The aging of infrastructure facilities and buildings progressing nationwide has become a challenge that society as a whole must address. Many social capital and buildings, such as bridges, tunnels, apartment complexes, factory facilities, and piping equipment, developed since the period of rapid economic growth, are reaching their renewal period. The question is how to maintain safety and extend their lifespan within limited budgets and human resources.
Meanwhile, at construction and repair sites, concerns about the supply and rising prices of solvents, commonly known as thinners, used in paints and repair materials, have become an issue. Construction methods that rely on conventional solvent-based materials are being re-evaluated not only from the perspective of material procurement but also from the viewpoint of VOC (Volatile Organic Compound) countermeasures and workplace safety.
In this situation, repair materials utilizing water-based technology are attracting attention as a new option for sustainable maintenance and management.
However, water-based paints have existed before. While excellent in environmental performance and safety, solvent-based materials were often chosen for harsh environments such as public infrastructure and factory facilities. This is because conventional water-based materials were seen to have challenges in terms of adhesion, durability, rust prevention, waterproofing, and chemical resistance for high-performance repair and protection applications.
In contrast, the "WH Series" developed by WHiTE Co., Ltd. (Kagoshima City, Kagoshima Prefecture) is not just a water-based paint, but a water-based repair material that emphasizes the functions required for repair and protection applications. It possesses the necessary performance for each application, such as rust prevention, waterproofing, chemical resistance, non-flammability, penetrating adhesion, and flexibility, and is looking to expand into areas where conventional water-based paints had difficulty.
This series is a group of materials designed to be independent of solvent-based materials, aiming simultaneously for reduced environmental impact, safety during construction, and extended lifespan of existing structures.
Furthermore, the materials used in this series have a track record of being registered with NETIS as a technology under a different name and have been utilized in public works projects. Against this background, they are attracting attention as repair materials that address on-site challenges in the maintenance and management of public infrastructure.
One of the flagship products, "WH-110," combines rust prevention, waterproofing, and chemical resistance, and is suitable for protection applications in harsh environments such as steel parts, equipment, factory facilities, and infrastructure-related components.
"WH Fine Cera Water-based" is a water-based material with non-flammable performance and long-term durability equivalent to approximately 30 years. Furthermore, performance evaluations regarding static charge suppression are currently underway, confirming its potential for use in factory and equipment environments where static electricity countermeasures are required.
Penetrates cracks and to the bottom (WH-100)
In addition, "WH-100" contributes to repairs that utilize existing substrates due to its high permeability and adhesion. Its design, which emphasizes penetration and adhesion to deteriorated substrates, helps extend the life of structures without relying on removal or large-scale renewal.
Moreover, it can be used for preventing spalling of tunnel inner walls, and tests are underway for its use in slab waterproofing applications for bridges. It is expected to be deployed as a material that enhances safety while utilizing existing structures in the maintenance and management of public infrastructure such as roads, bridges, and tunnels.
Furthermore, "WH-13" is a material developed as a flexible anionic resin mortar. Utilizing the characteristics of anionic resins, it has followability to moving substrates and cracked areas that were difficult to handle with conventional rigid mortars, and is being developed as a highly unique repair material.
These "WH Series" products have already been adopted in major corporate projects and public works, confirming their practical utility on site.
Until now, countermeasures for aging have mainly focused on large-scale construction projects based on removal and renewal. However, against the backdrop of increasing waste, prolonged construction periods, cost burdens, and labor shortages, there is growing interest in "life-extending repairs" that restore and improve the performance of existing structures.
Repair using water-based materials is one realistic method that not only addresses thinner supply concerns but also simultaneously promotes VOC countermeasures, improvement of the working environment, reduction of environmental impact, and extension of infrastructure lifespan.
The conventional perception that "water-based = good for the environment, but inferior to solvent-based in terms of performance" is beginning to be re-evaluated in the field of repair materials. WHiTE Co., Ltd. will continue to contribute to solving challenges in the maintenance and management of public infrastructure and buildings through water-based technology.
