Product Introduction
Momentive SNAPSIL™ RTV230 A/B is a two-component, fast-curing silicone adhesive designed for rapid green strength development and reliable primerless adhesion. Its room-temperature cure makes it ideal for heat-sensitive substrates, while its 10:1 convenient mix ratio and thixotropic consistency support efficient automated dispensing. With excellent electrical insulation properties and broad thermal stability, RTV230 A/B is engineered for industrial bonding applications requiring productivity, durability, and consistent performance.
