Sika Aktivator-205 is a professional-grade solvent-based adhesion promoter designed to enhance bonding performance between substrates and Sika sealants or adhesives. This colorless, transparent formula reacts with moisture to deposit active chemical groups on surfaces, creating a molecular bridge that significantly improves adhesion strength and durability.

Key Features:

• Solvent-based clear formula for invisible application
• Enhances adhesion on metals, plastics, ceramics, and painted surfaces
• Fast flash-off time for improved workflow efficiency
• Easy application with simple wipe-on method
• Specifically formulated for use with Sikaflex and Sikasil product lines

Applications:

Ideal for treating non-porous substrates prior to applying Sika adhesives and sealants in automotive, marine, industrial, and construction applications. This activator is essential when bonding to challenging surfaces that require enhanced adhesion performance. Recommended for professional use only—always perform substrate compatibility testing before full-scale application, especially on materials susceptible to stress cracking.
