产品描述
Product Description

AA-69是一种单组分、高强度、室温快速固化的耐高温硅橡胶。它适用于快速实现优异粘接性能并达到物理指标的情形。AA-69在目前所有脱乙酸基固化的产品中，耐高温的能力最强。固化后的弹性体能抵御气候、臭氧、潮湿、紫外线及高温。AA-69适用于手工操作及自动设备。
AA-69 is a high strength, high temperature silicone RTV engineered for applications requiring fast development of physical properties and excellent adhesion. AA-69 offers the highest temperature resistance of any acetoxy cure silicone currently available. When cured, the elastomer resists weathering, ozone, moisture, UV and high temperatures. AA-69 works well in manual and automatic dispensing equipment.

关于固化
Heat Accelerated Curing

热风可以大幅提高固化速度并立即实现粘接效果。一分钟热风吹送后再经一分钟湿度条件下冷却，即可固化并形成优异的粘接性能。
Cure speeds can be accelerated with hot air to nearly instant cures exhibiting very fast adhesion. A one minute hot air stream exposure, followed by a one minute cool down in a humid environment, results in a cured elastomer exhibiting outstanding adhesion.
