What kind of glue is used to bond silicone feet?
10 Dec 2025
The bonding of silicone rubber feet requires selecting the appropriate adhesive based on material characteristics, usage scenario, and process requirements. Below are specific recommendations and analyses:
I. Silicone-Specific Adhesive (Preferred Option)
Recommended Type:
Silicone-to-silicone adhesive (e.g., KL-301AB, KN-300, etc.)
The surface must be clean and dry; if necessary, wipe away oil stains with alcohol.
Some adhesives require mixing in a specific ratio (e.g., AB glue), stirring thoroughly before application.
Curing time varies depending on the adhesive type (fast-drying types: minutes to hours; slow-drying types: 24 hours or more).
Features: Specifically designed for silicone, high bonding strength, high temperature resistance (typically -60℃ to 200℃), water resistance, chemical corrosion resistance, good flexibility after curing, and not prone to cracking.
Applicable Scenarios: Foot pads that need to withstand long-term pressure, friction, or high-temperature environments (e.g., car floor mats, industrial equipment floor mats). Operating Instructions: Silicone adhesive specifically for bonding metal/plastic (e.g., 460 glue)
Features: High strength and good weather resistance for bonding silicone to metals (e.g., stainless steel, aluminum alloy) and plastics (e.g., ABS, PC).
Applicable Scenarios: Situations where feet need to be fixed to metal or plastic bases (e.g., anti-slip mats for electronic devices).
Note: Some adhesives may be corrosive to plastics; compatibility testing is required beforehand.
II. General-Purpose Adhesives (Alternative Solutions)
CL-14A Silicone Double-Sided Adhesive Treatment Agent
Product Model: CL-14A
Packaging Specifications: 1L/bottle, 3KG/drum, 15KG/drum;
Bonding Process: Treat silicone surfaces at room temperature;
Product Characteristics: Significantly enhances silicone surface activity and improves adhesion;
Suitable Materials: Surface treatment of elastic materials such as silicone rubber (silicone rubber, silicone);
Common Applications: Silicone feet, silicone ornaments, etc.
Epoxy Resin Adhesive (AB Glue)
Features: High bonding strength, resistant to chemical corrosion, but long curing time (several hours to 24 hours).
Suitable Scenarios: Scenarios requiring high strength but not requiring rapid curing (such as industrial equipment feet).
Note: Relatively hard after curing, poor flexibility, not suitable for feet requiring frequent bending.
UV Adhesive (Ultraviolet Curing Adhesive)
Features: Fast curing speed (a few seconds to a few minutes), high transparency, suitable for optical-grade bonding.
Disadvantages: Requires UV irradiation equipment; high requirements for silicone surface treatment.
Applicable Scenarios: Transparent silicone feet or production lines requiring rapid curing.
III. Selection Recommendations
Based on Material:
Silicone to Silicone: Prioritize silicone-specific adhesives (e.g., KL-301AB).
Silicone to Metal/Plastic: Choose 601 adhesive or Kanglibang silicone-specific adhesive (compatibility testing required).
Rapid Positioning: Choose instant adhesives (requires a treatment agent).
Based on Usage Environment:
High Temperature Environment: Choose high-temperature resistant silicone adhesives (e.g., KN-300, 200℃).
Humid Environment: Choose waterproof adhesives (e.g., silicone-specific adhesives or epoxy resin adhesives).
Frequent Bending: Choose flexible adhesives (e.g., silicone-specific adhesives).
Ease of Operation:
Manual Operation: Choose fast-drying adhesives or one-component silicone adhesives (e.g., some room temperature curing types).
Automated Production: Choose UV adhesives or two-component adhesives (can be used with a dispensing machine). IV. Precautions
Surface Treatment: The silicone surface must be clean and dry. If necessary, sand it or apply a treatment agent to enhance adhesion.
Trial Bonding Test: Before large-scale use, test bond on a small area to confirm the bonding strength and weather resistance.
Safety Precautions: Some adhesives contain organic solvents or hardeners. Wear gloves and a mask during operation to avoid skin contact or inhalation of volatile substances.
Storage Conditions: The adhesive must be stored in a sealed container, avoiding high temperatures or direct sunlight. Some adhesives require refrigeration.
