Product Abstract / Summary
Shanghai Feimi Materials specializes in the R&D and manufacturing of Fast Curing Modified Aliphatic Amine Epoxy Curing Agents (Ecure Series). Specially engineered for rapid room-temperature curing and low-temperature reactivity, these hardeners provide fast strength build-up, excellent lap shear strength, chemical resistance, and outstanding moisture tolerance. Widely used in fast-setting adhesives, emergency metal repair compounds, anchor bolts, electronic encapsulation, and quick-maintenance industrial coatings.
Product Content / Overview
Developed by Shanghai Feimi Materials, the Ecure Fast Curing Modified Amine Series (Ecure-05, Ecure-28, Ecure-47) is formulated to solve critical industrial challenges such as slow gel times at low ambient temperatures, extended production cycles, and poor adhesion under humid conditions.By chemically modifying aliphatic amine backbones, Ecure hardeners achieve ultra-fast reactivity even at low temperatures (0°C ~10°C) while maintaining low viscosity, high mechanical strength, and excellent chemical resistance. They feature low color, good compatibility with standard Bisphenol A/F epoxy resins, and rapid green strength development. They can serve as primary fast curing agents or speed accelerators for standard amine systems, drastically shortening tack-free time and boosting turnover efficiency for B2B manufacturers.
Product Advantages
- Ultra-Fast Cure & Rapid Strength Build-upSignificantly shortens gel time and tack-free time at ambient temperature, enabling rapid handling strength within minutes and accelerating downstream assembly lines.
- Exceptional Low-Temperature ReactivityMaintains reliable, fast curing capability even under cold conditions (0°C~ 10°C), preventing incomplete curing, surface blushing, or sticky residues during winter applications.
- High Bond Strength & Superior Mechanical ToughnessProvides high lap shear strength (LSS) on metals (steel, aluminum), concrete, ceramics, and engineering plastics, offering durable impact resistance and vibration damping.
- Outstanding Moisture & Chemical ResistanceDemonstrates strong resistance to water, acids, alkalis, salts, and industrial solvents, ensuring reliable long-term performance under demanding humid or outdoor environments.
- Stable Supply & Custom Acceleration ProfileBacked by automated factory production and strict batch-to-batch quality control. Custom gel times, reactivity profiles, and viscosity grades can be tailored to meet your specific application requirements.

FAQ
- Q1: What are the main benefits of using Ecure fast-curing modified amines in low-temperature applications?A: Conventional amine hardeners suffer from extremely slow curing or complete freeze-up in cold weather (0℃), leading to amine blush, surface tackiness, and weak adhesion. Ecure-05/28/47 feature modified active amine structures that accelerate reaction kinetics at lower temperatures, ensuring rapid green strength build-up, tack-free surfaces, and high final bond strength.
- Q2: Can Ecure fast curing agents be blended with standard amine hardeners as cure accelerators?A: Yes. Ecure series hardeners possess excellent compatibility with standard polyamide, cycloaliphatic, or polyetheramine curing agents. Formulators can add 10%–30% Ecure as a reactive accelerator to adjust pot life, speed up cycle times, and improve low-temperature curing without causing phase separation.
- Q3: Does Shanghai Feimi Materials support customized gel times and tailor-made formulations?A: Absolutely. Shanghai Feimi Materials maintains an expert R&D team and application laboratory in fine chemicals. We offer sample testing, technical selection guidance, and custom formulation services to tailor gel time, viscosity, and curing profile according to your specific processing equipment and temperature conditions.
