单组份 超高强度环氧胶黏剂

实验室开发一种超高强度环氧树脂基单组份胶黏剂,低卤,低粘,高强,耐老化。可以用于金属材料,磁性材料的粘接,1.6mm冷轧钢拉断都不能测出强度。具体一些物理参数如下:
Viscosity
10000cps
Storage Life
3 m (@0~5’C); 12 m (@-20’C)
Curing condition
30min~60min@150’C
Tg
108 ‘C
Tension Strength
65 MPa
Elongation
8.0%
Modulus
2.8 GPa
Halogen content
<900ppm
Hardness
Shore D
88

性能测试结果如下:
