Features & Benefits
- Single-component, neutral curing, room-temperature vulcanizing (RTV) silicone sealant
- With an excellent temperature range (-50°C to 250°C) and high elasticity, it can form a durable chemical bond between the tire rubber and the sound-absorbing cotton, resulting in a significant bonding effect.
- It boasts excellent weather resistance, including resistance to ozone, UV radiation, aging, and chemical corrosion (acids, alkalis, and oils), ensuring long-term use without significant degradation.
- Easy to operate, avoiding damage to the noise-dampening layer caused by traditional tire repair methods.
Applications
The bonding and fixation of sound-absorbing cotton to the tires of passenger cars, new energy vehicles, commercial vehicles, buses, racing cars, off-road vehicles, and other types of vehicles.
Typical Properties
| Property | Typical Value | Description |
| Extrudability (s) | 1.5 | Ensures smooth dispensing; suitable for manual or sealant gun application. |
| Hardness (Shore A) | 30 ~ 50 | Maintains flexibility; compatible with the elasticity of tire rubber. |
| Elongation at Break | 250% ~ 320% | High elasticity prevents cracking during tire deformation. |
| Tensile Adhesion Strength (MPa) | 1.06 | Meets the internal stress requirements of the tire. |
| Temperature Resistance Range | -50°C ~ 250°C | Suitable for extreme climates and heat generated during high-speed driving. |
| Tack-free Time (min) | 30-50 | Curing time at room temperature to ensure optimal bonding strength. |
| Application Temperature Range | 5°C ~ 40°C | Optimal ambient temperature for sealant flow and curing rate. |
