Product Introduction
Momentive SILTRUST™ RTV560-XB is a two-part, non-sag silicone adhesive and sealant engineered for high-strength performance in extreme temperature environments. With a 10:1 mix ratio optimized for meter-mix dispensing, RTV560-XB cures at room temperature or faster with heat, forming a durable elastomer that maintains adhesion and flexibility under thermal cycling. It is widely used in aerospace thermal protection assemblies due to its excellent mechanical strength, solvent-free formulation, and ability to tolerate continuous exposure to high temperatures.
