Description

RTV157 and RTV159 are one-component, ready-to-use, high strength
silicone rubber adhesive sealants. They cure to tough resilient silicone rubber
on exposure to atmospheric moisture at room temperature. RTV159 sealant also
provides high temperature performance. Both of these products release acetic
acid vapours as a by-product of cure.

RTV157 and RTV159 sealants are paste-consistency products which can be
applied to horizontal, vertical and overhead surfaces and 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.
