Product Details

Drying Times

Surface Preparation

• Paint only clean surfaces
• Remove all grease, oil, soluble contaminants, and other foreign matter by "solvent cleaning" (SSPC-SP1)

Application Conditions

Major Refurbishment

• Abrasive blast clean to Sa2 (ISO 8501:1:2007) or hydroblast to International Paint hydroblasting standard HB2M/H (If abrasive blasting, the area should be fresh water washed prior to commencement). Hydroblasting is only recommended for small ballast tank repairs, above water and topside areas
• Interbond 808 may be applied to surfaces prepared to International Paint Slurry Blasting Standard SB2M/H. Slurry blasting is only recommended for above water areas and topside areas

Repair/OBM

• Prepare areas of corrosion by mechanical cleaning to St3 (ISO 8501-1: 2007) or hydroblast to International Paint Standard HB2M/H. Abrade surrounding intact area and feather the edges
• Interbond 808 may be applied to International Paint Slurry Blasting Standard SB2M/H. Slurry blasting is only recommended for above water and topside areas
• If overcoating large areas of aged two component coatings, the surfaces should be high pressure fresh water washed prior to application. Consult your International Paint representative for specific recommendations regarding two component coatings suitable for overcoating with Interbond 808. Interbond 808 should not be used to maintain or overcoat one component ballast coatings
• When applying Interbond 808 as a two-coat scheme, Interbond 808 Aluminium must always be applied as the first coat

Application

Ballast Tank Installation Guide

Cargo Oil Tanks Installation Guide

Mixing

Material is supplied in 2 containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified.

• Agitate Base (Part A) with a power agitator
• Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator

Thinner

• International GTA220
• Thinning is not normally required
• Consult the local representative for advice during application in extreme conditions
• Do not thin more than allowed by local environmental legislation

Airless Spray

• Recommended Tip Range 0.45-0.66 mm (18-26 thou)
• Total output fluid pressure at spray tip not less than 190 - 246 kg/cm² (2700 - 3500 p.s.i.)

Brush

• Application by brush is recommended for small areas only
• Multiple coats may be required to achieve specified film thickness

Roller

• Not recommended

Cleaner

• International GTA822/GTA220

Work Stoppages and Clean Up

• Do not allow material to remain in hoses, gun or spray equipment
• Thoroughly flush all equipment with International GTA822/GTA220
• Once units of paint have been mixed, they should not be resealed, and it is advised that after prolonged stoppages work recommences with freshly mixed units
• Clean all equipment immediately after use with International GTA822/GTA220
• It is good working practice to periodically flush out spray equipment during the working day
• Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays
• Do not exceed pot life limitations
• All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation

Welding

• In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation

Limitations

• This product will not cure adequately below 5°C. Substrate temperature should not exceed 40°C
• Interbond 808 can be applied over a damp but drying surface - not a wet surface. It cannot be applied over pools of water or water droplets
• A simple test for dampness is as follows: With a finger, mark a 'V' on the surface to be coated. If drops of water collect at the bottom of the 'V', then the surface is wet not damp and should not be coated
• The surface may be dried however and coated if it does not become wet during application
• Interbond 808 series is can continue its cure process once immersed in water. However, early immersion following application will tend to retard coating cure and may result in soft films. See 'Drying Times, before flooding'
• The curing agent for Interbond 808 tends to go cloudy when stored at temperatures below 5°C. Warming the curing agent above 5°C will restore the clear nature of the produc.
• No adverse effect on performance is observed if the curing agent is cloudy when used
• Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions
• Consult your local International Paint representative for specific recommendations
• For optimum application properties bring the material to 25-30°C, unless specifically instructed otherwise, prior to mixing and application. Unmixed material (in closed containers) should be maintained in protected storage in accordance with information given in the STORAGE Section of this data sheet
• Technical and application data herein is for the purpose of establishing a general guideline of the coating application procedures 
• Test performance results were obtained in a controlled laboratory environment and International Paint makes no claim that the exhibited published test results, or any other tests, accurately represent results found in all field environments
• As application, environmental and design factors can vary significantly, due care should be exercised in the selection, verification of performance and use of the coating
