F330: A Polyaspartic Resin That Balances Performance, Workability, and Cost

What Is F330?

F330 is a solvent-free polyaspartic ester resin containing secondary amine groups that react with -NCO groups. It is designed for high-solids and solvent-free systems and can be used in elastic coatings, waterproofing materials, sealants, and adhesives.

With a good balance of workability, flexibility, and low-VOC performance, F330 gives formulators a practical option for polyurea-based systems. It is well suited to projects that need reliable performance while keeping material costs under control.

Key Advantages

Ultra-High Solids for Better Durability and Lower VOC

F330 has a solids content of 97±2%, which means it contains very little volatile material or unnecessary solvent. This helps form a denser cured film and supports better long-term durability. After curing, coatings made with F330 are less likely to chalk, crack, or lose performance over time.

For end users, this can mean longer maintenance intervals and lower repair costs. With low VOC and very low odor, F330 also supports cleaner production, safer application, and compliance with stricter environmental requirements.

Very Low Viscosity for Easier Application

At 25°C, F330 has a viscosity of only 250–600 mPa·s, giving it excellent flow and workability.

• Solvent-free formulations can be brushed, troweled, or poured smoothly without the need for extra thinners. The material can also flow into difficult areas such as tile gaps, fine joints, corners, and complex edges.
• For small repairs, manual application, or on-site maintenance work, F330 makes the process easier and more forgiving.
• It can help reduce common problems such as missed edges, poor filling, and uneven coverage.

High Elastic Recovery and Flexibility

When used with elastic isocyanate curing agents, F330 can be formulated into elastic materials with elongation of up to 400%.

• The cured coating can maintain flexibility and recovery even under long-term stress, temperature changes, or substrate movement.
• Coatings based on F330 are less likely to become brittle, crack, or delaminate. They are well suited to areas affected by thermal expansion and contraction, vibration, settlement, or impact.
• That flexibility is especially useful in waterproofing, sealing, and protective coatings, where the material needs to move with the substrate over time.

Balanced Reactivity for Easier Manual Work

F330 is designed with moderate reactivity, giving applicators more working time when using hand-applied polyaspartic coatings. This helps reduce issues such as rapid thickening, sagging, pinholes, and uneven film formation. Even in non-automated, small-batch, or on-site repair applications, F330 can help produce a smooth and attractive coating surface.

Good Film Appearance with Multi-Use Value

Coatings made with F330 offer good leveling, gloss, and basic weather resistance. They can provide both decorative and protective functions in a single system. In many applications, F330 can help reduce the number of coating layers, simplify formulation work, and lower overall application costs. It can be used across a wide range of systems, including elastic flooring, waterproofing, sealing, and bonding applications.

Key Performance Data

Application Areas

High-Elongation Waterproof Coatings

F330 is suitable for waterproofing applications such as roofs, bathrooms, kitchens, basements, and underground structures. Its high elasticity allows the coating to adapt to movement in the base layer.

It can also be used for waterproofing repairs without removing existing tiles, where a flexible and well-sealed coating is needed. Because it is solvent-free and low in VOC, F330 is also suitable for long-term waterproof sealing in damp environments.

Solvent-Free Sealing and Bonding

F330 can be used in tank sealing, structural adhesives, composite adhesives, and other sealing or bonding systems. It combines high strength with high elasticity, helping the material maintain a tight seal and a strong bond under mechanical stress and exposure to aggressive chemicals or other harsh conditions. This makes it well suited to demanding industrial environments where durability and flexibility are both essential.

Elastic Protective Coatings

F330 is also suitable for substrates exposed to deformation, vibration, or impact, such as sports equipment, running tracks, and elastic flooring. Coatings made with F330 provide good rebound performance and impact resistance while maintaining flexibility and protection.

Compared with traditional flexible materials, F330-based systems can help reduce cracking, peeling, hollowing, and other common failure problems. The result is a highly elastic, crack-resistant, and long-lasting protective coating.

F330 is a practical fit for formulators who need flexibility, low VOC, and easy handling in the same resin. Its high solids content reduces unnecessary solvent, while its low viscosity makes solvent-free application easier. Paired with suitable isocyanate curing agents, it can deliver the elasticity required for waterproofing, sealing, bonding, and protective coating systems.

For industrial waterproofing, building renovation, elastic flooring, sealants, adhesives, and home repair applications, F330 offers a reliable balance of durability, flexibility, and cost efficiency.
