A Grey RTV 15 g is a grey-colored, one-component RTV (Room‑Temperature Vulcanizing) silicone sealant / gasket maker, packaged in a small 15‑gram tube. It cures at ambient temperature when exposed to moisture in the air, forming a flexible silicone elastomer that acts as a sealant, adhesive, or formed-in-place gasket.
Property | Typical Behavior / Value | Comments |
---|---|---|
Curing Mechanism | Moisture-cure (RTV) | No mixing needed; cures from outer surfaces inward |
Appearance (uncured) | Grey paste / semi-viscous | Helps it blend somewhat with metal or industrial surfaces |
Temperature Range | Roughly –50 °C up to ~200–250 °C (varies by formula) | Good for many automotive and mechanical environments |
Flexibility & Elasticity | Capable of elongation, low shrinkage | Helps absorb vibration and thermal expansion |
Adhesion / Substrate Compatibility | Bonds to metals, many plastics, painted surfaces | Surface prep (cleaning, degreasing) is important for good adhesion |
Chemical Resistance | Resistance to oils, water, antifreeze, common fluids (depending on formulation) | Some formulas are optimized for engine environments |
Skin / Tack-Free Time | Minutes (e.g. 5 to 10 min or more) depending on humidity & thickness | After the surface skins over, curing continues inward |
Cure Time / Full Cure | Several hours to 24 hours (or longer for full thickness) | For certain thicknesses, full cure might take up to 48 hours |
Non‑corrosive / Sensor Safe | Many grey RTVs are neutral or non‑acid curing to avoid harming sensitive parts | Preferred in applications where metals or electronics are involved |
Package / Size | 15 g tube, often for smaller jobs or touch-ups | Handy for small repairs or gasket re-sealing |
