Momentive Siltrust RTV31 Silicone Rubber Compound
High-temperature, two-part silicone elastomer base compound. Requires a curing agent (sold separately).
Momentive Siltrust RTV31 silicone rubber compound is a high-temperature, two-part silicone elastomer base compound. When combined with a curing agent (sold separately), it forms a durable, resilient rubber ideal for various demanding applications. RTV31 offers a room-temperature cure, eliminating the need for specialized equipment or high temperatures. Its solvent-free composition ensures ease of use and a lack of unpleasant odors. The compound demonstrates excellent adhesion with appropriate primers and exhibits exceptional release properties. This versatile material retains its elastomeric properties over a wide temperature range, from -54 C (-65 F) to 260 C (500 F) continuously, withstanding even higher temperatures (up to 316 C or 600 F) for short durations. Its pourable consistency simplifies handling and processing, making it suitable for various molding and casting techniques.
Please note: A curing agent is required and sold separately. Consult the Technical Data Sheet (TDS) for detailed processing recommendations and safety information.
