Высока адгези к металлу к стеклу позвол ет по-, лучать на. их основе водостойкие покрыти , имеющие твердость 0,7-0,9 и эластичность . 1-5 мм.but it does not correspond to 143-320%. High adhesion to metal allows glass to shine. They are based on waterproof coatings with a hardness of 0.7-0.9 and elasticity. 1-5 mm.
