Unilin Technologies and i4f have announced a strategic non-assert agreement concerning water-repellent coating patents used in laminate and wood flooring. The collaboration marks a significant development in flooring technology licensing. It enables broader access to advanced coating systems across the global market.
Both companies operate as independent technology licensors. Each offers distinct solutions designed to improve moisture resistance in wood-based flooring products. Unilin Technologies markets its solution under the Unicoat brand. Meanwhile, i4f provides its innovation through the AquaProtect platform.
The agreement allows i4f to extend additional legal protection to its licensees. This protection is linked to Unilin’s established patent portfolio. As a result, manufacturers can now access multiple coating technologies without legal uncertainty. This move simplifies adoption across the industry. It also encourages innovation and competition.
Unicoat has been developed as a patented edge-coating technology. It is applied during the production phase. The coating targets specific areas along the panel edges. Once installed, it creates a sealed barrier between flooring boards. This barrier is highly effective. It prevents water from penetrating the joints.
Moisture intrusion is a major issue in wood-based flooring. It often leads to swelling and structural damage. In many cases, mould formation follows prolonged exposure. Unicoat addresses these concerns directly. It reduces the risk of long-term deterioration. The coating keeps liquids on the surface.
The system works without altering the coreboard material. This is important for manufacturers. It ensures cost efficiency while maintaining product integrity. High-density fibreboard (HDF) cores remain unaffected. The coating simply enhances their performance.
Unicoat serves three primary functions. First, it prevents leakages between connected panels. Water is blocked from seeping into joints. This avoids hidden moisture accumulation beneath the floor.
Second, it protects against long-term water damage. A protective layer is formed over the coreboard. Moisture absorption is significantly reduced. Swelling is minimised. Surface wear is also controlled.
Third, it prevents discolouration. Liquids remain as droplets on the surface. They do not penetrate the decorative layer. This preserves the visual quality of the flooring.
Short-term exposure to water is common in residential and commercial settings. Cleaning processes also introduce moisture regularly. Therefore, reliable protection is essential. Unicoat ensures durability under such conditions. It supports extended product life cycles.
The coating performs best when used alongside Unilin locking systems. These systems feature pretension technology. This enhances joint tightness. It further improves water resistance. Together, they create a highly resilient flooring solution.
Performance validation is a key aspect of the technology. At Unilin Technologies, waterproof capabilities are rigorously tested. Industry-standard procedures are followed. Additional internal tests are also conducted.
One widely recognised method is the NALFA test. In this process, a water-filled cylinder is placed on a floor joint. Swelling is measured at different intervals. These include initial, 24-hour, and 48-hour stages. The test focuses on long-term deformation.
Unicoat exceeds standard requirements. It has demonstrated strong results even in extended durations. Tests have been conducted up to 72 and 100 hours. Performance remains consistent.
Another method evaluates watertightness directly. A cylinder filled with coloured water is used. Detection tools identify any leakage through the joint. This may involve absorbent paper or imaging systems.
In such tests, leakage has been effectively prevented. Results have shown resistance for up to 100 hours or more. This highlights the reliability of the coating. It ensures that moisture remains on the surface.
Cleaning efficiency is also improved. Dirt and bacteria can be removed easily. A damp cloth is sufficient in most cases. The surface remains intact. No damage is caused during cleaning.
The agreement between Unilin Technologies and i4f represents a practical step forward. It promotes collaboration without restricting innovation. Manufacturers benefit from increased flexibility. They gain access to multiple proven technologies.
The flooring sector continues to evolve. Demand for waterproof solutions is rising. Consumers expect durability and ease of maintenance. Technologies like Unicoat and AquaProtect respond to these needs.
With this non-assert agreement in place, industry adoption is expected to accelerate. New standards may emerge. Enhanced product performance will likely follow.
