Rongtai RT-308 Silicone Rubber Sealant
Rongtai RT‑308 Silicone Sealant 300ml
What it is
Rongtai RT-308 is a one-component silicone sealant (often grouped with models like RT-388) that cures at room temperature into a flexible rubber.
This type of sealant belongs to RTV (room-temperature vulcanizing) silicone, meaning it hardens when exposed to air moisture.
Features
Strong adhesion to materials like glass, tiles, aluminum, plastics, and metals
Waterproof & mold-resistant (good for wet areas)
High-temperature resistance
Flexible after curing (won’t crack easily)
Typically available in 300 ml cartridges and different colors
Common Uses
You can use it for:
Sealing windows, doors, and aluminum frames
Bathroom joints (sinks, bathtubs, tiles)
Fixing cracks or gaps in walls
Glass and mirror installation
Light electrical insulation and gasketing
It’s basically a general-purpose construction sealant.
Drying / Curing
Skin formation: ~30–60 minutes
Full cure: about 24–48 hours depending on thickness and humidity
