Technical Information
Momentive RTV88/DBT is a two-part, condensation-cure silicone rubber compound catalyzed by dibutyltin dilaurate (DBT). When the base and catalyst are combined at the specified ratio, the system cures at room temperature to a firm, stable silicone rubber elastomer suitable for mold making, casting, potting, and the fabrication of custom silicone gaskets and seals. The cured RTV88 rubber exhibits high tear strength, excellent thermal stability, and resistance to oils and chemicals, making it a reliable industrial silicone compound for demanding fabrication and sealing applications requiring a pre-formed or cast silicone component.
Why Choose RTV88/DBT?
- ✅ Two-Part System — Mix base and DBT catalyst for controlled, reliable cure
- ✅ Mold & Cast Grade — Ideal for silicone mold making, casting, and custom gasket fabrication
- ✅ High Tear Strength — Durable cured rubber for demanding mechanical applications
- ✅ Chemical Resistant — Resists oils, solvents, and industrial fluids after cure
- ✅ 1 lb Kit Format — Right quantity for lab, prototype, and small-batch production work
