常见问题(FAQ)

问:工业密封胶主要分为哪几类?

答:常见分为室温硫化硅胶(RTV-1 单组分、RTV-2 双组分)、聚氨酯密封胶与改性硅烷(MS)密封胶等。硅胶耐候耐温好、弹性佳;聚氨酯强度高、耐磨;MS 低气味低 VOC、粘接面广。铭诚锦可依据工况推荐具体体系。

问:单组分与双组分密封胶怎么选?

答:单组分靠湿气或加热固化,操作简便、无需混胶,适合小批量与现场维修;双组分靠 A/B 混合引发固化,可深度固化、速度更快、耐温与力学性能更优,适合大批量自动化点胶。选型取决于产线节拍、胶层厚度与性能要求。

问:密封胶施工前基材需要处理吗?

答:需要。基材表面的油污、脱模剂、灰尘会显著降低附着力。建议用专用清洗剂除油除污,必要时做底涂(primer)处理;对铝合金、工程塑料等低表面能材料,底涂可明显提升粘接可靠性。

问:密封胶固化时间一般多久,受哪些因素影响?

答:单组分 RTV 表干通常数分钟至数十分钟,完全固化 24–72 小时;双组分可在数十秒至数分钟内初固、数小时达使用强度。固化速度受温度、湿度、胶层厚度与配比(双组分)影响,加热可显著加速。

问:汽车/电子用密封胶需要关注哪些环保与认证要求?

答:重点关注低挥发(低 VOC、低雾化物)、无卤、低气味,以及阻燃(如 UL 94 V-0)、RoHS/REACH 等合规要求。铭诚锦代理的瓦克等品牌部分牌号具备 UL、无卤等认证,可按工况提供认证文件。
