    Aerospace Sealants AS157 RTV Sealant is approved as a replacement by the FAA for Momentive RTV157 High Strength Fast Cure RTV Silicone Adhesive Sealant. It has been tested and meets MIL-A-46106 Type I Group III standards.

    AS157 is a high strength acetoxy silicone RTV rubber adhesive that is fast curing at room temperature. It is well suited for applications requiring fast development of physical properties and excellent adhesion. It is one part high temperature silicone that resists weathering, ozone, moisture, and UV when cured. This adhesive works in manual and automatic dispensing equipment. Typical utilization involves dispensing in open air and ambient humidity to result in a high strength adhesive rubber. Cure speed 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 humid environment, results in a cured elastomer condition exhibiting outstanding adhesion.
