How to choose the best silicone for webbing?

When you get the webbing,you need check the webbing content.If it's polyester webbing,you can use two-parts silicone or one part silicone.Alcohol-releasing liquid silicone rubber is your best choice.It's eco-friendly,less odor.The silicone product can stick strongly on webbing after cured.It can be cured by atmospheric moisture.You must keep production site with moisture 55-60%RH.If it's nylon webbing,you'd better use Acid-releasing LSR.The silicone has much better sticky force than other silicone ink.

Single-component, moisture-curing liquid silicone for webbing (dispensing/anti-slip coating)

✅ Optimal relative humidity: 50%–65% RH (recommended stable control at 55–60% RH); ambient temperature: 22–28°C (commonly 25°C)

- Below 45% RH: Insufficient moisture leads to slow curing, a tacky surface, and incomplete internal curing (uncured core/sandwich effect); this issue is most common in winter.

- Above 70% RH: Excessive humidity causes rapid surface skinning, bubbling, and pinholes; adhesion between the webbing and silicone deteriorates, and water droplets may condense on the silicone surface.

Distinction:

👉 Moisture-curing (Single-component RTV-1; commonly used for webbing dispensing): Cures via atmospheric moisture; humidity control is essential (the 50–65% RH range mentioned above applies here).

👉 Two-component, room-temperature addition-cure liquid silicone: Does not rely on moisture; cures after mixing components A and B; minimally affected by ambient humidity; no need for intentional humidification.

Key Production Points (Webbing Factory Operations)

1. Silicone coatings on webbing are typically very thin (0.2–0.8 mm). In an environment of 55% RH and 25°C, the surface dries to the touch in about 3–8 minutes, with full cure achieved in 24 hours.

2. If humidity is too low: Use a misting system in the curing room. If humidity is too high: Use industrial dehumidifiers.

3. Avoid rapid humidification; if the surface layer dries and seals too quickly, moisture cannot penetrate to the bottom layer, leaving the interior soft and tacky, which increases the defect rate.
