LR-3002 Polyaspastic Resin

LR-3002 is a specialized, solvent-free polyaspartic resin engineered with a unique bis-secondary amino and bicycloaliphatic structure. This molecular design provides enhanced structural stability and high reactivity with -NCO functional groups.

Unlike conventional resins, LR-3002 is optimized to solve the industry-wide challenge of balancing a manageable long pot life with a fast hard-drying cycle. It is a primary choice for technical formulators looking to develop high-solid, environmentally friendly coatings that must perform under extreme environmental stress.

Technical Specifications

As a professional manufacturer, Ruqinba Group ensures that every batch of polyaspartic resin is tested against international standards to provide consistent quality for your production line.

Physical and Chemical Properties

Core Technical Advantages for Formulators

Procurement and R&D teams select LR-3002 for its specific mechanical and chemical benefits:

1. Unique Bicycloaliphatic Stability

The bicycloaliphatic structure imparts superior rigidity and chemical resistance to the cured film. This makes it particularly effective in preventing peeling and maintaining high adhesion strength on diverse substrates, including steel and concrete.

2. Optimized Application Window

LR-3002 is formulated to offer an extended activation period (pot life), allowing for easier manual application (brushing, rolling, or troweling) while still achieving a rapid through-dry. This reduces waste and increases the reliability of the application process in variable field conditions.

3. Extreme Temperature Resilience (-35°C)

Mechanical flexibility is a critical factor for outdoor durability. Coatings based on this polyaspartic resin remain crack-free at temperatures as low as -35°C, ensuring integrity during extreme thermal expansion and contraction cycles of the underlying substrate.

4. 4,000 Hours QUVA Weathering

Verified by rigorous aging tests, LR-3002 maintains over 95% of its performance after 4,000 hours of QUVA exposure. Its resistance to UV-induced degradation, yellowing, and chalking makes it the gold standard for long-term outdoor protection.

Applications

Based on its unique bicycloaliphatic structure and high reactivity, LR-3002 polyaspartic resin is recommended for high-performance formulations in the following sectors:

• High-End Industrial Finishes: Ideal for automotive refinish and premium wood coatings. It significantly enhances film build, surface hardness, and reduces through-dry time in automated production lines.

• Infrastructure Waterproofing: Used as a durable topcoat for swimming pools, petroleum pipelines, and steel bridge structures requiring extreme moisture and corrosion resistance.

• Architectural Flooring Systems: A premier choice for residential garage floors, sports courts, and commercial workshops. It provides a high-gloss, high-build finish that withstands heavy mechanical loads.

• Wind Energy Protection: Applied in gel coats, fillers, and topcoats for wind turbine blades to ensure long-term UV stability and erosion resistance.

• Advanced Tile Joint Sealants: Specifically utilized for manufacturing non-yellowing, solvent-free tile grout, providing excellent aesthetic consistency and waterproof sealing.
