Pyongyang, August 3 (KCNA) — The Technology Institute of the Textile Machine Industrial Management Bureau under the Ministry of Light Industry of the DPRK has developed emulsoid waterproof liquid branded with “Unhasom” by applying latest technology.
It made the liquid with paraffin as main raw material by converting paraffin into super-particles and realizing the safety of its character so as to be proof against any climatic changes.
It is easy to apply it in construction and its waterproof ability is higher than the existing waterproof method of increasing the density of particles per unit and the asphalt watertight method.
The water penetrates 0.1 mm deep under the pressure of 0.8 MPa.
Construction agencies in Pyongyang, Sariwon City and Unryul and Jonchon Counties and other cities and counties across the country are extensively applying it to waterproof projects of toilets, lavatories, underground structures and roofs of buildings.
