Product Description

KA003 is a two-component acrylic-based adhesive that cures at temperatures between 14–34°C without requiring additional surface treatment. It provides excellent adhesion strength to low-surface-energy substrates such as polypropylene (PP), polyethylene (PE), and thermoplastic polyolefin (TPO). The adhesive can replace mechanical fasteners like screws and rivets, as well as plastic welding and chemical pretreatment processes.

Key Features

  • Outstanding operability after mixing
  • Strong adhesion to various substrates
  • Structural bonding capability for thermoplastic polyolefin (TPO)
  • No surface pretreatment required
  • Excellent chemical and water resistance
  • Compliant with 2011/65/EU RoHS regulations

Recommended Applications

  • Bonding of PP, PE, TPO, and other low-surface-energy materials
  • Structural applications requiring strong adhesion without mechanical fasteners
  • Applications where chemical etchants, primers, or surface treatments need to be avoided
