- ItemDevelopment of organic-inorganic coatings for strength-preserving of glass bottles(Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 2001) Mennig, Martin; Gier, Andreas; Anschütz, Dieter; Schmidt, HelmutAn amino-epoxy-silane based coating system (GAMAL) for glass surfaces was developed, which can efficiently protect bottles from the damages of a bottling plant. Testing bottles with a ramp pressure tester show an identical value of about (40 ± 4) bar for conventionally hot- and cold-end coated bottles and bottles coated with the developed organic-inorganic composite (GAMAL) system. After already 2 min of wet line-simulation testing, all species of a conventionally coated probe fall short of the critical limit of 16 bar, whereas bottles coated with GAMAL (thickness about 7 µm) show a value of (21 ± 3) bar. Coating is possible by dip and spray applicadon on cold or hot (80 °C) substrates, the coating is cured at 120 °C for 5 to 10 min. Additional functions such as colour or UV protection can be added easily, without reduction of the protection potential. The low content of carbon (about 0.5 g per 1 l soft drink bottle) should not disturb the recycling process of such coated bottles.
