Designed with low viscosity, high mechanical strength, exceptional yellowing resistance, high surface gloss, and robust chemical durability, the Ecure series is widely used in high-end epoxy self-leveling floors, weatherable protective coatings, optical-grade clear encapsulation, stone adhesives, and heavy-duty anti-corrosion linings. All products comply with RoHS and REACH standards.
Product Content / Overview
Developed by Shanghai Feimi Materials, the Ecure Cycloaliphatic Amine Curing Agent Series (Ecure-04, Ecure-08, Ecure-57) is engineered to solve industry challenges associated with traditional aliphatic amines—such as susceptibility to blush/bloom, poor UV color stability, low heat deflection temperature, and brittle cured networks.By utilizing modified cycloaliphatic ring structures, Ecure curing agents deliver remarkable resistance to yellowing, low moisture sensitivity, high glass transition temperatures (Tg), and superior mechanical toughness. They exhibit excelente compatibility with standard Bisphenol A/F epoxy resins and reactive diluents. Featuring low color and high film gloss, they are the ideal choice for premium protective coatings, decorative flooring, optical encapsulation, and structural bonding applications.
Product Advantages

- FAQ
- Q1: Why choose cycloaliphatic amine curing agents over standard aliphatic amines for epoxy flooring and clear topcoats?A: Standard aliphatic amines (such as DETA or TETA) are highly hygroscopic and react with atmospheric humidity and CO2 to form carbamates, resulting in surface blushing, loss of gloss, and yellowing. Cycloaliphatic amines (such as IPDA derivatives in Ecure-04/08/57) possess rigid ring structures that provide vastly superior UV color stability, high surface clarity, moisture resistance, and higher glass transition temperatures (Tg).
- Q2: How do Ecure cycloaliphatic amines perform under low-temperature or humid curing environments?A: Ecure-04 and Ecure-08 are specifically modified to enhance low-temperature reactivity and moisture tolerance. They effectively resist amine blush and surface tackiness even in high-humidity ambient conditions, delivering a smooth, high-gloss finish and complete cure.
- Q3: Does Shanghai Feimi Materials offer sample evaluation and technical formulation support?A: Yes. Shanghai Feimi Materials provides sample kits for lab testing and global B2B evaluations. Our technical support team assists formulators with mix-ratio optimizations, diluent selection, pot-life tuning, and specific property tailoring according to your end-use application.
