SOCOGEL A0203 BLUE is an aqueous solution of zirconium salts, activated by an organo-silicon compound. After application, the solution forms a high performance sol-gel hybrid coating, which enhances the adhesion of paint systems on metals and alloys such as aluminium, titanium, stainless steel.

SOCOGEL A0203 BLUE main characteristics :

  • is a patented technology
  • enhances painting adhesion and durability of most of the current paint systems
  • is designed to solve the rivet rash issue
  • is a chromium free conversion product - an interesting alternative to highly harmful chromate conversion technologies
  • is a potential process cost saving  as no rinsing is required after application (no rinsing process, neither effluent treatment)
  • is blue to visualise the product when applied.

SOCOGEL A0203 BLUE  increases adhesion of  primers and epoxy based paints on metallic surfaces . These coatings could be water or solvent-based, high solids content primers or paints, chromated or non-chromated paint system. 
SOCOGEL A0203 BLUE is specially adapted to reactivate basic primer before applying the epoxy primer and to enhance paint system adhesion. It is compatible with composite materials.
It is designed for both OEM and MRO during airframe maintenance operations.

  • Two-component product : one part C and one part EC
  • Dispense Part C into part EC.
  • Depending on the kit size, mix or shake thoroughly for a minimum of 30 seconds. For kits exceeding 1 litre, use a clean mixer. For 30L drums, Kremlin Cyclix mixer is recommended.
  • Allow the solution to induct for a minimum of 30 minutes. Remix prior to application.

WARNING! the two parts must be free of precipitates. If not, the material must be rejected. The original packaging must be perfectly closed. SOCOGEL A0203 BLUE is a two-component product with a limited shelf life. These are single-use kits.


  • Mask components areas not to be painted (windows, probes…) with suitable materials (eg adhesives tapes, masking papers...).
  • Mask high strength steel parts as landing gears to prevent any contacts with liquid SOCOGEL A0203 during the application.   
  • Clean the area to be painted with DIESTONE DLS wipes. 
  • Abrade the area to be paint with scotch brite or fine abrasive paper (Paper 240 grit or fine/Sans paper grade P 320). 
  • Note 1 : a perfect abrasion on rivets is required to prevent rivet rash.  
  • Clean the surface with DIESTONE DLS wipes and allows drying.
  • Note 2 : if the time between the end of the surface preparation and the application of the sol gel is over 2 hours, or if the area is dusty use tack rag to remove dust.
  • Mix thoroughly the two part material and let react 30 minutes at room temperature.

SOCOGEL A0203 BLUE can be applied by spraying, brushing, dipping or wiping.

Note : Apply SOCOGEL A0203 BLUE within 24 hours of deoxidising. Protect coated surface from contamination if the primer or paint is not applied straight after the SOCOGEL treatment.

By spraying: 

  • Stainless steel spray guns are recommended such as
    •  Gravity SATA jet 5000B or KREMLIN MG22G-HPA with following parametersNozzle size: 1.3 mm & Air pressure:  5/6 bars & Application distance: 1.25+/-0.25 meter
    • Any equipment including HVLP – AIRLESS - AIRMIX – Hand pumps, sprayers… selected after trials.
  • Method: spray a thin coat to avoid runs in just wetting the surface. Let dry 60 minutes. After drying the blue visual color allows a visual inspection.   
  • Apply the primer within 11 hours after drying. 

By wiping: use only SOCOSAT PPA60 (29x42 cm) wipes. Take one new pouch of wipes and pour 1L of mixed SOCOGEL A0203 BLUE into it. Be sure that all wipes are homogeneously saturated before applying.

If wettability troubles occur, this reveals bad surface preparation. 

For any application, allow to dry for about 1 hour before applying the primer/paint system
