An accelerator to improve the rate of cure of viscous, gap-filling cyanoacrylate adhesives (superglues). CYANOACRYLATE ACCELERATOR improves bonding to difficult surfaces such as slightly acidic materials, prevents penetration of adhesive into porous materials, and improves the cure of adhesive fillets. SOUDAL CYANOACRYLATE ACCELERATOR can be used with the SOUDAL range of cyanoacrylate adhesives. Speeds strength development to permit immediate use of the part. Solvent based aerosol spray that activates superglue and is non-yellowing, reducing bloom and odour.
