      基于改性PU聚合物的高质量单组份中性密封粘合剂,具有强粘性。用于建筑物、广场、公路作为嵌缝密封材料,以及汽车制造、玻璃安装、电子灌装、潜艇和火箭等的密封。

性能
-物理性能优越
-兼备粘性与硬度
-起步粘性强,固化后具有高剪切强度
-环保-不含isocyanates(异氰酸盐)、溶剂、卤素及酸性成分
-弹性橡胶-有20%的移动性
-不含气泡的配方(高温及潮湿应用)
-容易加工
-颜色稳定,抗UV辐射能力强
应用
-建筑工业的密封及粘结应用
-有伸缩需求的结构粘结
应用指导
粘结物表面:
粘结材料:包括所有普通的建筑材料,如玻璃、经预处理过的木材、PVC、金属、石材等。
粘结层表面:必须清洁,不含灰尘和油脂;
底涂:多孔表面必须涂底漆,无孔光滑的表面可以使用表面活性剂。

建议在使用之前进行兼容性测试。



应用:
方法: 手动或气动胶枪
应用温度: +5°C 至 +35°C
清洗: 使用后在胶固化前立即用清洗剂清洗 
修饰加工 :在表皮形成前用肥皂水修饰,并用修补
注意事项
   可以施以涂料,然而鉴于涂料和清漆种类繁多,我们建议在使用前做兼容性测试。醇酸树脂类涂料可能需要更长时间干燥;
-由于粘结层材料的多样化,建议在应用前做兼容性测试;
-由于在塑料生产过程中经常会释放化学试剂,添加加工助剂及其他保护剂(如保护膜),这些在粘结之前都要预先去除。为了产生良好的粘结效果,建议使用表面活性剂;

Based on the high quality of the modified PU polymer one-component neutral sealing glue, has the strong stickiness. Used in building, plaza, road as joint sealing material, and car manufacturing, glass installation, electronic seal of filling, submarines and rocket etc.

performance

- superior physical properties

- both viscous and hardness

- start good adhesion, high shear strength after curing

Elastic rubber - 20% of mobility

- do not contain bubbles formula (high temperature and wet application)

- easy to processing

- color stability, strong resistance to UV radiation

application

- sealing and adhesive application of construction industry

The structure of the bond - has flexible demand

Application guide

Dung on the surface:

Bonding material: including all common building materials, such as glass, the pretreatment of wood, PVC, metal, stone and so on.

: bonding layer surface must be clean and contains no dirt and grease;

Must be primer coat: porous surface, no pore smooth surface can be used surfactants.

Suggest a compatibility test before use.

Application:

Methods: manual or pneumatic glue guns

Application: temperature + 5 ° C to + 35 ° C

After cleaning: use before the adhesive curing immediately with  cleanser

Modified processing: form in skin with soap and water before decorate, and repair

Matters needing attention

Coating can be administered, in view of the fact that there are many different kinds of paints and varnishes, however, we suggest do compatibility test before use. Alkyd resin coating systems may require a longer time to dry;

- due to the diversification of bonding layer materials, it is recommended that the compatibility test before the application;

- because in the plastic production process often release chemical reagent, add processing AIDS and other protective agent (such as protective film), all these before bonding will be removed in advance. In order to produce good bonding effect, recommend the use of surfactant;
