Resin

Silent cotton adhesive

Features & Benefits

1.Single-component, neutral curing, room-temperature vulcanizing (RTV) silicone sealant.
2.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.
3.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.
4.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

Parameter	Typical Value	Description
