Epokisi-poliyamidi nɔrɔnanw, minw dilanna ni epokisi rɛziniw ye, asidi gɛrɛgɛrɛw ka karibɔni cakɛda janw be sɔrɔ u la, o be na ni fɛɛn kɛnɛman ye min ka gwɛlɛ nka min tɛ -tiɲɛ. U ɲagamicogo man gwɛlɛ, u be se ka to daga kɔnɔ ani u kɛli ka nɔgɔ. U be nɔrɔli barikaman yira, u be nɔrɔli ɲuman yira nɛgɛw ni nɛgɛw fanba la minw tɛ-nɛgɛw ye.

Poliyamidi kɛnɛyalifɛnw minw girinya ka dɔgɔ-molɛkili-, olu be to ka kurakuraya, u suguw be sɔrɔ i n’a fɔ u ka gɛrɛntɛ ka dɔgɔ, u be gwɛ, u be furakɛ joona, u be nɔrɔ kosɔbɛ, ani u be sɔrɔ jii la. Dɔw be se ka sɔgɔli fanga sɔrɔ min ka ca ni 10 kN/m ye epokisi nɔrɔnanw kama, o min ka ca ni alifatiki amini kɛnɛyalanw siɲɛ duuru ye.
