Momentive SS4155 General-Purpose Primer for All RTV Silicone Sealants

Momentive SS4155 General-Purpose Primer for All RTV Silicone Sealants

Basic Properties

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.
