Application

Sikaflex®-545 is especially designed for applications which require a very high initial grab and a broad adhesion range. Suitable substrate materials include timber, glass, metals, metal primers and paint coatings (two-part systems), ceramic materials and plastics.

Description

A low emission single-component silane terminated polymer (STP) assembly adhesive. It has a unique high initial grab with high load capacity and excellent workability. It bonds well to a wide range of substrates with minimal pre-treatment.

Features and benefits:

  • Powerful initial grab.
  • Very low emission.
  • Bonds well to a wide variety of substrates without the need for special pre-treatments.
  • Excellent workability.
  • Free of isocyanate, solvent and phthalate.
  • Meets highest EHS standards.
  • EC1 certificate.
