has strong dilution ability. There will be an obvious dilution effect when the addition amount in the formula exceeds 20%.

The glass transition temperature (Tg) of cycloaliphatic epoxy resin TTA21P(3 4 Epoxycyclohexylmethyl- 3',4'-Epoxycyclohexane Carboxylate Cas 2386-87-0) is 204 ℃, much high than the other common epoxy resin.

The cycloaliphatic epoxy resin TTA21 has excellent adhesion on a variety of substrate surfaces.

The figure shows that the volume shrinkage of cycloaliphatic epoxy resin after UV curing is significantly lower than that of acrylate.

When 20% of the cycloaliphatic epoxy resin is added to the formula, the product has played a very positive role in overcoming oxygen polymerization inhibition.

Compared with bisphenol A epoxy, cycloaliphatic epoxy has little difference between the dielectric constant and dielectric loss at room temperature but the difference is obvious at high temperature. It has obvious advantages in the application field of insulating castable, such as insulation epoxy.
