Description

SS4004P, SS4044P, SS4120, SS4155, and SS4179 primers are formulated for
use with Momentive Performance Materials RTV silicone rubber adhesive sealants.
Momentive Performance Materials’ one-component products offer primerless
adhesion to many substrates. Primers are used to help promote adhesion to
difficult-to-bond substrates. For most Momentive Performance Materials two-component
products, a primer is required when an adhesive bond is needed between the
silicone rubber compound and a non-silicone surface. All primers are
one-component products, requiring no mixing and are supplied ready-to-use as
easily pourable solvent solutions.

SS4004P and SS4044P primers help promote adhesion to metals (such as
aluminium, copper. steel, stainless steel, brass, and galvanized metals),
porous materials, unglazed ceramics and wood. SS4004P primer is bright pink,
providing easy visual determination of uniform coating. SS4044P primer is
virtually identical to SS4004P primer, but is designed for applications where
discoloration of the substrate is undesirable.

SS4120 primer helps promote adhesion of Momentive Performance Materials
addition cure RTVs and is used where clarity is needed. SS4155 is a general
purpose primer for use with any RTV.
