Product Introduction
This product cures upon exposure to atmospheric moisture at room temperature, releasing acetic acid vapors as a by-product to form a durable, weather-resistant silicone rubber layer. It offers excellent electrical insulation properties, chemical resistance, and low-temperature flexibility, operating without additional heating or equipment. The curing process is influenced by environmental humidity and temperature, with higher conditions accelerating cure and low temperature/dryness slowing it down.
Advanced Properties
Building on its basic attributes, RTV102’s paste consistency enables application on vertical and overhead surfaces without sagging, overcoming limitations of self-leveling sealants. It supports rapid curing at room temperature (tack-free time approximately 20 minutes) and maintains performance across a wide temperature range from -60°C to 204°C. Additionally, the product features self-adhesion properties, bonding well to various clean substrates like metals, glass, and ceramics without primers, but thickness must not exceed 6mm to avoid curing issues.
Application Scenarios
RTV102 is suitable for general-purpose bonding, sealing, electrical insulation, and formed-in-place gaskets, particularly for application on vertical or overhead surfaces.
