What is CIP?

Owatrol CIP (Corrosive Inhibiting Primer) is a rust-inhibiting primer which is suitable for finishing with both single and 2-pack paints and finishes. It contains the anti-corrosive properties of Marine Oil which enable it to stabilize the surface by penetrating deep into the substrate, driving out excess moisture and air to form a solid stable layer.

Why should I use CIP?

Owatrol CIP is easy to use and does not require sand or shot blasting first. It can be used on both new and rusted surfaces – both interior and exterior and is fine for use on horizontal and vertical surfaces. It will not dissolve or break down when even high solvent paints and finishes (urethane, epoxy, chlorinated rubber, synthetic, etc.) are applied to it and the pigmentation provides enhanced protection and perfect film-forming qualities. With Owatrol’s CIP, sand or shot-blasted surfaces do not require immediate priming as a light rust coating will not affect its performance or the final result.

CIP will not break down even when high solvent paints and finishes are applied to it, making it perfect to use as a primer for 2-pack paints. The brick-red pigmentation also provides enhanced protection and film-forming qualities.

CIP’s enhanced corrosion protection and strong surface make it perfect for use in extreme climatic conditions such as in the marine environment and in tropical areas and it has excellent chemical resistance too. Its excellent adhesion means that it also performs exceptionally well on clean, bright steel – typically a difficult surface to coat.

Ideal uses for Owatrol CIP rust-inhibiting primer

  • Outstanding for high performance in severe conditions such as marine or tropical environments
  • Resisting corrosive fumes
  • Protecting motor vehicles
  • Avoiding rusting on construction equipment
  • Protecting ballast tanks of ships
  • Inhibiting rust development on everyday items such as railings and gates
  • Perfect protection where a high resistant paint or two-pack finish is necessary
  • Priming steel superstructures
  • Outstanding adherence on clean bright steel

Application Tools

  • Brush
  • Roller
  • Airless Sprayer (0.4 mm x 80˚ @ 1860-2000psi (128-138 bars))

Surface Preparation

Surfaces must first be clean, dry and free from oil, grease and other surface contaminants. Remove all mill scale; loose and flaking rust and old paint back to a sound surface and edge and feather in any sharp edges.

Any surfaces exposed to chemicals (acids, alkalis or salt deposits) should be washed using copious amounts of water or steam cleaned. Severely contaminated surfaces should be cleaned using an appropriate solvent.

Application of Owatrol CIP Corrosive Inhibiting Primer

Stir well before and during use.

Do not thin.

Applying Owatrol CIP to new surfaces

Prime with 1 coat of Owatrol CIP and allow to dry. For surfaces subject to aggressive climatic conditions apply 2 priming coats.

Applying Owatrol CIP to clean, lightly rusted or new unpainted rusty steel

Apply 2 coats of Owatrol CIP allowing drying time between coats.

Applying Owatrol CIP to old or severely rusted surfaces

Either apply 3 coats of Owatrol CIP allowing drying time between coats or apply ‘wet-on-wet’ applications of Marine Oil until the rust is fully saturated and allow to dry for 24 hours and then apply 2 coats of Owatrol CIP allowing drying time between coats.

Applying Owatrol CIP to previously coated surfaces

First, spot prime all exposed metal with 2 coats of Owatrol CIP allowing drying time between coats and then apply a 3rd coat over the entire area and allow it to dry.

Clean Up

Clean all tools and equipment with white spirit while still wet. If allowed to dry, remove with paint stripper.

NOTE: Any rags, steel wool etc. soaked in CIP may spontaneously catch fire if improperly discarded. Rags, steel wool etc. must be saturated with water after use or placed in a sealed, water filled metal container, before disposing with household waste.

Things to Remember

  • Cover everything you do not wish to paint.
  • Apply between 5˚C (41˚F) and 35˚C (95˚F).
  • Do not apply in direct sunlight or on to hot surfaces.
