TOPBEST-702中空玻璃用热熔丁基胶

一、产品概述：
TOP BEST-702热熔丁基胶是一款具有塑性的中空玻璃用道密封胶。具有高气密性与的抗紫外线能力，与硅酮胶、聚硫胶等构成一个的抗湿气系统。在-40℃~130℃范围内连续使用20小时不碳化、不失粘、不分解，密度低，亮度高，挤出成型性佳。

Description:
TOP BEST-702 is the first insulating glass sealant with permanent plastic. Based on its high airtightness and excellent UV resistance,it can be a superior anti-moisture system together with Silicone sealant or polysulfide sealant. In the -40 ℃~130 ℃ within 20 hours of continuous use of non-powder, non-hardening, without losing stick, do not decompose.Low density, high brightness, excellent extrusion.

二、适用范围：
中空玻璃生产中道密封，与聚硫胶、硅酮胶配套使用，以完成双道密封。中空玻璃生产线中使用热熔胶挤出机涂敷，可通过调整温度和压力控制好出胶量，挤出温度范围为120℃-140℃，施工时环境温度要求不低于8℃。

Application Area:
As a first insulating glass sealant in insulating glass production,to complete the double sealing with Silicone sealant, polysulfide sealant.Keep the applying area clean and dry,use the special hot-melt extrusion pump.Extrusion temperature at 120℃-140℃, environmental temperature >8℃.Control of the glue by adjusting the rubber pump with the difference of the temperature.
