Dhanya’s expertise in manufacturing specialty adhesive-coated foams, can provide tailored solutions for demanding applications where specific foam properties and a reliable adhesive bond are required.
Adhesive coating is done on foam sheets to facilitate fixing of the end part easily on the application area. Adhesive coating can be done on all materials including PU foam, EPDM closed cell and semi-closed/open cell Foam, Nitrile Foam, CR Foam, PE and EVA foam sheets. Our adhesive coating process is a unique process and gives a very good bonding strength between adhesive and material.
Advantages of Using Adhesive-Coated Foams
- Easy to use: The adhesive coating simplifies the application process.
- Strong and durable bonds: Provides a secure and long-lasting attachment.
- Versatile: Can be used on a variety of surfaces.
- Clean and efficient: Eliminates the need for messy liquid adhesives.
- Customizable: Foams and adhesives can be tailored to specific needs.
- Improved aesthetics: Eliminates the need for visible mechanical fasteners.
- Gap filling and sealing: Foam can conform to uneven surfaces and create a tight seal against air, water, or dust.
- Cushioning and vibration damping: Protects against damage and reduces noise.
- Insulation: Provides thermal or acoustic insulation.
Frequently Asked Questions
Adhesive coating involves applying a layer of adhesive (e.g., glue, tape, or spray) to foam surfaces to enable bonding, sealing, or mounting. It’s used in industries like packaging, automotive, and construction.
- Bonding: Attach foam to other materials (metal, plastic, fabric).
- Sealing: Create airtight/waterproof barriers.
- Mounting: Secure foam in place without mechanical fasteners.
- Pressure-Sensitive Adhesives (PSA): Peel-and-stick tapes or films.
- Hot Melt Adhesives: Thermally activated for strong bonds.
- Spray Adhesives: Even coating for large surfaces.
- Silicone Adhesives: Flexible and heat-resistant.
Common methods include:
- Roll Coating: Adhesive rolled onto foam sheets.
- Spraying: For uniform, thin layers.
- Lamination: Bonding adhesive films to foam.
Silicone or epoxy-based adhesives handle -40°C to 140°C, while standard PSAs may degrade above 80°C.
Closed-cell foams (e.g., EPE, XLPE) with waterproof adhesives (e.g., acrylic) resist moisture. Open-cell foams may require additional sealing.
Durability depends on:
- Adhesive Type: High-tack PSAs > temporary adhesives.
- Surface Prep: Clean, dry foam improves adhesion.
- Application: Industrial coatings last years; consumer-grade may degrade faster.
Yes. Water-based, solvent-free, or biodegradable adhesives (e.g., starch-based) reduce environmental impact.
- Packaging: Protective padding with peel-and-stick backing.
- Automotive: Soundproofing and vibration damping.
- Construction: Insulation panels with adhesive seals.
- Medical: Sterile adhesive foam for device padding.
Recyclability depends on adhesive type. Water-soluble adhesives simplify recycling, while thermoset adhesives may require separation.
