MOMENTIVE RTV159 .
RTV157 and RTV159 are one-component, ready -to-use, high strength silicone rubberadhesive sealants. They cure to tough resilient silicone rubber on exposure to
atmospheric moisture at roomtemperature. RTV159 sealant also provides high temperatureperformance. Both of these products release acetic acid vapors as a byproduct
of cure.
RTV157 and RTV159 sealants are paste consistency products which can be appliedto horizontal, vertical and overhead surfaces in applications requiring high strength
and temperature performance.
Since these adhesive sealants utilize a moisture cure system, they must not be used in thicknesses of greater than 6mm (1/4 in.). Where section depths exceed 6mm
(1/4 in.), Momentive Performance Materials one-component, addition cure or two-component silicone rubber compounds are suggested.
These sealants were not designed for and should not be used for applications intended for permanent implantation into the human body.
