Attention. Time between drying of glue and tightening not to dolzhnoprevyshat open time - for this glue – 60 minutes. In 2 – 3 hours of a prochnostkleevy seam reaches 70% of maximum. From this point to mozhnoekspluatirovat connection. Further increase of durability happens slowly, in techenii30 – 40 hours.
