1. Chemical properties

 

  • 2. Application areas

     

    • Epoxy resin curing acceleration:
      • In epoxy resin systems, DMP-30 is widely used as a curing accelerator. It can significantly speed up the reaction between epoxy resins and various curing agents such as acid anhydrides, dicyandiamide, and phenolic resins. For example, in the production of epoxy coatings, adhesives, and casting resins, adding an appropriate amount of DMP-30 can reduce the curing time and lower the curing temperature, which is beneficial for improving production efficiency and reducing energy consumption.
      • In the case of epoxy-acid anhydride curing systems, DMP-30 can catalyze the reaction between the epoxy groups of the epoxy resin and the carboxyl groups of the acid anhydride, promoting the formation of a cross-linked network structure.
    • Composite materials:
      • When preparing epoxy-based composite materials (such as glass fiber-reinforced composites, carbon fiber-reinforced composites), DMP-30 can be used to adjust the curing process. It helps to ensure that the epoxy resin matrix cures uniformly and quickly around the reinforcing fibers, enhancing the mechanical properties of the composite materials, such as strength and toughness.
    • Electrical insulation materials:
      • In the production of electrical insulation products like electrical insulators, transformer insulation components, and electrical encapsulants made of epoxy resin, DMP-30 plays an important role in accelerating the curing process. This ensures that the final products have good electrical insulation properties and mechanical stability.
    • Adhesive applications:
      • Epoxy adhesives are widely used in various industries for bonding different materials. DMP-30 can be added to epoxy adhesive formulations to make the adhesive cure faster, which is useful in applications where quick bonding is required, such as in the automotive and aerospace industries for bonding metal parts, composites, and other components.

What are the raw materials for polyamide curing agent 3115 and what are their respective proportions?
What are the raw materials for polyamide curing agent 3115 and what are their respective proportions? Polyamide curing agent 3115 is typically synthesized from a dimer of vegetable oleic acid and ethylene amine. But the specific proportion of raw materials is usually a technical secret of the enterprise and is generally not fully disclosed. According to the general synthesis principles and related research of some polyamide curing agents, the raw materials and general situation involved are as follows: -* * Dimer acid compounds * *: such as dimer acids obtained by mixing one or more of soybean oil fatty acids, cottonseed oil fatty acids, rapeseed oil fatty acids, tall oil fatty acids, etc. in any proportion and polymerizing. In the synthesis of polyamide curing agents, dimer acid compounds generally account for a large proportion, possibly around 50% -70% (by weight). -Amine compounds: Common ones include ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine, etc. They are generally used as raw materials for reacting with dimer acids, and form polyamide structures through condensation reactions between amine groups and carboxyl groups of dimer acids. Its proportion may be around 30% -50% by weight. Different manufacturers may make appropriate adjustments to raw materials based on product performance requirements, resulting in differences in the proportion of raw materials.
