3m胶带9448a
在室温和50%相对湿度条件下，原包装状态下自生产之日起保存期为12个月
应用技术
3m9448a粘接强度随胶粘剂与被粘表面接触面积的增大而增加，施加稳定的压力有助于胶粘剂与被粘表面的接触，从而加大粘接强度。要达到最佳的粘接效果，粘接表面必须是洁净、干燥的，胶带应用的最佳温度范围是21-38℃,建议若初始粘接温度低于10℃时，不适于粘接，因此时的胶粘剂太硬，而无法牢固的粘接在物体上；但是，如果已经粘接上了，低温下的持粘力同样是令人满意的。
产品应用
3m9448a在环保方面符合rohs法规要求，经过ul环保认证等特征。广泛用于加工行业，包括橡塑行业中橡胶条及塑料的粘结，适用于冰箱蒸发器及控制面板粘结、铭牌粘结、家用电器、汽车、手机、海棉、纸品、玩具和电子仪器零件组装
3m tape 9448a
under the condition of room temperature and 50% relative humidity, the preservation period is 12 months from the date of production
applied technology
the bonding strength of 3m9448a increases with the increase of the contact area between the adhesive and the adhesive surface, and the stable pressure is helpful to the contact between the adhesive and the adhesive surface. to achieve the best effect of bonding, bonding surface must be clean, dry, the best temperature range of the application of adhesive tape is 21-38 deg c, if the initial bonding temperature lower than 10 deg c, not suitable for bonding, because the adhesive is too hard, but not firmly bonded on the object; however, if you have bonding. stick to low temperature is also satisfactory.
