Sikaflex 252 Elastic Adhesive for Vehicle Assembly Bonding

Sikaflex 252 Elastic Adhesive for Vehicle Assembly Bonding Overview

Sikaflex 252 is a one-component polyurethane adhesive designed specifically for vehicle assembly, providing excellent adhesion to large components subjected to dynamic stresses. This moisture-curing elastic adhesive bonds well to metals, GRP, ceramics, and plastics, making it ideal for applications in automotive manufacturing and other industries. With good gap-filling properties, vibration-damping characteristics, and electrical non-conductivity, Sikaflex 252 ensures reliable performance in demanding environments. It is listed under NSF – Proprietary Substances and Nonfood Compounds.

Sikaflex 252 Features and Benefits

• Strong Dynamic Stress Resistance: Ideal for bonding components subject to vibration and movement.
• Versatile Substrate Bonding: Adheres to timber, metals, ceramics, and plastics.
• Effective Gap-Filling Properties: Ensures secure bonding on uneven surfaces.
• Vibration-Damping: Reduces noise and enhances assembly stability.
• Paintable: Achieves a professional finish with minimal effort.
