RTV stands for Room‑Temperature Vulcanizing silicone. It cures at room temperature when exposed to moisture in the air.
“Black RTV” refers to the color and formulation (black silicone) — often reinforced or modified to handle higher stresses, oil exposure, temperature cycling, etc.
“15 g” is the mass (gram quantity) of the product in the tube — a small cartridge or tube suitable for light or spot repairs (e.g. valve covers, small sealing surfaces).
Property | Typical Range / Behavior | Purpose / Insight |
---|---|---|
Temperature resistance | ~ –60 °C to ~250‑300 °C (sometimes intermittent up to 315 °C) SANVO+4SupplyVan+4SANVO+4 | To survive engine heat, exhaust environment, and thermal cycling |
Flexibility & elasticity | High elongation (e.g. ≥ 200 % or more) and low shrinkage | To maintain the seal under vibration, expansion, contraction |
Oil / fluid resistance | Resistant to motor oil, gear oil, coolant, antifreeze, transmission fluid, etc. SANVO+3Synlube+3SANVO+3 | Because often used in engine and transmission interfaces |
Curing / skinning time | Skin forms in minutes; full cure in hours (often 24 h) | The surface “skins over” first, then the interior cures more slowly |
Non‑corrosive / sensor safe formulation | Many modern RTVs are neutral cure or non‑acidic so they don’t damage sensors or metals | Important for modern engines / electronics |
Adhesion / sealing | Bonds to metal, some plastics, painted surfaces, etc. | To form “formed-in-place” gaskets where a flat gasket may not suffice |
Durability | Resistant to aging, weathering, vibration, thermal cycling | So the seal does not crack, migrate, or fail prematurely |
