What kind of glue is used to bond silicone to fabric?

When bonding silicone to fabrics, the appropriate adhesive type should be selected based on specific requirements (such as bond strength, temperature resistance, water resistance, and environmental friendliness).

Below are some commonly used adhesive solutions and applicable scenarios for reference:

1. KN-300N Waterproof Silicone Adhesive (Recommended First Choice)

Type: Single-component or two-component silicone adhesive (such as RTV silicone adhesive, silicone liquid).

Features: KN-300N is a slow-drying adhesive. This slow-drying silicone adhesive is used for bonding silicone to silicone at room temperature. It is easy to apply and provides a strong bond.

High Compatibility: Specifically designed for silicone, it has good bonding performance with fabrics (such as cotton, polyester, nylon, etc.).

Temperature Resistance: Withstands temperatures from -60℃ to 200℃ (some models are even higher), suitable for high or low temperature environments.

Water Resistance: Waterproof and moisture-proof, suitable for outdoor or humid environments.

Elasticity: Soft and elastic after curing, suitable for fabrics that need to be bent or stretched (such as clothing and shoe materials). **Application Scenarios:** Adhesive bonding products are medical-grade safety certified. Typical applications include various silicone seals, insulation of various electronic components, and miscellaneous silicone parts.

2. **Polyurethane Adhesive (PU Adhesive)**
Features:
Good flexibility: Soft and elastic after curing, suitable for fabric bonding.
Water resistance: Excellent waterproof performance, suitable for outdoor products.
Environmental friendliness: Some models meet environmental standards (e.g., solvent-free).

Application Scenarios: Bonding silicone to fabric (e.g., sports protective gear, rain gear, shoe materials).

Recommended Brand: Kanglibang

3. **Liquid Hot Melt Adhesive**
Features:
Fast curing: No solvent required, direct application.
Low cost: Suitable for small batches or temporary bonding.

Poor temperature resistance: Easily softens at high temperatures and easily cracks at low temperatures.

4. **Instant Adhesive (Fast-drying Adhesive)**
Types: Such as Kanglibang 601, etc.
Features:
Fast curing: Cures in seconds to minutes.
High strength: However, it is brittle and easily detached upon impact.

Poor temperature resistance: Easily decomposes at high temperatures.

Suitable scenarios: Quick bonding of small areas (e.g., bonding silicone buttons to fabric), but requires a pretreatment agent.

Selection recommendations:
Prioritize silicone-specific adhesives: For long-term bonding and flexibility requirements, choose single-component or two-component silicone adhesives.

High strength requirements: Choose epoxy resin adhesives (AB adhesives), but flexibility will be sacrificed.

Outdoor or waterproof scenarios: Choose polyurethane adhesives or silicone-specific adhesives.

Temporary or low-cost requirements: Choose liquid hot melt adhesives or instant adhesives.

Choosing the appropriate adhesive based on specific needs ensures a strong and durable bond.
