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 enables it to stabilise the surface by penetrating deep into the substrate, driving out excess moisture and air to form a solid stable layer.
CIP is easy to use and does not require sand or shot blasting first. It can be used on both new and rusted 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 Marine 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.
Ideal uses for Marine CIP rust inhibiting primer
- Outstanding for high performance in severe conditions such as marine or tropical environments
- Resisting corrosive fumes
- Protecting ballast tanks of ships
- Perfect protection where a high resistant paint or two-pack finish is necessary
- Outstanding adherence on clean bright steel
Restrictions
- Caution if using Novol Protect 360 Epoxy.
- One coat CIP maximum.
- Always check for compatibility.
Surface Preparation
General Directions
- Surfaces must be clean, dry, and free from oil, grease and other surface contaminants.
- Surfaces exposed to chemicals (acids, alkalis, or salt deposits) should be washed using copious amounts of water or steam cleaned. Allow to fully dry.
- Severely contaminated surfaces should be cleaned using an appropriate solvent.
- Remove all mill glaze from new metal.
- Feather in any sharp edges.
- Round off any sharp edges to a 2mm radius.
- All surfaces cleaned with water or steam cleaned should be allowed to dry a minimum of 24 hours before applying CIP, except for galvanised surfaces treated with Owaphos. Galvanised surfaces treated with Owaphos should be coated within 8 hours.
- Do not remove firm rust.
New or Bright, Clean Metal:
- Sand surface with 80 grit abrasive (nothing finer) to form a key.
- Thoroughly dust off.
- Note: New metal is classed as pickled stock or metal that has been sandblasted to remove any mill glaze and is not rusty. Alternatively for new or bright clean metal use PID 60.
Rusted/Oxidised Surfaces:
- Remove all loose and flaking rust
- Thoroughly dust off.
- Note: For excessively and deeply rusted surfaces apply a coat of Owatrol Oil.
Previously Coated Surfaces:
- Remove all loose, flaking, rust and paint.
- Feather in any sharp edges.
- Thoroughly dust off.
- Apply a coat of Owatrol Oil to the entire surface.
Galvanised (Zinc) Surfaces:
New:
- Treat with Owaphos to passivate the surface.
- Allow to fully dry or dry with a cloth (dabbing action only), forced air etc. DO NOT wipe dry.
- Note: It is imperative that the prepared surface is coated within 8 hours.
Weathered:
- Clean thoroughly with hot soapy water, Pura-Trol, steam clean or use a non-oxidising agent e.g. Acetone.
- Allow to dry a full 24 hours.
- Note: Weathered surfaces are those deemed to have been exposed to the elements for longer than 12 months. Any galvanised
surface 12 months or under should be treated as new.
Application Tools
- Brush
- Roller
- Spray (Airless Sprayer 0.4mm x 80° @1850 to 2000psi (128 to 138 bars)).
If applying Marine CIP by spray, adjust the product by adding 5% to 20% Owatrol Oil depending on nozzle size and type to bring it to the desired viscosity.
Application of Marine CIP Corrosive Inhibiting Primer
- Apply a thin layer of Marine CIP.
- DO NOT over apply. Marine CIP is a primer and its purpose is to penetrate the surface, not mask it.
- See “Application Tools” when applying by spray.
Restrictions
Due to the aggressive nature of some automotive paints combined with their tough, hard and inflexible finish it is recommended that a test is carried out with Marine CIP to ensure compatibility before commencing with the entire project.
While Marine CIP followed by an automotive paint may be applied to New and/or Brightly Cleaned Metal the use of PID60 is recommended for these surfaces.
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 Marine 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 to hot surfaces.
- Do not apply if cold and/or wet weather is expected within 24 hours.
- Stir product thoroughly before and during application.
