Question 1

What is an amine adduct hardener and how does it differ from a straight amine?

Accepted Answer

An amine adduct is a pre-reacted product of a primary amine (such as DETA or TETA) with a small amount of epoxy resin. The reaction caps some of the reactive NH groups, reducing volatility, skin irritation and blushing compared to straight aliphatic amines, while still providing room-temperature cure and good chemical resistance.

Question 2

How do I calculate the correct stoichiometric mix ratio for AW-106 with E-51?

Accepted Answer

Use the formula: phr = (56100 × n) / Amine Value, where n is the average active hydrogen functionality per molecule. For AW-106 the recommended mix ratio is 30–35 phr by weight of hardener per 100 parts E-51 resin. Always verify by small trial mix and adjust ±5% based on the specific pot life and mechanical property target.
