FG深冷粘结剂系一种以石油沥青为基料，加入有机溶剂、高分子树脂及增塑剂等辅料，经加温反应而成。具有粘结力强、抗冻性好、能在深冷部位对泡沫玻璃、聚异氰脲酸酯及聚氨酯等保冷材料粘结成型，有较好的柔韧性和低温粘结力。

FG cryogenic adhesive is a developed by High-temperature reaction with asphalt, organic solvent, polymer resin and plasticizer. It has strong bonding strength, excellent freezing resistance, and esay to gluecellular glass, PIR-polyisocyanurateand PUR-polyurethane under cryogenic temperature. It has excellent flexibility and bonding strength at low temperature.
