LR-1330 Polyether-Based Polyaspartic Resin

LR-1330 is a specialized, solvent-free polyaspartic resin based on polyether technology. Featuring a unique secondary amine structure, it is engineered for high-performance coatings that require a longer induction time and extended pot life compared to standard resins like LR-1420.

For large-scale projects where application consistency is critical, LR-1330 provides technical teams with the "safety window" needed to achieve a flawless, high-gloss finish without the risk of premature gelation.

Technical Advantages: Why Specify LR-1330 Polyaspartic Resin?

In the professional B2B sector, performance is measured by both durability and ease of application. LR-1330 delivers excellence in both:

1. Extended Open Time for Large-Scale Application

One of the most significant challenges in polyaspartic systems is the rapid cure rate. LR-1330 is specifically designed to offer a longer curing time and extended workability. This makes it the ideal choice for large industrial floors or complex steel structures where installers need more time for leveling and overlapping.

2. Exceptional Film Fullness and Gloss

LR-1330 is renowned for its optical clarity and film fullness. It creates a "wet look" finish with high gloss that enhances the aesthetic value of the substrate while providing a robust protective barrier. Whether used as a clear coat or a pigmented topcoat, it ensures a premium surface texture.

3. Low-Temperature Flexibility (-35°C)

Mechanical integrity is maintained across extreme thermal ranges. LR-1330 remains completely crack-free at -35°C, effectively resisting the stresses caused by the expansion and contraction of underlying cement boards or metallic substrates.

4. High-Performance Abrasion and UV Shielding

• UV Resistance: Retains over 95% of performance after 4,000 hours of QUV-A testing, outperforming traditional protective materials.

• Wear Defense: Demonstrates outstanding abrasion resistance with a weight loss of ≤20mg (500r/750g), extending the service life of heavy-traffic environments.

Diverse Application Scenarios

LR-1330’s polyether backbone makes it a versatile primary resin or blending agent:

• Automotive & Premium Wood: Significantly enhances gloss and film build in high-end finishes while accelerating through-dry time for industrial lines.

• Heavy-Duty Corrosion Protection: Serving as a moisture-resistant topcoat for petroleum pipelines, steel structures, and bridges.

• Flooring Systems: Perfect for industrial workshops, residential floors, and basketball courts where high-build, seamless protection is required.

• Wind Energy: Used in the production of gel coats and putties for wind turbine blade protection.

• Specialty Landscaping: Provides a durable, weather-resistant coating for foam-based sculptures and landscapes.

Formulation & Blending Potential

As a highly compatible polyaspartic resin, LR-1330 can be tailored for specific mechanical outcomes:

• Elastic Formulations: When paired with flexible curing agents, it creates elastomers with superior elongation.

• Rigid Topcoats: When blended with HDI trimers or rigid hardeners, it produces a 2H hardness film that resists impact and chemical exposure.
