抗冻FG深冷粘结剂

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 glue cellular glass, PIR-polyisocyanurate and PUR-polyurethane under cryogenic temperature. It has excellent flexibility and bonding strength at low temperature.

使用方法/Usage
1、使用时先将粘结剂加热至180℃～200℃，使其熔化。
2、用刮刀、棕刷或自制工具，将熔化的粘结剂抹在泡沫玻璃、聚异氰脲酸酯或聚氨酯粘合面上，趁热压紧粘合。待稍冷固定后刮去多余粘结剂。粘结剂涂抹均匀，粘合缝无空隙。
3、粘合剂随用随熔，不宜长时间加热或温度过高，一般可用烟色判断，青—白—黄，呈黄色时已近火点，需注意。
1、Heat the adhesive between 180℃～200℃ to melt it.
2、Smear the adhesive by using scrapper, brushes or self-made tools to apply it onto the base of cellular glass, PIR-polyisocyanurate and PUR-polyurethane, and press tight when it is hot. When it cures, scrape the redundant adhesive. The adhesive shall be homogenously applied and no clearance shall exist.
3、The adhesive should be used up immediately and not to heat it for long time or under a too high temperature. Usually, you can judge it through the color of smoke, which turns from green to white and then yellow. When it turns yellow, it has approached flash point and special care shall be taken.
