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第一道密封胶。具有高气密性与优异的抗紫外线能力，与硅酮胶、聚硫胶等构成一个优异的抗湿气系统。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：
中空玻璃生产中第一道密封，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.
