产品说明：

    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-polyisocyanurateand 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.
