Product Description

KA003-3 is a two-component acrylic-based adhesive that cures at room temperature without requiring special surface treatment. It offers strong adhesion to low-surface-energy materials such as polypropylene (PP), polyethylene (PE), and thermoplastic polyolefin (TPO). This adhesive can replace mechanical fasteners, plastic welding, and chemical pretreatment processes, making it suitable for various bonding applications.

Key Features

  • Excellent adhesion to PP, PE, TPO, and other plastics
  • No need for surface pretreatment
  • Solvent-free formulation with low odor
  • Good chemical and water resistance
  • Compliant with 2011/65/EU RoHS regulations
  • Meets environmental safety standards (chlorine < 900 ppm, bromine < 900 ppm, chlorine + bromine < 1500 ppm)

Recommended Applications

  • Structural bonding of thermoplastic polyolefin (TPO)
  • Adhesion of difficult-to-bond materials without surface pretreatment
  • Replacement of screws, rivets, and plastic welding in various applications
