F220: A Fast-Curing Polyaspartic Resin with 5-Minute Touch-Dry Performance

Product Specification

In industrial protection, anti-corrosion, waterproofing, and high-performance coatings, manufacturers are often looking for the same key benefits: faster drying, tougher coating films, lower VOC, and longer service life.
FEISPARTIC F220 polyaspartic resin is developed to meet these needs. With touch-dry performance in about 5 minutes, reliable protection, and broad formulation flexibility, F220 gives coating manufacturers a practical resin choice for fast-curing, durable systems.

What Is F220?

F220, also known as FEISPARTIC F220 polyaspartic ester resin, is an aliphatic, solvent-free, secondary amine-functional resin. It reacts directly with isocyanates (-NCO) and is used as a fast-curing core raw material in third-generation polyaspartic polyurea systems.
In simple terms, F220 is a resin raw material designed for fast curing and durable protection. When formulated into coatings, it helps achieve faster application, better film formation, and longer-lasting performance.

Key Product Data

Key Advantages of F220

1. Fast Curing: Touch-Dry in About 5 Minutes

F220 contains highly reactive secondary amine groups. When used with HDI trimer, it can reach touch-dry in about 5 minutes at room temperature.
This helps reduce waiting time and improve production or jobsite efficiency. It is especially useful for projects that require fast turnaround, continuous application, or quick return to service.

2. High Solids, Low Viscosity, and Easier Application

F220 combines high solids content with low viscosity, making it easier to formulate and apply.
Its solids content is 97±2%, which supports low-VOC and near-solvent-free coating systems. At the same time, its viscosity is only 60–100 mPa·s at 25°C, giving it good flow, sprayability, and leveling performance.
For formulators and applicators, this means better handling without sacrificing environmental performance.

3. Good Film Appearance and Long-Term Protection

Coatings made with F220 offer a good balance of appearance, toughness, and long-term protection.
F220 helps deliver good leveling, high gloss, and a clean film appearance. As a resin, it appears as a colorless to pale yellow-green transparent liquid.
The cured coating also offers good flexibility and toughness, helping reduce cracking caused by movement or stress in the substrate. It provides strong adhesion to a wide range of materials, including plastics such as ABS, PC, and PVC, as well as metals such as steel and aluminum alloy.
In terms of protection, F220-based coatings can provide resistance to weathering, water, solvents, acids and alkalis, and salt spray. This makes them suitable for outdoor exposure, humid and corrosive environments, and demanding industrial conditions.

4. Stable, Reliable, and Highly Compatible

F220 offers good system stability and broad formulation flexibility. It can be used in different coating and elastomer systems depending on the required performance profile.
It can also be used as the R component in SPUA spray polyurea elastomer systems, where it can serve as both the main resin and a chain extender. This gives formulators more flexibility with one material.

Application Areas

1. Heavy- and Light-Duty Anti-Corrosion Coatings

F220 can be used in protective coatings for steel structures, oil pipelines, chemical equipment, storage tanks, and other corrosion-prone substrates. It helps extend coating life in demanding environments.

2. Waterproofing and Repair Systems

F220 is suitable for concrete waterproofing, leak repair, roof waterproofing, and underground anti-seepage systems where fast curing and long-term durability are important.

3. Roads and Traffic Facilities

F220 can be used in fast-drying road marking coatings. These systems support faster application, earlier traffic opening, and good resistance to wear and weathering.

4. Adhesives

F220 is also suitable for high-weatherability and high-strength adhesive systems, including structural adhesives, composite adhesives, and industrial bonding formulations.

5. SPUA Spray Polyurea Systems

As a core raw material for the R component, F220 can be used in spray polyurea elastomers, protective coatings, wear-resistant flooring, and other high-performance systems.

F220 is designed to perform in complex and demanding environments while helping extend coating service life. It combines fast curing, durable protection, environmental advantages, and broad formulation flexibility.
For coating manufacturers looking for a fast-curing polyaspartic polyurea resin that is easy to formulate and suitable for multiple applications, F220 is a practical choice.
