Surface preparation for adhesive bonding of metal alloys
Pre-bond surface preparation sol-gel. Improves adhesion of aerospace adhesive bonds and paint on metallic and composite surfaces. SOCOGEL B0102 is a sol-gel using a technology licensed by BOEING. Solgel conversion products are aqueous solutions of zirconium salts activated by an organo-silicon compound, they are particularly effective for surface preparation prior to adhesive bonding. After application and curing the Solgel solution forms a high performance hybrid coating enhancing the adhesion of bonding systems on metals and alloys such as Aluminium, Titanium and Stainless Steel. SOCOGEL B0102 performances comply with current aeronautical requirements and are an interesting alternative to anodizing technologies (chromic, sulphuric...) that are recognised as highly harmful for workers (classification R45: may cause cancer) and which generate increasing waste treatment costs (baths, effluents). SOCOGEL B0102 is more economical in terms of operating costs and effluent treatment. No rinsing is required after application. The product can be dried at ambient temperature.SOCOGEL B0102 is available in the form of 2 component kits, in a colourless version.
