Product Overview

ZDM Floor Joint Sealant is a functional sealing material developed specifically for concrete floor joint applications. Formulated with high-molecular polymer as the base material and enhanced with selected additives and fillers, it provides reliable joint filling and long-term protection for industrial flooring systems.The product effectively seals construction and movement joints, preventing the intrusion of water, dust, and debris. Its excellent elasticity allows it to absorb stress caused by temperature variations, minor settlement, and dynamic loads, helping to protect the floor structure and maintain surface integrity.

The Floor Joint Sealant is a specialized sealing material designed for filling joints and gaps in concrete flooring systems. It offers excellent adhesion, wear resistance, weather resistance, and environmental performance, making it an essential component in modern flooring construction.

This sealant is primarily used to fill and protect floor joints, creating a smooth, clean, and visually consistent surface. At the same time, it helps enhance the durability of the floor by preventing dust, moisture, and debris from entering the joints, thereby extending the overall service life of the flooring system.

With the continuous development of flooring technologies and increasing demands for higher-quality finishes, floor joint sealants are constantly evolving. Modern formulations focus on:

• Improved durability and flexibility
• Enhanced environmental performance
• Longer service life
• Better compatibility with different flooring systems

As a critical element in flooring projects, the performance of joint sealants directly affects the appearance, functionality, and longevity of the floor. Therefore, selecting the right sealant and applying it properly is essential to ensure optimal results in both industrial and commercial applications.

The Floor Joint Sealant demonstrates excellent overall performance across key technical parameters. It features a smooth and uniform paste consistency with no bubbles or gel formation, ensuring stable application quality.

The product exhibits outstanding flowability, with a sagging value of 0 mm, significantly better than the standard requirement of ≤3 mm, allowing for precise application without deformation.

With a tack-free time of approximately 2.5 hours, it ensures efficient curing while maintaining sufficient working time for installation. The sealant also provides excellent extrudability, reaching 421 mL/min, which greatly improves application efficiency compared to the standard requirement of ≥150 mL/min.

In terms of elasticity, the material maintains stable performance under different temperature conditions, with elastic recovery values of 0.27 at 23°C and 0.38 at -20°C, meeting the required standards for flexibility and durability.

Additionally, the sealant shows no damage under tensile modulus testing, confirming its strong structural integrity and long-term reliability.

Overall, these performance characteristics make the product highly suitable for demanding flooring applications, ensuring durability, flexibility, and consistent sealing performance.
