LR-1000 Polyaspastic Resin

LR-1000 is a solvent-free, low-viscosity polyaspartic resin engineered with a poly-secondary amine structure. As a highly reactive secondary amine functional resin, it is designed to cross-link with aliphatic isocyanates at room temperature. The resulting polymer network provides a unique synergy of mechanical toughness, high elongation, and optical clarity.

For coating formulators and technical directors, LR-1000 offers a reliable foundation for developing high-solid-content (100% solids) systems. It is particularly effective for applications where the substrate is subject to thermal stress or requires a high-gloss, non-yellowing protective finish.

Technical Features & Performance Benefits

Technical personnel select LR-1000 based on its ability to meet rigorous industrial standards while maintaining application efficiency:

1. Superior Low-Temperature Flexibility

LR-1000 is formulated to maintain its elastic properties across extreme temperature gradients. Applied coatings remain completely crack-free at -35°C, ensuring long-term structural integrity on exterior walls, roofs, and windowsills exposed to harsh winters.

2. High Fullness and Optical Clarity

This polyaspartic resin endows finished coatings with exceptional "fullness" and self-leveling properties. It is an ideal matrix for high-gloss clear coats (varnishes), providing a deep, mirror-like finish that enhances the substrate's aesthetic without the risk of solvent entrapment.

3. Optimized Reactivity for 1:0.5 Systems

Unlike standard 1:1 systems, LR-1001 is chemically tailored for 1:0.5 high-solid-content waterproof clear varnishes. This specific stoichiometry allows formulators to achieve high film build and rapid curing, making it the industry standard for tile-preserving waterproofing in residential and commercial settings.

4. Eco-Friendly and Ultra-Low VOC

With a 100% solids content and low viscosity (100-1000 mPa·s), LR-1000 enables the production of environmentally friendly coatings with minimal environmental impact. It meets the most stringent global VOC regulations, making it safe for indoor applications in kitchens, bathrooms, and public facilities.

Targeted Applications & Engineering Fit

The low viscosity and high molecular elongation of LR-1000 make it highly adaptable. Technical teams typically specify this resin for the following applications:

1. Demolition-Free Waterproofing Repairs

LR-1000 is uniquely suited for formulating 1:0.5 high-solid clear varnishes. It allows contractors to apply a seamless waterproof barrier directly over existing tiles in kitchens, bathrooms, and rooftops, eliminating the heavy cost and noise of demolition.

2. High-Elongation Elastic Topcoats

By adjusting the cross-linking profile with compatible elastic curing agents, it forms elastomeric membranes. These are used as heavy-duty protective topcoats for outdoor swimming pools, exposed roofs, and dynamic walls.

3. Resilient Industrial & Sports Flooring

Ideal for the R-component in high-performance flooring systems. It produces solvent-free coatings for industrial workshops, residential floors, high-traffic parking garage decks, and basketball courts.

4. Heavy Infrastructure Protection

LR-1000 delivers the required durability for extreme infrastructure environments. It provides the base formulation for waterproofing repair materials on hydropower dams, large water parks, and critical building structures.
