About This Product

■No boric acid

・Minister of Land, Infrastructure, Transport and Tourism Noncombustible Material Certification Number NM-1050 ・Minister of Land, Infrastructure, Transport and Tourism Semi-noncombustible material certification number QM-0370 The efflorescence-free, noncombustible wood almost eliminates the efflorescence phenomenon.

■No use of boric acid, which causes efflorescence. The chemical is in the neutral range, so it won't rust easily.

Efflorescence-free flame-retardant wood uses a special phosphoric acid-based chemical (no boric acid). As a result of weathering tests, the results showed that excessive moisture absorption was controlled and the efflorescence phenomenon was almost completely eliminated. We also succeeded in suppressing corrosion (rust) of the joint metal by using neutral chemicals. Are you worried about efflorescence and dripping?

■Why efflorescence occurs

General non-combustible wood has excessive hygroscopicity, which causes the chemicals to dissolve and cause drips. Due to aging, the drug hardens and appears as efflorescence. Additionally, since the chemicals used for fireproofing are usually acidic, acidified fireproofing wood will corrode many metal objects such as nails and bolts.
