PLUSNATE C-500-xx Series:

Polyurethane-Based, Solvent-Free Binder System

The PLUSNATE C-500-xx Series is a polyurethane-based, solvent-free, aromatic single-component bonding system formulated to react with air moisture or externally added water droplets. Designed for industrial applications, this polyurethane binder delivers strong adhesion for EPDM rubber and SBR rubber, making it suitable for professional flooring manufacturers, contractors, and B2B surface system providers who require consistent, durable, and long-lasting performance.

High-Strength Bonding for EPDM and SBR Rubber

The primary purpose of the PLUSNATE C-500-xx Series is to ensure reliable bonding in systems using EPDM rubber and SBR rubber granules. Its polyurethane-based structure creates a high-strength adhesive layer that maintains integrity under heavy foot traffic and long-term outdoor exposure. The flexible structure formed after curing makes the product resistant to breakage and external pressures, ensuring that surfaces remain durable for many years. This performance is especially critical for parks, sidewalks, pedestrian paths, walkways, playgrounds, and other outdoor areas where EPDM and SBR flooring systems are commonly used.

Moisture-Reactive Polyurethane Technology

As an aromatic, single-component polyurethane binder, the PLUSNATE C-500-xx Series activates upon contact with air humidity or lightly applied water droplets. This moisture-curing mechanism gives the product predictable behavior during installation and allows applicators to work efficiently in various conditions. The formulation supports stable and uninterrupted curing, which is essential for large-scale B2B projects requiring high reliability and consistent adhesion across wide application surfaces.

Durable and Flexible Structure After Curing

Once cured, the polyurethane binder forms a flexible structure that resists cracking, deformation, and external mechanical stress. This flexibility is one of the main advantages of the polyurethane system and is a key factor behind the long-term durability of surfaces bonded with the PLUSNATE C-500-xx Series. Projects such as playground flooring, walking tracks, pedestrian routes, and open-air recreational surfaces benefit significantly from this type of binder, as it helps maintain both elasticity and structural integrity over time.

Importance of Clean and Dust-Free Granules

For maximum bonding performance, the granules used in the application must be thoroughly cleaned from dust and debris. This is one of the most critical steps in achieving optimal adhesion. Dust particles prevent the polyurethane binder from fully attaching to the EPDM or SBR granules, reducing the overall bonding strength. By ensuring that the granules are clean, the polyurethane binder can create a stronger and more uniform bond. This step directly affects the long-term durability and performance of the finished surface, and therefore requires careful attention by all professional applicators and contractors.

Application Considerations for Optimal Performance

During the application process, ensuring even distribution of the polyurethane binder across EPDM or SBR granules is essential. Proper mixing allows the aromatic polyurethane binder to coat each granule effectively, creating a cohesive and durable structure. A uniform distribution results in a more stable surface that performs consistently under outdoor conditions. The flexibility of the cured binder helps the system adapt to movement and environmental factors, reducing the risk of cracking and improving long-term reliability.

Long-Term Performance for Outdoor Surfaces

The PLUSNATE C-500-xx Series provides long-lasting durability required for outdoor flooring systems. Its polyurethane-based formulation delivers stable adhesion, and its flexible cured structure helps maintain performance in surfaces exposed to daily wear. Because this binder is solvent-free, it supports a cleaner and more controlled installation process, an important factor for professional B2B applications where product safety, consistency, and reliability are critical.
