Product Description
Momentive SS4155 is a general-purpose primer designed for use with
any RTV silicone rubber adhesive sealant. As a one-component
product, it requires no mixing and is supplied as a ready-to-use,
easily pourable solvent solution. This primer enhances adhesion to
difficult-to-bond substrates when paired with Momentive's RTV
silicone sealants. It simplifies handling procedures, dries at room
temperature under ambient humidity, and helps ensure reliable
bonding in various applications.
Unique Features
The SS4155 primer features a distinct blue color, facilitating easy
visual inspection for uniform coating application. Its specific
gravity of 0.82 and solids content of 10% contribute to effective
adhesion promotion without requiring complex processing. The flash
point of 37°C (98°F) indicates a relatively safer handling profile
compared to other primers with lower flash points, though it
remains flammable and demands proper safety precautions. A drying
time of 30 minutes is standard, but a minimum relative humidity of
40% is suggested for optimal drying, with a chalky white haze
formation indicating adequate curing. These attributes make it a
versatile choice for ensuring bond integrity in diverse conditions.
Application Scenarios
Momentive SS4155 primer is primarily used to enhance adhesion of
RTV silicone sealants across various substrates, including metals
(e.g., aluminum, steel), plastics, and ceramics, as inferred from
TDS descriptions. It is recommended as a primary or alternate
primer for multiple RTV silicone rubber compounds, such as RTV627
and RTV630, per the Primer Recommendation Table. Based on external
searches for "Momentive SS4155 applications" on industry databases
and manufacturer resources, no specific online sources detailing
exclusive SS4155 application scenarios were found. However, general
industry knowledge suggests it is suited for automotive sealing,
electronics encapsulation, construction bonding, and industrial
maintenance where reliable adhesion under challenging conditions is
required.
