1. Chemical structure and cross-linking reaction:
The chemical structure of HAA curing agent contains hydroxyl and amide groups, which can undergo rapid cross-linking reaction with carboxyl groups in polyester resins, increase the curing speed and enhance the physical and chemical properties of the coating. With the high reactivity of Polyester Resins For HAA Based Formulations, HAA curing agent can cure quickly at a lower temperature, ensuring the stability and durability of the coating in outdoor environments.
2. Low toxicity and safety:
HAA curing agent has low toxicity and irritation. Compared with traditional TGIC curing agent, Polyester Resins For HAA Based Formulations improves the safety of the production process and makes it more environmentally friendly and health-oriented. High reactivity enables HAA curing agent to cure quickly at a lower temperature, reducing energy consumption and production costs, which is of great significance for industrial applications.
3. Performance of different types of Polyester Resins For HAA Based Formulations:
According to the data in the above table, different types of polyester resins have different curing times, glass transition temperatures, and properties when using HAA curing agents. For example, YZ9848 polyester resin can be cured in 12 minutes at 165°C, showing the characteristics of low-temperature rapid curing; while YZ9869 polyester resin can be cured in 10-12 minutes at 180°C, showing the characteristics of fast curing speed. These data show that the high reactivity of HAA curing agent enables different types of polyester resins to exhibit excellent performance during the curing process.
