PAIHO Solvent & Heat Activated Hook & Loop: A No-Sew Solution for Various Industries

Skip the sewing! PAIHO® offers no-sew hook and loop fasteners as an alternative to buttons, zippers, and snaps. Choose from solvent-activated (SA), radio frequency (RF), or iron-on DT-1 options.

1. Solvent Activated (SA) Hook & Loop: The Chemical Bond

Solvent Activated (SA) hook and loop features a dry adhesive coating that is activated by a solvent, typically MEK (methyl ethyl ketone). This chemical reaction creates a strong bond, effectively replacing the need for sewing. SA hook and loop is well-suited for applications involving PVC/Vinyl substrates.

  • Key Features:
    • Solvent-activated dry adhesive coating
    • Designed as a no-sew solution
    • Strong bond on compatible substrates
  • Ideal Applications:
    • Bonding hook and loop to PVC/Vinyl products (e.g., tarps, banners, upholstery)

2. Radio Frequency (RF) Hook & Loop: The High-Tech Fastener

RF hook and loop offers a reliable fastening solution by combining hook and loop with the precision of radio frequency (dielectric & ultrasonic) adhesion. This technology creates a strong, durable, and often water-resistant bond. It’s capable of withstanding repeated use thanks to its high cycle life.

  • Key Features:
    • RF (Dielectric & Ultrasonic) adhesion
    • High cycle life
    • Water-resistant
    • Bonds to a wide range of substrates
  • Ideal Applications:
    • Marine applications (e.g., boat covers, sails)
    • Inflatables (e.g., rafts, air mattresses)
    • Medical devices (e.g., braces, supports)
    • Tents and awnings

3. Iron-On DT-1: The Heat-Seal Option

Iron-on DT-1 hook and loop utilizes heat to create a bond, offering a convenient no-sew alternative. It can be applied using either RF or thermo-compressing methods. The strength of the bond depends on the fabric thickness, and it’s important to note that Iron-On DT-1 is washable.

  • Key Features:
    • Applied using RF or thermo-compressing
    • Non-stitch, washable
    • Bonding effect varies with fabric thickness
    • Special orders may be required
  • Ideal Applications:
    • Polyester back cloth
    • PU/TPU leather (e.g., carpet backing, curtains)
    • Elastic fabric
