GE SS4179 Primer per 1 Pint

SS4179 Primer is formulated for use with Momentive Performance Materials RTV silicone rubber adhesive sealants. Momentive Performance Materials single-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 single-component products requiring no mixing and are supplied ready-to-use as easily pourable solvent solutions.

Application

• GE construction primers enhance adhesion of GE construction products to difficult-to-bond surfaces and substrates

SS4179 Primer is a candidate for adhesion promotion on: various factory applied paints including; fluoropolymer, acrylics, alkyds, powder coats, etc., most plastics, conversion-coated & painted aluminum, copper and brass. SS4179 is also effective on some porous substrates. SS4179 primer may be suitable for some food contact applications where FDA regulations apply. Determination of specific requirements is recommended prior to use.

Most typical applications require only a few minutes of drying time prior to application of the sealant (drying time is variable and dependent upon local conditions at point of use). See typical properties table for drying times.

These silicone primer solutions are compatible with all GE branded construction silicone products lines. Consult Technical Services for specific sealant-primer-substrate recommendations or testing.
