LR-1100 Polyaspastic Resin

LR-1100 is a solvent-free polyaspartic resin engineered with a specialized bis-secondary amino and bicycloaliphatic structure. As a highly reactive component with -NCO functional groups, LR-1100 is designed to facilitate the formulation of 100% solid-content, low-VOC coatings that require a balance of long workable pot life and rapid post-application hardening.

For technical directors and procurement managers, LR-1100 is the preferred resin base when the project demands superior optical clarity (Color ≤5) and exceptional mechanical resistance in fluctuating environmental conditions.

Technical Performance

Technical personnel select LR-1100 based on its predictable curing kinetics and robust film properties.

1. Optimized Rheology and Curing

LR-1100 allows for high-build coatings with excellent leveling and gloss. Despite its fast hard-drying capability, it provides a stable activation period, making it suitable for high-pressure impingement spraying as well as manual application (brushing/rolling).

2. Cold Resistance and Structural Stability

Mechanical integrity is maintained across extreme temperature gradients. The resulting film remains completely crack-free at temperatures as low as -35°C, effectively absorbing the stresses generated by the thermal expansion and contraction of underlying substrates like steel or concrete.

3. Verified Weatherability (4,000h QUV)

Data-driven durability is the hallmark of this polyaspartic resin. Under 4,000 hours of continuous QUV accelerated weathering, LR-1100 maintains over 95% of its performance parameters, offering long-term resistance to chalking, yellowing, and degradation.

4. High-Performance Abrasion Resistance

LR-1100 achieves high surface toughness, evidenced by a Taber abrasion loss of ≤ 20 mg (500 cycles/750g load, ASTM D4060), making it ideal for high-traffic environments.

Typical Product Specifications

Every batch of LR-1100 is synthesized to meet standardized industrial benchmarks to ensure consistency in large-scale production:

Applications

The molecular stability of LR-1100 polyaspartic resin allows it to serve as a versatile foundation for both high-end decorative finishes and heavy-duty industrial protection:

• Automotive Refinish & OEM: Engineered to significantly enhance film build, gloss, and surface hardness. Its fast-drying kinetics accelerate production cycles in automotive painting and premium wood finishing.

• Infrastructure Waterproofing: A reliable topcoat for swimming pools, bridges, and petroleum pipelines. It provides a moisture-insensitive barrier that resists osmotic blistering and corrosive ions.

• Industrial & Sports Flooring: Ideal for high-build, solvent-free coatings on garage decks, basketball courts, and foam sculpture protection. It offers a balance of aesthetic fullness and mechanical impact resistance.

• Wind Power Sector: Specifically utilized in gel coats, fillers, and topcoats for wind energy blade protection, ensuring the structure remains durable under high UV exposure and fluctuating wind loads.

• Tile Joint Sealants: LR-1100 is a premier choice for manufacturing non-yellowing, solvent-free tile grout, providing a glass-like finish that is easy to clean and highly resistant to domestic chemicals.

Packaging, Storage, and Safety Standards

• Standard Packaging: 200 KG UN-certified steel drums (also available in IBC tanks for bulk requirements).

• Shelf Life: 12 months from the date of manufacture in original, unopened containers.

• Storage Environment: Maintain at temperatures ≤30°C in a cool, dry, well-ventilated area away from heat sources and sparks.

• Regulatory Compliance: Please refer to the LR-1100 MSDS for detailed safety information regarding chemical handling and environmental protection.
