U-CAT 410 is A low curing temperature bisphenol A type epoxy resin curing agent. It is a clear, colorless liquid with a slight odor. U-CAT 410 is compatible with a variety of epoxies and can be used to produce high-performance composites with good mechanical properties.

Physical and chemical properties

· CAS Number: 1333-74-0

· Molecular formula: C18H24O2

· Molecular weight: 276.36 g/mol

· Density: 1.12 g/cm ³

· Boiling point: 215°C

· Flash point: 100°C

· Refractive index: 1.525

· Solubility: Soluble in acetone, ethyl acetate, tetrahydrofuran

Method of making

U-CAT 410 is produced by the reaction of bisphenol A with epichlorohydrin. The reaction takes place in the presence of a base catalyst such as sodium hydroxide. The reaction produces a mixture of different epoxies, which are then separated by distillation.


U-CAT 410 is used as a curing agent for epoxy resins. It is often used in combination with hardeners, such as 4,4′ -diaminodiphenylmethane (DDM). The epoxy and hardener are mixed together and then cured at 100°C or higher. The curing process produces a strong and durable composite material with good mechanical properties.



· Low curing temperature

· Compatible with a variety of epoxies

· Produce high performance composite materials with good mechanical properties

Preventive measures

· U-CAT 410 is a skin irritant that can cause respiratory problems if inhaled.

· Always wear gloves and a respirator when using U-CAT 410.

· U-CAT 410 should be stored in a cool, dry place.

· U-CAT 410 is a hazardous waste and should be disposed of properly.
