Renaissance beauty ® AM-641 is used as a pure polyester powder coating beta hydroxyalkylamide curing agent, the same performance with the international well-known brand PrimidRXL-552. Compared with TGIC should be the main characteristics of resistance to beauty ® AM-641 is environmentally friendly and so it is not necessary a toxic signs; in addition also has the advantages of less dosage, low price, at the same time, low curing temperature, stable quality and good storage property, it is recognized as the most promising alternative to TGIC a.
