Momentive RTV566 Silicone Rubber Compound 1.1Lb Kit

Description

Momentive RTV566 Silicone Rubber Compound 1.1Lb Kit

Momentive RTV566 Silicone Rubber Compound is a two-component red silicone system engineered for vacuum, aerospace, and electronics applications where low outgassing and dimensional stability are critical.

The RTV566A base and RTV566B catalyst combine in a 100:0.1 ratio by weight, forming a high-strength, high-temperature silicone elastomer. Once cured, it exhibits excellent adhesion (with primer), superior release characteristics, and consistent mechanical performance across extreme thermal cycles.

This product has been extensively used in satellite components, optical assemblies, high-voltage insulators, and spacecraft encapsulation, where material purity and thermal endurance are essential.

The compound maintains flexibility and insulation under severe environmental conditions — including exposure to vacuum, radiation, shock, and vibration — making RTV566 a preferred choice for critical aerospace and defense sealing applications.

Uses of the Product

• High-vacuum applications requiring low outgassing materials.

• Electrical and electronic encapsulation in aerospace systems.
