LR-2000 Polyaspastic Resin

LR-2000 is a solvent-free, aliphatic polyaspartic resin engineered with a bis-secondary amine structure. It is specifically developed for coating systems where clarity, aesthetic fullness, and environmental resistance are paramount.

For technical engineers and procurement specialists, LR-2000 offers a high-performance alternative to traditional systems, providing the ability to cure at room temperature while delivering an exceptional balance of mechanical toughness and optical transparency.

Technical Performance

Unlike multi-purpose resins, LR-2000 is optimized for "high-build transparency," ensuring that waterproof repair layers do not compromise the aesthetic integrity of the substrate.

1. Superior Film Quality and Fullness

LR-2000 is characterized by its ability to deliver an exceptional film build and "fullness." This results in a high-gloss, mirror-like finish that is highly valued in the automotive refinish and architectural coating sectors.

2. Verified 4,000-Hour Weathering Resistance

Durability is confirmed via the QUV-A testing protocol. After 4,000 hours of continuous UV exposure, coatings based on LR-2000 retain over 95% of their initial performance. Its inherent resistance to yellowing, chalking, and degradation ensures long-term protection for outdoor assets.

3. Thermal Stability and Crack Resistance (-35°C)

Mechanical flexibility is a core requirement for exterior building components. This polyaspartic resin remains crack-free at temperatures as low as -35°C, effectively managing the stresses of thermal expansion and contraction in windowsills and balconies across diverse climates.

4. Low-Viscosity Formulation for 100% Solids

With a viscosity of 200-900 mPa·s (@ 25°C), LR-2000 allows for the formulation of low-VOC or 100% solid-content coatings. It ensures excellent substrate wetting and leveling, making it suitable for brush, roller, or trowel applications without the need for additional solvents.

Technical Specifications

Every batch of LR-2000 is manufactured to meet these stringent chemical parameters to ensure consistency in your manufacturing process:

Applications

The molecular design of LR-2000 polyaspartic resin makes it an ideal backbone for coatings in sectors where structural durability must meet aesthetic precision:

• Transparent Waterproof Repairs: Specifically recommended for exterior walls, windowsills, and balconies. Its high clarity and UV stability allow for invisible patching that prevents water ingress without altering the building's appearance.

• Elastic Protective Coatings: Optimized for formulating high-elongation, high-build systems for swimming pools, roofs, and storage tanks. It creates a seamless, flexible barrier that moves with the substrate.

• Resilient Industrial Flooring: Used to produce solvent-free, high-load coatings for industrial workshops, residential garages, and parking decks. It provides a tough surface that resists both mechanical impact and chemical spills.

• High-Performance Sports Surfaces: Ideal for outdoor basketball courts and multi-purpose tracks where color retention and impact absorption are required.

Technical Formulation Flexibility

For formulators and chemists, LR-2000 acts as a versatile reactive matrix. By adjusting the B-component (Isocyanate), the final mechanical properties can be precisely tailored:

• Rigid Finishes: When cross-linked with rigid hardeners (e.g., HDI trimers or dimers), LR-2000 produces films with a pencil hardness of up to 2H, offering superior scratch resistance.

• Elastomeric Systems: When paired with flexible curing agents, it yields high-elongation elastomeric membranes capable of bridging micro-cracks in concrete or masonry.

• Application Versatility: The resin is fully compatible with professional application methods including high-pressure impingement spray, roller, brush, and trowel.

Packaging, Storage, and Safety

• Packaging: Standardized 200 KG UN-certified drums. 1-ton IBC tanks are also available for bulk industrial requirements.

• Shelf Life: 12 months when stored in original, unopened containers at temperatures ≤30°C.

• Storage Conditions: Store in a cool, dry, well-ventilated area away from heat sources and open flames.

• Notice: Please review the LR-2000 Material Safety Data Sheet (MSDS) for comprehensive handling, environmental, and health information before use.
