Water Supply Facility Polyurea Corrosion Protection - AY Corrosion Protection JW-PU Method
AY Anti-Corrosion JW-PU Method
"Yamade's corrosion protection" protects facilities safely from concrete corrosion in water supply systems.
To protect water supply facilities from concrete corrosion, it is necessary to apply an anti-corrosion lining material that has adhesion and protective effects on concrete, and does not adversely affect water quality for drinking water use. The AY Anti-Corrosion JW-PU method is a polyurea anti-corrosion construction method developed for water supply facilities. It possesses excellent durability, workability, and safety, and protects concrete structures such as water purification plants and distribution reservoirs over the long term. Main applications: water supply facilities, irrigation channels, water storage tanks, receiving tanks, distribution reservoirs, water purification ponds, fish farming facilities, marine structures, etc. 1. Compliance with water quality standards The entire method, including the anti-corrosion lining material and substrate adjustment materials, is a highly safe anti-corrosion method that complies with water quality tests and physical property tests. 2. Safety It is solvent-free and VOC-free, resulting in minimal odor generation. This significantly reduces the burden on workers and surrounding residents. 3. Workability Due to its ultra-fast curing type, the construction period from substrate adjustment to anti-corrosion coating can be significantly shortened compared to other methods (vinyl ester resin / epoxy resin non-woven / epoxy resin with woven fabric). 4. Short construction period Because it is mechanically applied using a dedicated reactor and spray gun, it minimizes variations in craftsmen's skill levels, achieving a stable quality of the coating film.

Company information
Akiyamade Co., Ltd. is engaged in the development, manufacturing, and sales of PVC resin-based sheet waterproofing materials. We are well-known for our "mechanical fastening method," which fixes PVC sheet waterproofing to roofs and floors using induction heating devices. In addition to rooftop waterproofing, we also offer "integrated waterproof solar foundations," which allow for the installation of solar panels on flat roofs without concerns about waterproofing. Our products are useful for the increasing demand for renewable energy, particularly in the installation of solar equipment on rooftops.
