Creating a safe and comfortable space with the power of plaster

Adsorbs ammonia, hydrogen sulfide and methylcaptan, the main causes of unpleasant odors. It is also a countermeasure against bacteria, germs, mold, and household odors such as the smell of cigarettes and pets.

Strong alkaline calcium hydroxide inhibits the growth and proliferation of bacteria and viruses.

[Antibacterial effect]

An antibacterial activity value of 2.0 or higher, as determined by the test method specified in JIS Z 2801, is considered to be effective.

[Measuring method] JIS Z 2801 compliant. – Bacteria (100,000 to 400,000 bacteria) are placed in contact with antimicrobial treated objects, and the increase or decrease in the number of contacted bacteria is measured to confirm the antimicrobial effect compared to non-treated products.　In-house research.

[Antiviral effect]

Adsorbs VOCs such as formaldehyde, a causative agent of sick house syndrome.
It can be effective in spaces with children, elderly people and pets with low resistance.

It is expected to lower the carbon dioxide concentration in the room and reduce its effect on the body.

High moisture absorption and desorption inhibits mold and condensation absorption and desorption properties were compared. shikkui fleece were 105g / ㎡, while normal vinyl cloth absorbed 43g / ㎡. The amount of moisture released was 16 g / ㎡ with vinyl cloth, while it was 77 g / ㎡ for shikkui fleece.

“eterno” has high moisture absorption properties and is less prone to condensation than vinyl cloth.

[Methods] The experimental apparatus was set up in a room temperature of 25°C. A container of water was placed in the apparatus. A container filled with water was placed in the device and warmed by a 40W light bulb, and humidity and condensation conditions were measured after six hours. In-house investigation

“eterno” has high tensile strength. This makes it resistant to tearing when the wall surface is displaced or moved by cracks or distortions in the building.
The tensile strength of shikkui fleece was compared with vinyl cloth.
The tensile strength of vinyl cloth was 46 N / 15 mm in the vertical direction and 31.4 N / 15 mm in the horizontal direction, while the tensile strength of shikkui fleece was 133 N / 15 mm in the vertical direction and 76.4 N / 15 mm in the horizontal direction. It was.

[Methods] Complies with JIS P 8113. The tensile strength of paper and paperboard is measured using a constant-speed extension tester. In-house research

This is a paper-lined wallpaper with a sheet of polyvinyl chloride resin (PVC).
Because the backing is paper, it has low strength and is not able to respond to the movement of the building structure, and is prone to cracks and tears.

Concrete develops cracks (cracks) due to building movement and distortion. When painting directly onto concrete, if cracks appear in the substrate, the finish will crack as well.

Concrete painted wall with cracks in it

The high strength fleece “eterno” does not follow the cracks and keeps a good appearance.

“shikkui fleece” has low elongation in water and is less prone to stretching and shrinking due to moisture. Therefore, unlike vinyl cloth, it is less likely to expand or contract due to moisture and less likely to move or peel off from the wall caused by expansion or contraction.

	Water elongation
vinyl cloth	1%
eterno	＞0.3%

In accordance with the German Industry Norm DIN 53130. Testing of humidified elongation of paper and board using a strain measuring device. In-house research

Plasticizers are added to vinyl cloth to make PVC resin (PVC) more flexible, but UV light exposure releases the plasticizer.
In the process, the flexibility is lost from the PVC.
As a result, the vinyl cloth will harden in 5-6 years and the joints in the cloth will open up.
In addition, degradation and yellowing of PVC without plasticizer will occur. In this respect, the fleece wallpaper without plasticizer is unlikely to deteriorate.

Discarded vinyl cloth

“shikkui fleece” is part of the “eterno” series, FSC Certified, which is rare in Japan.

※ FSC ・・・ FSC certification ensures that products come from responsibly managed forests that provide environmental, social and economic benefits.

“shikkui fleece” can be painted over with a water-based paint. This reduces waste as there is no need to remove the existing wallpaper when renovating.

“eterno”, unlike vinyl cloth, does not use plasticizers. Plasticizers contain endocrine disruptors, which can cause sick building syndrome.
Plasticizer-free fleece wallpaper does not emit VOCs and poses no threat to sick building syndrome.

In Japan, F☆☆☆☆, the highest of the four grades of formaldehyde emissions set by JIS (Japanese Industrial Standard) and JAS (Japanese Agricultural Standard) , has been certified.
