How is Polyaspartic Resin Different from Epoxy Resin?

Despite both being resins, polyaspartic resin and epoxy resin are distinct materials.

1. Structural Differences: Polyaspartic resin, an aliphatic compound with amino-active groups, derives its name from its unique aspartic acid structure, typically existing in a liquid state. Epoxy resin, more commonly known, is a type of polymer containing multiple epoxide groups and belongs to the aromatic family. It can be either liquid or solid.
2. Different Curing Agents: Polyaspartic resin requires isocyanate esters for curing, commonly using specialized isocyanates like HDI and HMDI. Epoxy resins typically use polyether amines, anhydrides, or amides as curing agents.
3. Applications: Both exhibit strong adhesion and wear resistance and are used in flooring, waterproofing, and coating applications. However, polyaspartic resin excels in weather resistance and tensile strength, making it more suitable for outdoor flooring and waterproofing. Epoxy is often used for indoor flooring and corrosion protection. In the adhesive sector, including beauty sewing agents, polyaspartic resin, with its superior weather resistance, outperforms epoxy in resistance to yellowing.

Feiyang's Polyaspartic Resin Production

Feiyang manufactures polyaspartic resin, serving as a reactive partner for various isocyanates to form a dual-component polyurea/polyurethane transparent coating. This resin blends well with isocyanates, offering more robust and durable surface effects. Their exterior wall coatings are distinguished by weather and yellowing resistance, zero VOCs, requiring less paint application, thus ensuring higher efficiency. The end-users benefit from the rapid drying freedom, easy application with standard equipment, even with high solid content. An additional advantage of using polyaspartic resin is the flexibility to tailor reactivity for batch mixing and application, controlling the curing rate when added to aliphatic coatings, and altering reaction time to extend the application window. Essentially, it's customizable to suit application needs. Detailed information about Feiyang’s polyaspartic resin follows:
