Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of epoxy curing agents, it is recommended to match key technical parameters such as curing temperature and shelf life according to the application scenario (such as coatings, composite materials, or adhesives) to ensure process compatibility.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable epoxy curing agent supply solutions.
  • When purchasing epoxy curing agents in specific fields such as electronic packaging or anti-corrosion coatings, it is important to verify whether the product's moisture resistance, dielectric properties, and other parameters meet industry standards.
  • Different types of curing agents (such as amines and anhydrides) have a significant impact on the curing speed and mechanical properties of epoxy resins. Before procurement, screening should be conducted based on the characteristics of the substrate and the final use.
